Unsecured business loans: how they work and who should use oneUnsecured business loans: how they work and who should use one

Walk into any bank in the US and ask for an "unsecured" business loan and you'll likely come away surprised. The loan won't require you to pledge a specific asset - that part is true. But you'll almost certainly be asked to sign a personal guarantee, putting your house, your savings and your personal credit on the line if the business defaults.

That gap between what "unsecured" sounds like and what it actually means is the most common source of confusion in business lending. It's also the most expensive misunderstanding to make. This guide explains what an unsecured business loan really is, what it costs, who qualifies, and when it's the right choice for service businesses, software companies and other SMBs that don't have warehouses full of inventory or heavy equipment to pledge.

An unsecured business loan is financing issued without a specific business asset (real estate, equipment, inventory or accounts receivable) pledged as collateral. The lender's recovery in a default depends on the borrower's creditworthiness, business revenue and, in most cases, a personal guarantee from the owner.

The word "unsecured" describes the asset side of the agreement. It does not, on its own, describe the owner's personal liability. That's a separate clause in the loan agreement, and it's the one most borrowers miss.

Unsecured doesn't always mean no personal guarantee

A personal guarantee is a contractual promise that the business owner will repay the loan personally if the business cannot. It's a standard requirement on most "unsecured" loans from banks and many fintech lenders.

The SBA is explicit about this. SBA Form 148 requires anyone owning 20% or more of a business that takes an SBA-backed loan to sign an unconditional personal guarantee. Bank of America, PNC, Truist and Chase all require personal guarantees on their unsecured business loans, even when the loan amount is small. Most online lenders do too.

A handful of fintech and revenue-based lenders structure their products differently, underwriting on business performance rather than personal balance sheet, but this is the exception, not the rule. If avoiding a personal guarantee matters to you, the only way to know is to read the term sheet line by line.

The choice between a secured and an unsecured loan comes down to three things: what assets you're willing to pledge, how fast you need the money, and how much you're trying to borrow.

Secured loans are cheaper and bigger, but slower and riskier in a default - the lender takes the asset. Unsecured loans cost more and cap out lower, but they're faster and don't put a specific asset on the chopping block. For service businesses, software companies, agencies and professional services firms, unsecured is often the only realistic option, simply because there isn't much to pledge.

There isn't one product called "unsecured business loan." The category covers five distinct financing structures, each suited to a different need. Understanding which one fits your situation matters more than chasing the lowest headline rate.

Unsecured term loans

A lump-sum loan repaid in fixed monthly installments over a set term, typically 1 to 5 years. Banks price these at 6.8–11% APR for prime borrowers; online lenders price them at 12–45% APR or higher for higher-risk profiles. Best for one-off investments with a clear ROI - hiring a senior engineer, opening a new office, funding a 12-month marketing program.

Unsecured business line of credit

A revolving credit facility you can draw against as needed, paying interest only on what you use. Limits typically run from $10K to $250K. This is the right tool for managing working capital gaps - covering payroll while you wait on a big invoice, smoothing out seasonal dips, or keeping a cash buffer for opportunities you can't predict.

For service businesses with lumpy revenue (agencies waiting on client invoices, consultancies between project milestones, SaaS firms timing renewals), an unsecured line of credit is often more useful than a term loan because you only pay for the capital you actually use.

Revenue-based financing

A non-traditional structure where repayments are tied to a percentage of monthly revenue rather than a fixed schedule. The lender quotes a factor rate (typically 1.10–1.50×) instead of an APR - you receive the capital and repay it as a share of incoming revenue until the agreed total is paid. Repayments scale up in good months and down in slow ones.

Revenue-based financing suits businesses with predictable, recurring revenue: SaaS companies, subscription businesses, recurring service contracts. It's faster to access than a bank loan and, depending on the provider, may not require a personal guarantee - but read the agreement carefully.

