$500,000 Mortgage Calculator
Calculate your monthly payment for a $500,000 loan. Enter the interest rate and term to see your result.
Mortgage Calculator
Your mortgage rate (e.g. 6 for 6%).
e.g. 15 or 30.
Monthly Payment
$2,998
Rate scenario
What if your rate was 5%? Monthly payment: $2,684.108.
15 vs 30 year comparison
Same loan amount and rate (6%):
15-year term
$4,219.284/mo
30-year term
$2,997.753/mo
Extra payments to reduce term
Adding $100/month extra to principal: loan paid off in about 27.5 years (vs 30 years with no extra).
Amortization by year (principal vs interest)
Each bar shows total principal and interest paid in that year. Early years are mostly interest.
How This Calculator Works
Enter your loan amount (principal), the annual interest rate as a percentage, and the loan term in years. The calculator converts the annual rate to a monthly rate and the term to the number of monthly payments, then applies the standard amortization formula to produce your fixed monthly payment. This payment stays the same over the life of the loan; the split between principal and interest changes each month.
Formula Used
M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is principal, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly payments (years × 12).
Example Calculation
For a $250,000 loan at 6% annual interest over 30 years: monthly rate r = 0.06/12 = 0.005, n = 360. The monthly payment is approximately $1,499. A $200,000 loan at 5% for 30 years yields about $1,074 per month.
When to Use This Calculator
Use this calculator when comparing mortgage offers, budgeting for a home purchase, or checking how different rates or terms affect your payment. It is also useful for refinancing scenarios.
We use the standard loan formula with your principal, annual interest rate (converted to monthly), and term in years (converted to number of monthly payments).
No. The result is principal and interest only. Add property taxes and insurance (PITI) separately for a full monthly housing cost.
This calculator assumes fixed monthly payments. Extra principal payments reduce the loan balance faster and total interest; use an amortization calculator for that scenario.
