Business Loan Calculator
Monthly payment and total interest for business loan at specified rate and term
Calculate business loan monthly repayment and the cumulative interest paid across the loan's full term at any rate and amortisation length.
What this tool does
This calculator models business loan repayment by computing your monthly payment amount and the total interest charges across the full loan term. You enter the loan amount, annual interest rate, and repayment period in years. The tool then estimates your monthly payment obligation, cumulative interest paid over time, and the total amount you'll repay by loan end. The monthly payment and interest total are driven primarily by the loan amount and annual rate—higher amounts or rates increase both figures—while a longer term spreads payments across more months, typically lowering each payment but raising total interest. A typical scenario involves comparing how different term lengths affect affordability and total cost. The calculator assumes consistent monthly payments and a fixed rate throughout the loan period, and does not account for fees, penalties, early repayment, or changes in circumstances. Results are estimates for illustration purposes.
Quick answer: with the default values, the result is $2,027.64 (Monthly Payment). Adjust the values below for your own figures.

Business Loan Payment Calculation
A business loan amortises on the same arithmetic as a consumer one. Each monthly payment covers the interest accrued on the outstanding balance and puts the remainder against the principal, so the interest share is largest at the start and falls as the balance does. This calculator returns the monthly payment, the total interest and the total repaid for a given amount, rate and term, which is what makes two offers on different terms comparable.
Typical Business Loan Terms
Rates and terms vary by product, by lender and by market, and any specific figure dates quickly, so the durable part is the ordering rather than the levels. Secured lending against an identifiable asset, such as equipment finance, tends to price below unsecured lending, because the collateral reduces the lender's loss on a default. Government-backed small-business schemes, where a market runs them, tend to price below comparable commercial lending for the same reason, since a partial public guarantee does that job instead. Revolving facilities such as a line of credit price above term loans for the flexibility. Short-dated products, invoice finance and merchant advances sit at the expensive end, and their cost is often quoted per month or as a flat fee rather than as an annual rate, which makes them look cheaper than they are until converted. Term lengths tend to follow the asset: longer for equipment, shorter for working capital. The figure to enter here is the one a specific lender has quoted, converted to an annual rate.
Worked Example for Typical Business Loan
Loan amount 100,000. Annual rate 8%. Term 5 years. Monthly payment 2,028. Total interest 21,659. Total paid 121,659. Loan pays back principal plus 21.7% in total interest over 5 years. Alternative longer term (10 years) reduces monthly payment to 1,213 but total interest grows to 45,593 — 45% total interest versus 22% on shorter term. Business loan decisions balance cash flow constraints against total interest cost.
What the Calculator Does Not Model
Several costs sit outside the figure. Arrangement or origination fees are charged up front and are often quoted as a percentage of the amount borrowed, which raises the effective cost above the headline rate. Larger facilities can carry closing costs on top. Some products penalise early repayment. Collateral has its own costs, valuation and registration among them, and personal guarantees are common on smaller facilities. Variable-rate loans move with the rate environment, while this calculator holds the rate fixed for the whole term. Where a lender quotes an all-in figure such as an APR, entering that rather than the headline rate gets closer to the real cost.
Business Loan Strategic Use
Different products suit different purposes. Equipment finance is straightforward against a specific asset, and the collateral usually brings the rate down. Working capital lending bridges a cash flow gap but costs more, since there is nothing securing it. Expansion financing is the case where the borrowing has an identifiable source of repayment, in the additional revenue it funds. Emergency financing is typically the most expensive, because it is arranged under time pressure. A line of credit is flexible, though a balance that is never cleared turns a revolving facility into long-term debt at revolving rates. What separates these is whether the borrowing funds something that generates a return or covers a genuine necessity, since that is what has to carry the interest cost.
Business loan of $100,000 at 8% over 5 years costs $2,027.64 monthly.

Sources & Methodology
Methodology
This calculator uses the standard amortisation formula to compute monthly loan payments. It converts the annual interest rate to a monthly rate, then applies the formula across the total number of monthly periods. The monthly payment amount is held constant throughout the loan term. Total amount paid is calculated by multiplying the monthly payment by the number of months. Total interest owed is derived by subtracting the original loan amount from the total paid. The model assumes a fixed interest rate with no rate changes over the loan term, regular monthly payments with no missed or extra payments, and no fees, prepayment penalties, or additional charges. It does not account for payment holidays, variable rates, compounding frequency variations, or lender-specific terms that may apply to your actual loan agreement. Results are estimates for comparison purposes.
