Business Loan Comparison Calculator: Find the Best Financing Option

The advertised rate on a business loan is never the real cost. A lender quoting 8% on an SBA loan does not mention the 2–3% SBA guarantee fee added to the loan balance, the $500 packaging fee, the mandatory life insurance premium, or the fact that the rate is variable and tied to the prime rate. A term loan advertised at 10% may carry a 5% origination fee that increases the effective cost to 11.5%+ when amortised over the loan term. A business line of credit at “prime plus 2” sounds affordable until you realise there is a $250 annual maintenance fee, a draw fee per transaction, and an unused line fee charged on the portion you have not borrowed.

The gap between the advertised rate and the true cost of borrowing — the effective APR — is where lenders make their money and where borrowers lose theirs. This calculator closes that gap. You enter the actual terms for up to four loan options (including all fees, not just the headline rate), and the spreadsheet calculates the effective APR, total cost of borrowing, monthly payment, and total amount repaid for each. It also checks whether each loan’s monthly payment is sustainable against your projected cash flow — because a cheap loan that strains your cash position is not actually cheap.

The Five Business Loan Types#

Understanding the options is the first step to comparing them fairly.

Term Loans#

A lump sum borrowed at a fixed or variable rate, repaid in regular instalments over a set period (typically 1–10 years for small business loans, up to 25 years for SBA loans). This is the most straightforward business financing: you borrow $100,000, pay it back over 5 years at a fixed rate, and the payments are predictable. Typical rates in 2026: 8–15% for bank term loans, 10–25% for online lenders, depending on creditworthiness and collateral.

SBA 7(a) Loans#

The most popular government-backed small business loan. The SBA guarantees a portion of the loan (up to 85% for loans under $150,000; 75% for larger loans), which reduces the lender’s risk and enables lower rates. Typical rates: prime + 2.25% to prime + 4.75% (currently approximately 9.75–12.25%), with terms up to 10 years for working capital and 25 years for real estate. The catch: the SBA guarantee fee (0.5–3.75% of the guaranteed portion) is added to the loan, and the application process is lengthy — 30–90 days is common.

SBA 504 Loans#

Designed for major fixed-asset purchases (real estate, heavy equipment). The structure is unique: a bank provides 50% of the project cost, a Certified Development Company (CDC) provides up to 40% through the SBA 504 programme, and the borrower provides 10% as a down payment. The CDC portion carries a fixed rate (currently approximately 5.5–6.5%), making this the cheapest long-term financing available for eligible purchases. Terms: 10 or 20 years. The limitation: 504 loans cannot be used for working capital or inventory.

Business Lines of Credit#

Revolving credit that you draw on as needed and repay, similar to a credit card but at lower rates. You pay interest only on the amount drawn, not the full credit limit. Typical rates: prime + 1% to prime + 8% (currently approximately 8.5–15.5%). Lines of credit are ideal for managing cash flow gaps, seasonal inventory purchases, and unexpected expenses. They are not ideal for large, one-time investments (a term loan is cheaper for that purpose).

Equipment Financing#

Loans or leases specifically for business equipment, where the equipment itself serves as collateral. Because the loan is secured by a depreciating asset, rates are typically lower than unsecured term loans: 6–15% depending on equipment type and borrower profile. Terms match the useful life of the equipment (3–7 years for most business equipment). The equipment itself secures the loan, so a default means the lender repossesses the equipment — not your other business assets.

Business Loan Type Comparison#

Loan Type	Typical Rate (2026)	Typical Term	Best For	Key Limitation
Bank Term Loan	8–15%	1–10 years	Established businesses with strong credit needing a specific amount	Requires strong financials; often needs collateral
SBA 7(a)	Prime + 2.25–4.75% (~9.75–12.25%)	Up to 10 yrs (25 for RE)	Businesses that need lower rates and longer terms; startups with a plan	Slow application process; SBA guarantee fee adds cost
SBA 504	~5.5–6.5% (CDC portion)	10 or 20 years	Real estate and heavy equipment purchases	Cannot be used for working capital; requires 10% down
Line of Credit	Prime + 1–8% (~8.5–15.5%)	Revolving (annual renewal)	Cash flow management, seasonal needs, emergency buffer	Interest rate is variable; annual fees; not for large purchases
Equipment Financing	6–15%	3–7 years	Specific equipment purchases	Secured by the equipment only; no general working capital

What the Spreadsheet Calculates#

Per-Loan Analysis#

For each loan option (up to four), you enter the principal amount (the amount you are borrowing, not the amount you need — fees may require borrowing more), the stated interest rate, the loan term in months, the origination fee (percentage or flat amount), any other upfront fees (SBA guarantee fee, packaging fee, application fee), ongoing fees (annual maintenance fee, draw fee, unused line fee), and the payment frequency (monthly is standard).

The spreadsheet calculates the monthly payment, the total interest paid over the loan term, the total fees paid, the total cost of borrowing (interest + all fees), the effective APR (the annualised cost including fees — this is the only number that makes different loan structures directly comparable), and the total amount repaid (principal + interest + fees).

Side-by-Side Comparison#

A summary dashboard shows all four loan options with their effective APR, monthly payment, and total cost. The cheapest option by effective APR is highlighted — which is not always the option with the lowest stated rate once fees are included.