Business credit cards

Often overlooked, but for amounts under $50K and short-term needs (under 12 months), a business credit card with a 0% introductory APR or rewards program can be cheaper than any other form of unsecured financing. The trade-off is that almost all issuers require a personal guarantee, and rates spike to 16–29% once the introductory period ends.

Merchant cash advances

A merchant cash advance (MCA) is a lump sum repaid via daily or weekly debits from your business bank account, priced as a factor rate that often translates to an effective APR of 40% to 350% or more, depending on how quickly your sales repay the balance. They're fast and accessible to businesses that can't qualify elsewhere - but the cost is high and the daily debit structure can strangle cash flow. Treat MCAs as a last resort, not a first option.

Eligibility depends sharply on the lender. The same business can be declined by a bank and approved by a fintech lender on the same day.

Banks (Bank of America, PNC, Truist, Chase) typically require a personal FICO score of 680–700 or higher (Chase looks for 680+, Bank of America requires 700+), two or more years of operating history, $100K–$250K in minimum annual revenue, and an existing business banking relationship. The bar is high because the rates are low.

Online and fintech lenders are more accessible. Most require six or more months of trading, $5K–$10K in minimum monthly revenue, a personal FICO score of 600 or higher, and a connected bank account or accounting platform for underwriting. Approvals come faster because more of the underwriting is automated.

Revenue-based and alternative financing partners weight business performance more heavily than personal credit. A SaaS company with strong MRR retention or a service business with a stable recurring contract base may qualify with a personal FICO score that wouldn't pass a bank's filter.

Industry matters too. Most lenders exclude regulated industries (cannabis, firearms, gambling, adult content), and may flag businesses operating across multiple high-risk categories.

The application process varies by lender, but the underlying steps are the same. Doing them in the right order saves time and protects your credit profile from unnecessary inquiries.

1. Define how much you need and what you'll do with it. Lenders ask, and a vague answer is a red flag. "We need $150K to hire two senior engineers and fund 9 months of payroll while we close enterprise contracts" is the right level of specificity.
2. Check your personal FICO and your business credit profile. Most lenders publish their floors. Knowing yours up front avoids wasted applications and the credit-score hits that come with them.
3. Gather your documents. At minimum: 6–12 months of business bank statements, the last two years of business tax returns, profit and loss statements, balance sheet, and personal financial information for any owner above 20%.
4. Compare offers. Apply with two or three lenders and compare total cost of capital - not just headline APR or factor rate. Include origination fees, prepayment penalties and personal guarantee terms.
5. Read the agreement carefully. Specifically: the personal guarantee clause, the default and acceleration clauses, and any covenants that restrict how you can run the business while the loan is outstanding.

The cost of unsecured business credit varies more than any other category of business financing. Three main factors drive the rate: the lender type, the borrower's risk profile, and the structure of the product.

• Bank unsecured term loans: 6.8–11% APR for prime borrowers (FICO 700+, $500K+ revenue, established business)
• Online fintech term loans: 12–45% APR, with rates climbing higher for higher-risk profiles
• Revenue-based financing: 1.10–1.50× factor rate (roughly 15–40% effective annual cost depending on repayment speed)
• Unsecured business line of credit: 8–25% APR on drawn balances for established borrowers
• Business credit cards: 0% introductory, then 16–29% APR
• Merchant cash advances: 40% to 350%+ effective APR depending on repayment speed

Always compare total cost of capital, not headline rates. A 15% APR loan with a 5% origination fee, prepayment penalty and 3-year minimum term can cost more than an 18% APR loan with no fees and free prepayment.

The case for unsecured financing is mostly about speed, flexibility and asset risk. The case against is mostly about cost and ceiling.

Pros: No specific business asset is at risk in a default. Approval and funding are faster than secured loans - often days rather than weeks. The application process is lighter. Asset-light businesses (services, software, agencies) can access capital they couldn't otherwise qualify for.

Cons: Interest rates are higher because the lender is taking more risk. Maximum loan amounts are lower - typically capped at $250K–$500K, even with strong financials. Most still require a personal guarantee, so the owner remains personally on the hook. Repayment terms are usually shorter, which means higher monthly payments.

