Formula: down payment = price × percent / 100. Loan amount = price − down payment. Example: $400,000 price × 20% = $80,000 down, $320,000 loan.
Frequently Asked Questions
How much should I put down on a house?
20% is traditional and avoids private mortgage insurance, but many loan programs allow 3-10% with PMI.
How does down payment affect my mortgage?
A larger down payment reduces your loan amount, lowers monthly payments, and saves significant interest over the life of the loan.
Are closing costs separate from the down payment?
Yes — closing costs typically run 2-5% of the home price and are paid in addition to the down payment.
How can I verify this calculation manually?
Most calculations can be verified with a calculator app, spreadsheet, or by hand using the underlying formula (shown on the page). For complex multi-step calculations, verify each step independently before trusting the final number.
What should I do if the result seems off?
If the result seems wrong, check: (1) inputs are in the right units, (2) the formula matches your problem, (3) you did not transpose any numbers, (4) rounding is not causing small differences. If everything checks out and the answer still surprises you, that may be the actual result — counterintuitive outputs are common in real calculations.
