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.

Business Loan Payment Calculation
Business loans use same amortization math as consumer loans — monthly payment covers interest on outstanding balance plus principal reduction. Over loan term, early payments predominantly interest while later payments predominantly principal. Calculator quantifies specific monthly payment and total interest cost for user-supplied loan amount, rate, and term. Essential for evaluating business loan affordability, comparing loan offers, and planning cash flow around loan obligations.
Typical Business Loan Terms
SBA 7(a) loan rates: 8-12% typical currently for established businesses. Business line of credit: 7-15% depending on credit. Equipment financing: 5-10% for equipment-collateralized loans. Short-term business loans: 15-30% APR for 6-18 month terms. Invoice factoring: 2-5% per month effective rate. Merchant cash advance: 40-80% effective APR (expensive, often last resort). Term lengths: 3-7 years typical for SBA, 1-3 years for short-term, 5-10 years for equipment financing.
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
Origination fees (typically 1-5% of loan amount, paid upfront). Closing costs for larger loans (1-3% additional). Prepayment penalties on some loan types. Collateral requirements and specific collateral costs. Personal guarantees common for small business loans. SBA loan processing fees and requirements. Variable rate loans where payment changes with rate environment. The calculator uses fixed-rate assumption; specific loan products often include additional costs.
Business Loan Strategic Use
Equipment financing: straightforward for specific asset purchases, collateral reduces rate. Working capital loans: help bridge cash flow gaps but expensive — use only when clearly productive. Expansion financing: strongest case — additional revenue from expansion covers loan costs. Emergency financing: most expensive option, avoid if possible. Line of credit: flexible but avoid becoming permanent debt. Specific loan purpose should justify specific cost through returns or necessity; Borrowing without clear productive purpose.
Business loan of $100,000 at 8%% over 5 years years costs 2,027.64 monthly.

Sources & Methodology
Methodology
This calculator uses the standard amortization 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.