Unsecured financing isn't right for every business or every situation. It works best for borrowers in five specific situations.

Service businesses with lumpy cash flow. Agencies, consultancies and professional services firms often have strong revenue but uneven timing - large invoices that take 60+ days to clear, or projects with milestone-based payments. An unsecured line of credit smooths these gaps without forcing you to pledge an asset you may not have.

Software companies investing ahead of revenue. SaaS and software businesses often need capital for hiring, product development or sales infrastructure before that investment shows up as MRR. Revenue-based financing or a term loan against existing recurring revenue is often a better fit than equity dilution at an early stage.

Asset-light businesses growing fast. If you don't have real estate, heavy equipment or large inventory positions, you don't have collateral to pledge. Unsecured is the only realistic option, and the question becomes which type (term loan, line of credit or revenue-based) matches the use case.

Businesses that need funding quickly. If the use case is time-sensitive - a hiring window, a one-off opportunity, or a contract that has to be funded before it can be delivered - the speed advantage of unsecured fintech lending often outweighs the higher rate.

Owners protecting specific assets. Even when collateral is available, owners sometimes prefer unsecured financing to keep specific assets (equipment, the building they own) out of the loan agreement. The premium pays for keeping options open.

It's harder, more expensive and increasingly product-specific. With a personal FICO score below 650, most banks will decline. Realistic options narrow to revenue-based financing (which weights business performance over personal credit), microloans through Kiva or Accion (small amounts, slow), or merchant cash advances (fast, expensive, treat as last resort).

A common red flag: lenders advertising "no credit check" with no other underwriting criteria. These are almost always predatory MCAs with effective APRs above 80%. A legitimate lender that doesn't lean on personal credit will lean on something else - revenue, recurring contracts, a business banking history. If a lender is checking nothing, the price is in the contract.

Most SMBs don't fail the bank's underwriting because the business is weak. They fail because the underwriting model is built for asset-heavy borrowers with two years of audited accounts, not a service firm running on recurring contracts or a software company with strong MRR but a short trading history. Wayflyer underwrites on what your business actually does. We look at revenue performance, contract base and how cash moves through your accounts, then build a financing offer that fits the way your business operates. Decisions take days, not weeks. Repayments are structured around your revenue, so they flex with the business instead of fighting it. For service businesses, software companies and asset-light SMBs that have been priced out or slowed down by traditional lenders, that's often the difference between funding the next move and missing it.

Is it hard to get an unsecured business loan?

Yes, and harder than secured loans, because the lender is taking on more risk. Most banks require a personal FICO score of 680–700+ depending on the lender, two or more years in business, and $100K+ in annual revenue. Fintech lenders are typically more flexible - most need six or more months of trading and $5K–$10K in minimum monthly revenue. Approval rates are lower across the board than for secured loans, and the businesses most likely to qualify are those with strong revenue, clean banking history and a clear use case for the capital.

Who is eligible for an unsecured business loan?

Eligibility varies sharply by lender type. Banks typically require a personal FICO score of 680–700+ depending on the lender (Chase looks for 680+, Bank of America requires 700+), 2+ years operating history, $100K–$250K minimum annual revenue, and an established banking relationship. Fintech lenders need 6+ months of trading, $5K–$10K minimum monthly revenue, and a connected bank or accounting platform. Revenue-based financing partners weight business performance - things like recurring revenue, contract base, and MRR retention - more heavily than personal credit. Industry matters too: regulated industries are widely excluded.

Does an unsecured business loan require a personal guarantee?

Almost always, even when the loan is described as unsecured. "Unsecured" means no specific business asset is pledged as collateral. It doesn't usually mean the owner has no personal liability. SBA Form 148 requires anyone owning 20% or more of an SBA-backed borrower to sign an unconditional personal guarantee. Most bank unsecured loans require one too. A small set of fintech and revenue-based lenders structure their products without a personal guarantee - read the term sheet carefully before signing.

