About Mortgage Calculator
Enter a home price, down payment (in dollars or percent), interest rate, and term, and the calculator applies the standard amortization formula to show your monthly principal & interest. Add yearly property tax, insurance, and monthly HOA dues to see the full monthly payment, and PMI is included automatically whenever the down payment is under 20%.
Beyond the monthly number, you get the total interest paid over the life of the loan, the all-in total cost, and the payoff date — useful for comparing a 15-year against a 30-year term.
Common uses
- Check what a listing would actually cost per month before talking to a lender
- Compare 15 vs 20 vs 30-year terms on the same house
- See how a bigger down payment changes PMI and total interest
Example
Input
$375,000 home · 20% down · 6% · 30 years
Output
P&I $1,798.65/mo · total interest $347,515
Limitations
- Estimates only: real quotes include lender fees, points, and escrow rules this tool doesn't model.
- PMI is approximated as a flat annual rate and assumed for the whole term while down payment is under 20%; in practice it drops off at ~20% equity.