Can You Afford This Loan?#

The affordability check is where most loan calculators stop being useful and this one starts. You enter your average monthly revenue and your average monthly operating expenses (or import these from your 13-week cash flow forecast or small business budget). The spreadsheet calculates your monthly cash flow before the new loan payment, the Debt Service Coverage Ratio (DSCR) — cash flow divided by the loan payment, and whether each loan passes the lender’s typical DSCR threshold (1.25× is the standard minimum — meaning your cash flow is at least 125% of the loan payment).

A DSCR below 1.0 means the loan payment exceeds your available cash flow — you cannot afford it. Between 1.0 and 1.25 is technically manageable but risky — one bad month and you miss a payment. Above 1.25 is the safety zone.

Loan ROI Calculator#

For loans funding a specific revenue-generating investment (equipment, expansion, marketing), the spreadsheet includes an ROI section. Enter the projected additional monthly revenue the investment will generate, and the calculator shows whether the investment’s return exceeds the loan’s cost — the basic test of whether borrowing makes sense.

How to Get the Best Business Loan Rate#

Know your numbers before you apply. Lenders evaluate your personal credit score (680+ for the best rates), business revenue and profitability (demonstrated via tax returns and financial statements), time in business (2+ years for most bank loans; some online lenders accept 6–12 months), collateral availability, and existing debt obligations. Having these organised before you apply speeds the process and demonstrates competence.

Compare at least three lenders, including different types. A bank, an SBA-preferred lender, and an online lender will each evaluate your application differently and offer different terms. The best fit depends on your time horizon (SBA loans are slower but cheaper; online loans are faster but more expensive), your need for flexibility (lines of credit vs term loans), and your creditworthiness (banks offer the best rates but have the highest thresholds).

Negotiate fees, not just rates. Origination fees are often negotiable, particularly with banks and credit unions competing for business. A 1% reduction in origination fee on a $200,000 loan saves $2,000. The spreadsheet shows exactly how fee changes affect the effective APR.

Consider the total cost, not the monthly payment. A longer loan term reduces the monthly payment but increases total interest. The spreadsheet compares total cost across different terms so you can make an informed trade-off between cash flow relief and total expense. The principles are identical to those in our mortgage refinance calculator — the maths of borrowing works the same whether the collateral is a house or a business.

Frequently Asked Questions#

What credit score do I need for a business loan?

For bank and SBA loans: 680+ personal credit for competitive rates, 700+ for the best terms. Online lenders may accept scores as low as 550–600 but charge significantly higher rates (15–30%+). Some lenders also check your business credit score (Dun & Bradstreet, Experian Business), though personal credit is typically the primary factor for small business loans.

How long does it take to get a business loan?

Online term loans: 1–7 days from application to funding. Bank term loans: 2–6 weeks. SBA 7(a) loans: 30–90 days. SBA 504 loans: 60–120 days. If speed matters, online lenders win — but you pay for that speed with higher rates. If cost matters, SBA loans win — but you pay for that savings with time and paperwork.

Should I choose a fixed or variable rate?

Fixed rates provide payment predictability — essential for businesses with tight cash flow. Variable rates (typically tied to prime) are currently higher than they were in 2020–2021 but may decrease if the Fed continues cutting rates. If you believe rates will decline and can absorb short-term payment variability, a variable rate may save money over the loan term. If predictability is more important, lock in a fixed rate.

What is an SBA guarantee fee and how does it affect my cost?

The SBA charges a guarantee fee on the guaranteed portion of 7(a) loans: 0% for loans up to $150,000 with maturity of 12 months or less, 2% for loans $150,001–$700,000, and 3%+ for loans above $700,000. This fee is typically rolled into the loan balance, which means you pay interest on the fee for the life of the loan. On a $500,000 loan with a 2.75% guarantee fee, that is $13,750 added to the balance — plus interest. The spreadsheet captures this by including the guarantee fee in the effective APR calculation.

Can I pay off a business loan early without penalty?

SBA 7(a) loans have a prepayment penalty of 3–5% in the first three years for loans with terms of 15+ years. Bank term loans and online loans may or may not have prepayment penalties — check the loan agreement. Lines of credit typically have no prepayment penalty (you can pay down and redraw freely). If early payoff is likely, verify the prepayment terms before signing and factor any penalty into your total cost comparison.

Is it better to use a business loan or personal savings for a business investment?

Using a loan preserves your cash reserves (which provide a safety buffer) and allows you to leverage the business’s returns against the loan’s cost. If the investment generates returns above the loan’s effective APR, borrowing creates value. If you use personal savings, you avoid interest costs but deplete your safety net. The ROI section of the spreadsheet helps model this: if the investment returns 20% and the loan costs 10%, borrowing doubles the net return on the invested amount.

What is the DSCR and why do lenders care about it?

The Debt Service Coverage Ratio is your monthly (or annual) cash flow divided by your total debt payments. Lenders require a minimum DSCR — typically 1.25× — to ensure the business can comfortably make loan payments even if revenue dips temporarily. A DSCR of 1.0 means every dollar of cash flow goes to debt service, with nothing left for operations or unexpected costs. Below 1.0 means you are cash-flow negative after debt payments. The spreadsheet calculates DSCR for each loan option using your actual financial data.