What is the interest rate on an unsecured business loan?

Rates in 2026 vary widely by lender type and borrower profile. Banks price unsecured term loans at 6.8–11% APR for prime borrowers, in line with Federal Reserve Q4 2025 data. Online fintech term loans price at 12–45% APR, with rates climbing higher for higher-risk profiles. Revenue-based financing uses a factor rate of 1.10–1.50× (roughly 15–40% effective annual cost). Unsecured lines of credit run 8–25% APR on drawn balances for established borrowers. Merchant cash advances are the most expensive - 40% to 350%+ effective APR depending on how quickly the advance is repaid. Always compare total cost of capital, including fees, prepayment penalties and term length, not just headline rates.

How much can you borrow with an unsecured business loan?

Maximum amounts depend on the lender and the borrower's revenue. Major banks typically cap unsecured products at $100K - PNC and Truist both cap their unsecured small business loans at exactly $100K, and Bank of America requires collateral on lines of credit above $100K. Chase goes higher, up to $500K for established borrowers. Online fintech lenders generally fund $5K–$250K. Revenue-based financing typically funds up to one-third of annual revenue (roughly 1×–4× monthly revenue), so a business doing $100K/month could access $100K–$400K. Higher amounts are available but generally require a personal guarantee or move into secured territory.

How fast can you get an unsecured business loan?

Speed is the biggest difference between bank and fintech lenders. Banks typically take 4–8 weeks from application to funding, with paperwork, in-person reviews and manual underwriting. Online fintech lenders take 24 hours to 5 business days for approval, with funding 1–3 business days after acceptance. Revenue-based financing can be even faster - 24–48 hours from application to offer when a sales platform or accounting system is connected, with funding the next business day. If timing matters more than rate, fintech wins decisively.

What disqualifies you from an unsecured business loan?

The most common disqualifiers: a personal credit score below the lender's floor (typically 600 fintech, 680 bank); less than six months of trading history; recent bankruptcies or active tax liens; operating in a restricted industry (firearms, cannabis, gambling, adult content); inconsistent revenue beyond a normal seasonal pattern; an existing debt-service-coverage ratio under 1.25×. Most lenders publish their hard floors. Checking yours before applying protects your credit profile from unnecessary inquiries, which themselves can lower your score.

Can you get an unsecured business loan with no revenue or as a startup?

Rarely, and never on attractive terms. Most unsecured lenders require at least 6 months of trading history and minimum monthly revenue of $5K–$10K. For pre-revenue businesses, the realistic options are: an SBA microloan (up to $50K, requires a strong personal credit profile and a personal guarantee), a business credit card (small limit, requires personal guarantee), or financing secured against personal assets. Equity financing is often a better fit at the pre-revenue stage than debt - debt assumes you have cash flow to repay it.

Secured vs. unsecured business loans - which is better?

Neither is universally better. Secured loans are cheaper, larger and longer-term, but you risk losing the pledged asset in a default and the application process takes weeks. Unsecured loans are faster and don't put a specific asset at risk, but cost more and cap out lower. For asset-heavy businesses with real estate or significant equipment, secured usually wins on cost. For service businesses, software companies, agencies and other asset-light SMBs, unsecured is often the only realistic option - and the question becomes which type fits the use case.

An unsecured business loan is a useful tool for the right job. For service businesses managing lumpy cash flow, software companies investing ahead of revenue, and asset-light SMBs that don't have collateral to pledge, it's often the only realistic form of debt financing - and in many cases it's the right one.

The two things to get right before signing: understand exactly what "unsecured" means in your specific term sheet (especially the personal guarantee clause), and compare total cost of capital, not headline rates. The lender that quotes you the lowest APR isn't always the lender that costs you the least.

If you're weighing your options, start by mapping the use case to the right product. A working capital gap is a line of credit. A one-off investment is a term loan. Recurring revenue you can borrow against is revenue-based financing. Pick the structure first; pick the lender second.
