Business Loan Calculator
Estimate the payment and true cost of a business loan. Enter the amount, term, an interest rate or factor rate, the payment frequency and any fees to see each payment, the total repaid and the effective APR.
Total repaid = amount × factor (common for short-term and cash-advance financing).

How business loan payments and APR are calculated
For a loan priced with an annual interest rate, the rate per payment is i = annual rate ÷ payments per year, and the payment is P = L × i ÷ (1 − (1 + i)−n), where n is the number of payments (12 a year monthly, 26 biweekly, 52 weekly or about 252 business days daily).
For a loan priced with a factor rate, the total repayment is simply amount × factor, split into equal payments. A factor of 1.25 on $50,000 means repaying $62,500, no matter how quickly.
The effective APR puts both on the same footing. It is the yearly rate i × payments per year that makes the money you actually receive (amount minus upfront fees) equal to the present value of all payments. Short terms, frequent payments and upfront fees all push the APR up.
Factor rate vs. APR ($50,000, daily payments)
| Factor rate | Term | Total repaid | Daily payment | Approx. APR |
|---|---|---|---|---|
| 1.10 | 6 months | $55,000 | $436.51 | 38.5% |
| 1.20 | 6 months | $60,000 | $476.19 | 74.8% |
| 1.20 | 12 months | $60,000 | $238.10 | 37.5% |
| 1.30 | 9 months | $65,000 | $343.92 | 73.0% |
| 1.40 | 12 months | $70,000 | $277.78 | 71.3% |
APR figures assume no fees and 252 business-day payments a year. Lenders may calculate differently; ask for the APR and the total cost of capital in writing before you sign, and check for prepayment terms (with a factor rate, paying early often saves nothing).
Frequently asked questions
How are business loan payments calculated?
For an interest-rate loan, divide the annual rate by the number of payments per year to get the periodic rate i, then use P = L × i ÷ (1 − (1 + i)^−n). $100,000 at 10% over 36 monthly payments is about $3,226.72 a month.
What is a factor rate?
A factor rate, often 1.1 to 1.5, is a multiplier used by short-term lenders and merchant cash advances. You repay the amount times the factor: $50,000 at 1.3 means $65,000 in total. It is not an interest rate, and the equivalent APR is usually much higher.
How do I convert a factor rate to APR?
Find the periodic rate at which the present value of all payments equals the amount you receive, then multiply by the number of payments per year. This calculator does that for you. A 1.2 factor repaid daily over 6 months works out to an APR of roughly 75%.
Why is the effective APR higher than the interest rate?
Upfront fees reduce the money you actually receive while payments stay the same, so the true borrowing cost rises. Shorter terms make fees matter even more because they are spread over less time.
Do weekly or daily payments cost more?
With the same annual rate, more frequent payments reduce the balance slightly faster, so total interest is a bit lower. But they put more pressure on cash flow, and daily-payment products are often priced with high factor rates.
What fees do business lenders charge?
Common fees include origination or underwriting fees (often 1% to 5%), packaging or documentation fees, SBA guarantee fees and late or prepayment fees. Include the upfront ones in the fee fields to see their effect on APR.
