Loan Calculator

Estimate your monthly payment with principal, interest, taxes, insurance, HOA or other fees, PMI, and optional extra principal payments.

Loan basics

Use the financing terms that match the scenario you want to compare before adding escrow costs and PMI.

Taxes, insurance, and PMI

Escrow items and PMI can materially change the monthly payment even when the principal and interest do not.

Enter property price if you want the calculator to estimate when PMI drops off at 80% loan-to-value.

How to Use the Loan Calculator

Estimate your monthly payment with principal, interest, taxes, insurance, HOA or other fees, PMI, and optional extra principal payments. This calculator is part of our mortgage & loans collection, where readers compare payment scenarios, borrowing costs, affordability, refinance math, and payoff timing before making a decision. Model monthly payments, APR, amortization, refinance savings, points, PMI, and rent-versus-buy so you can compare scenarios before applying.

Start with realistic values for Loan Amount, Interest Rate (APR), Loan Term, and Extra Principal Payment. Those inputs usually carry the biggest weight in the estimate, so it helps to change one assumption at a time and review how the output moves.

When you review the output, look beyond the single headline number. Compare conservative and aggressive assumptions, because the range between those scenarios often reveals more about monthly payment, total interest, affordability, and payoff speed than one estimate on its own.

After you review the result, compare it with Annual Percentage Rate (APR) Calculator, Payment / Amortization Calculator, and Loan Affordability Calculator. Looking at related calculators side by side can show whether the main trade-off is monthly payment, total interest, affordability, and payoff speed, and it gives you a better starting point for a lender conversation or financial planning decision.

Frequently Asked Questions

Use the Loan Calculator to test realistic scenarios before you borrow, save, invest, or change a payment strategy. Start with Loan Amount, Interest Rate (APR), Loan Term, and Extra Principal Payment, review the result, and then adjust one input at a time so you can compare the impact clearly.

Inputs such as Loan Amount, Interest Rate (APR), Loan Term, and Extra Principal Payment usually drive the result the most. In the mortgage & loans category, small changes in rates, term length, upfront fees, escrow costs, and payment strategy can materially change the estimate, so it is worth testing conservative assumptions as well as optimistic ones.

Compare the result with Annual Percentage Rate (APR) Calculator, Payment / Amortization Calculator, and Loan Affordability Calculator. That gives you better context for deciding whether your main priority is monthly payment, total interest, affordability, and payoff speed, rather than relying on a single estimate in isolation.
