About the Down Payment Calculator
steady year-round volume with home buying and mortgage planning search intentThe Down Payment Calculator is a free online home buying tool designed to help you determine the optimal down payment amount for a home purchase and compare different down payment scenarios side by side. It calculates monthly mortgage payment (principal and interest), loan amount, LTV ratio, PMI costs, total interest, and total cost. Includes a multi-scenario comparison table showing 10%, 20%, and 25% down alongside your plan, and a break-even analysis for extra down payments. Pair it with our Mortgage Calculator for a full amortization schedule or our House Affordability Calculator to determine how much you can afford.
Enter the home price, down payment percentage (with quick presets for 3.5% FHA, 5%, 10%, 15%, 20%, and 25%), interest rate, and loan term (15, 20, or 30 years). Add optional closing costs as a percentage of price and an extra down payment amount for break-even analysis. The tool instantly shows monthly P&I payment, down payment amount, loan amount, LTV ratio, and total interest. When the down payment is below 20%, a PMI alert shows the monthly and annual PMI cost. The full cost picture combines down payment, closing costs, and total P&I paid over the full term. The Extra Down Payment Benefit section (when an extra amount is entered) shows the monthly savings, break-even period in months and years, and total savings over the full term. A Scenario Comparison table shows your plan side by side with 10%, 20%, and 25% down options across 8 key metrics with the best value highlighted. A Down Payment Reference table covers all common options from 3.5% FHA minimum through 25% large down payment.
Formulas & Mathematical Theory
Down Payment Percentage
The percentage of the home price paid upfront in cash. A down payment of 20% or more eliminates the need for private mortgage insurance (PMI).
Loan-to-Value Ratio (LTV)
The loan amount divided by the home price. Lenders use LTV to assess risk — LTV above 80% typically requires PMI.
