Formulas Used
Monthly Payment (Fixed-Rate Amortization)
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Where: M = Monthly payment (principal + interest) (USD), P = Loan principal (full loan amount) (USD), r = Monthly interest rate (annual rate / 100 / 12) (decimal), n = Loan term in months (months)

Origination Fee
Fee = P × (fee_pct / 100)
Where: Fee = Dollar amount deducted at disbursement (USD), P = Loan amount (principal) (USD), fee_pct = Origination fee as a percentage of the loan amount (%)
Source: Standard lender fee convention ✓ Verified
All-In Total Repayment Cost
Total = (M × n) + Fee
Where: Total = Complete cash outflow — all payments plus upfront fee (USD), M = Monthly payment (USD), n = Number of payments (months), Fee = Origination fee paid at disbursement (USD)

Key Insight
On a $25,000 business loan at 7.5% APR over 5 years with a 2% origination fee, the monthly payment is $500.95 and the all-in total cost is $30,556.92 — $5,056.92 in interest plus a $500 origination fee. The $500 fee is deducted upfront, so the effective cash received is $24,500. When comparing lenders, the all-in total repayment is more informative than the stated rate alone.
Frequently Asked Questions
What is a typical origination fee on a business loan?
Origination fees on business loans typically range from 1% to 5% of the loan amount, though alternative or short-term financing products can occasionally reach 8–10%. SBA 7(a) loans cap the upfront guarantee fee (a form of origination-adjacent cost) at 3.5% for loans over $150,000 under current SBA fee schedules — verify current rates on SBA.gov, as fee structures change annually. Commercial bank loans and credit union loans often charge 1–2%. Online business lenders may charge 3–6%. The origination fee is typically deducted from the disbursed amount, so a $100,000 loan with a 3% origination fee means the business receives $97,000 but repays the full $100,000 principal plus interest.
What is the difference between stated interest rate and effective APR on a business loan?
The stated interest rate is the annual rate applied to the outstanding principal balance each month to calculate the interest portion of each payment. The APR (Annual Percentage Rate) includes the stated rate plus certain fees — typically the origination fee — spread over the life of the loan, producing a higher effective annual cost figure. A loan with a 7% stated rate and a 3% origination fee on a 3-year term will have an effective APR of approximately 9–9.5%, depending on exactly how the fee is spread. When comparing multiple loan offers, use APR rather than stated rate for an apples-to-apples comparison.
What are typical repayment terms for small business loans?
Repayment terms vary significantly by loan type and purpose. SBA 7(a) loans for working capital typically allow up to 10 years; equipment loans run 5–10 years; real estate loans under SBA 504 programs can extend to 20–25 years. Conventional bank business term loans often use 3–7 year terms. Online and alternative lenders may offer shorter terms of 3–36 months, frequently at higher rates. This calculator supports any term from 3 to 360 months. Shorter terms produce higher monthly payments but lower total interest; longer terms reduce monthly payments but increase total borrowing cost.
If I need a specific amount of working capital, how do I account for the origination fee in the loan amount?
If the business needs a net amount after fees, the required loan amount is slightly higher than the target. The formula is: Required Loan Amount = Target Net Amount / (1 - origination_fee_percent / 100). For example, to receive $50,000 net with a 2% origination fee: $50,000 / (1 - 0.02) = $51,020.41. Borrowing $51,020 at 2% fee yields a $1,020.40 fee and $49,999.60 net — effectively $50,000. Recompute with the adjusted loan amount to see the revised monthly payment.

- U.S. Small Business Administration — Loans — Business loan types, term ranges, and fee structures including SBA guarantee fees
- Consumer Financial Protection Bureau — Loan Payment Application — Amortization formula and how monthly payments are applied to principal and interest
Limitations:
- Assumes a fixed interest rate for the entire loan term — variable-rate business loans will produce different results over time
- Origination fee is modelled as a flat percentage deducted at disbursement — some lenders roll the fee into the loan balance, which increases the principal owed and the total interest charged
- Does not include SBA guarantee fees, annual maintenance fees, closing costs, collateral appraisal costs, insurance requirements, or other lender-specific charges
- Assumes equal monthly payments for the full term — some business loans use interest-only periods, balloon payments, or non-monthly repayment schedules
When to consult a professional: Before committing to any business loan over $25,000, or when evaluating SBA loans, commercial real estate financing, or revolving credit facilities with complex fee structures
This calculator provides estimates based on the standard fixed-rate amortization formula and a flat origination fee applied at disbursement. Actual loan costs depend on credit history, collateral, lender policies, and market conditions. For SBA loans, guarantee fees apply in addition to origination fees and are not included here.
