Business Loan Payment Calculator: Payment, Interest and True Cost
Estimate the payment on a term loan, SBA loan, equipment loan or line of credit draw, see how much interest you will pay, and what an origination fee really does to your rate.
Business Loan Payment Calculator (Small Business Loan Calculator)
Works for term loans, SBA loans, equipment financing and lines of credit with a fixed repayment.
24 to 60 months is common for term loans
Deducted from the loan proceeds
Shows the payment as a share of your monthly deposits

Illustrative estimate, not an offer. Assumes a fixed rate, equal payments and no prepayment. Your rate, fees and term depend on the lender and your file.
How Do You Calculate a Business Loan Payment?
Divide the APR by the number of payments per year to get the periodic rate r, then use Payment = P × r ÷ (1 − (1 + r)^−n), where P is the loan amount and n is the number of payments. A $150,000 loan at 14% over 36 months works out to about $5,127 a month and roughly $34,559 in total interest.
How to Use the Calculator
Enter the loan amount, the interest rate as an APR, the term in months and any origination fee. Choose the payment schedule on your offer: most bank and SBA loans pay monthly, while many online term loans debit weekly or every two weeks. Add monthly revenue to see what share of your deposits the payment takes.
You get the payment, the total interest, what you actually receive after fees, an effective APR that includes the fee, and a year-by-year schedule showing how fast the balance comes down.
The Payment Formula
Fixed-payment business loans amortize: each payment covers that period’s interest first, and the rest reduces the balance. Early payments are interest-heavy; later ones are mostly principal.
Worked Example: $150,000 at 14%
| Term | Monthly payment | Total interest | Total of payments |
|---|---|---|---|
| 24 months | $7,201.93 | $22,846 | $172,846 |
| 36 months | $5,126.64 | $34,559 | $184,559 |
| 60 months | $3,490.24 | $59,414 | $209,414 |
Illustrative, fixed rate, no fees. A 3% origination fee on the 36-month loan leaves $145,500 in proceeds and lifts the effective APR to about 16.2%.
The trade-off is always the same: stretching the term cuts the payment by a third or more, but the total interest can nearly double. Pick the shortest term your cash flow can carry comfortably in a slow month.
How Lenders Judge Whether You Can Afford It
Banks, SBA lenders and most term-loan funders measure debt service coverage: how many times your cash flow covers all your debt payments, including the new one. They also look at time in business, credit, and your business bank statements.
- Existing payments count. An open merchant cash advance or equipment note reduces what you can borrow. See funding with an existing MCA.
- Credit shapes the rate. Stronger scores price lower; below the mid-600s the options narrow. See strong revenue with a 550 score.
- History matters. Two years or more opens term loans and SBA loans; newer businesses usually start with revenue-based products.
Which Products This Calculator Fits
Use it for business term loans, SBA 7(a) loans, equipment financing, and a line of credit draw repaid over a fixed period. For a merchant cash advance priced with a factor rate, use the factor rate calculator instead, then put both side by side in the funding comparison tool.
Monthly Payment on a $100,000 Business Loan
The most common question we get on this page. Here is the principal-and-interest payment on $100,000 at the rates lenders are quoting in October 2026, with Prime at 7.00%.
| Rate | 1 year | 2 years | 3 years | 5 years | 10 years |
|---|---|---|---|---|---|
| 8% (bank line or term loan) | $8,699 | $4,523 | $3,134 | $2,028 | $1,213 |
| 10% (SBA 7(a) at Prime + 3) | $8,792 | $4,614 | $3,227 | $2,125 | $1,322 |
| 13.5% (SBA 7(a) cap on small loans) | $8,955 | $4,776 | $3,393 | $2,301 | $1,523 |
| 18% (online term loan, good file) | $9,168 | $4,992 | $3,615 | $2,539 | $1,802 |
| 30% (online term loan, weaker file) | $9,748 | $5,591 | $4,245 | $3,235 | $2,585 |
Interest only, a $100,000 draw on a line of credit costs about $667 a month at 8% and $833 at 10%. A $100,000 revenue-based advance at a 1.25 factor is $125,000 of total payback; over nine months that is roughly $3,200 a week, which no APR table captures well, so use the factor rate calculator for those.
Business Line of Credit Payment Calculator: How Draw Payments Work
This calculator works for lines of credit too, with one adjustment: calculate each draw separately. A bank line is usually interest-only on the outstanding balance, so a $50,000 balance at Prime + 2 (9.00%) costs about $375 a month until you repay principal. An online line amortizes each draw over 6 to 18 months, often with a fee instead of a rate: a $50,000 draw at a 2.5% fee repaid weekly over 12 months is roughly $1,010 a week, $52,500 in total. Enter the draw amount, the repayment term and either the APR or the fee converted to an APR, and the calculator returns the weekly or monthly figure. Rates by line type are in business line of credit rates.
Which Rates to Plug In (October 2026)
| Product | Rate range to test | Typical term |
|---|---|---|
| SBA 7(a) variable | 10.00% – 13.50% | 7 – 10 years |
| SBA 504 (fixed) | 6.3% – 7.0% | 10 – 25 years |
| Bank term loan | 7% – 11% | 3 – 7 years |
| Bank line of credit | 8% – 11% (Prime + 1 to 4) | Revolving |
| Equipment financing | 9.9% – 24% | 3 – 7 years |
| Online term loan | 10% – 36% | 1 – 5 years |
| Online line of credit | 8% – 36% APR equivalent | 6 – 18 months per draw |
Prime moved to 7.00% in September; a further quarter-point move on October 28 would add about $12 a month per $100,000 on a 10-year SBA loan. Scenarios are in prime rate is 7%: what it means for business loan rates.

Common Questions
What is a typical interest rate on a business loan?
It depends on the product and the file. SBA 7(a) loans are among the lowest-cost options and have rate caps tied to the Prime Rate; online term loans and lines of credit price higher, and revenue-based products higher still.
Does an origination fee change my APR?
Yes. The fee is usually taken from the proceeds, so you pay interest on the full amount while receiving less. On a 36-month loan at 14%, a 3% fee raises the effective APR to roughly 16.2%.
Is a weekly payment cheaper than monthly?
Slightly, because the balance falls faster, but the difference is small. The bigger question is cash flow: weekly debits suit businesses with steady weekly deposits.
Can I pay a business loan off early?
Many term loans allow it and you save the remaining interest, but some carry prepayment penalties. Check the agreement before you sign.
How much is the monthly payment for a $100,000 business loan?
At October 2026 rates: about $2,125 a month over five years at 10% (an SBA 7(a) at Prime + 3), $2,028 at 8%, $2,539 at 18% and $3,235 at 30%. Over 10 years at 10% it is about $1,322. A $100,000 interest-only line of credit draw costs about $667 to $833 a month at 8% to 10%.
Can I use this calculator for a business line of credit?
Yes. Calculate each draw as its own loan: for a bank line, use the interest-only cost (balance × rate ÷ 12); for an online line, enter the draw, its 6- to 18-month repayment term and the fee converted to an APR.
