Free Loan Calculators Online
Calculate loan payments, amortization schedules, and compare lending options.
Understanding your loan obligations before signing any agreement is one of the smartest financial moves you can make. Our loan calculators let you model monthly payments for personal loans and mortgages side by side, compare different interest rates and term lengths, and see exactly how much you will pay in total interest over the life of the loan. Use the Loan Payment Calculator for general borrowing scenarios and the Mortgage Calculator for home-specific financing with property tax and insurance estimates built in.

How Loan Calculators Work
Every standard loan follows the same amortization formula. You borrow a principal amount, the lender charges interest on the outstanding balance, and you repay in fixed installments over a set term. Our calculators break each payment into its principal and interest components so you can see how your balance decreases over time.
Loan Payment Calculator
Enter any loan amount, annual interest rate, and repayment term to see your monthly payment instantly. This tool works for auto loans, personal loans, student loans, and any fixed-rate scenario. Adjust the inputs to compare how a shorter term increases monthly payments but reduces total interest.
Mortgage Calculator
Our Mortgage Calculator factors in property taxes, homeowner's insurance, and PMI to show your true monthly housing cost — not just the principal and interest portion that lenders emphasize.
Key Loan Concepts
- Amortization — Early payments are interest-heavy; later payments are principal-heavy.
- APR vs. Interest Rate — APR includes fees and other costs, reflecting the true annual cost of the loan.
- Loan-to-Value Ratio — For mortgages, ratios above 80% typically require private mortgage insurance.
Frequently Asked Questions
Monthly payments use the amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments. Our Loan Payment Calculator handles this instantly — just enter your loan amount, rate, and term.
A basic loan payment calculator computes principal and interest only. A mortgage calculator adds housing-specific costs like property tax, homeowner's insurance, and PMI to show your complete monthly obligation. Use the mortgage calculator when evaluating a home purchase and the loan calculator for auto loans, personal loans, or student debt.
Three strategies work: choose a shorter loan term, make extra payments toward principal, or secure a lower interest rate. Our calculators let you model each scenario. For example, switching from a 30-year to a 15-year mortgage roughly doubles your monthly payment but can cut total interest by more than half.
