Below is the step-by-step calculation used to determine the result.
Answer
$6,326.35
M = $800,000 × [0.4167%(1 + 0.4167%)^180] / [(1 + 0.4167%)^180 − 1] = $6,326.35
Loan amount
$800,000 at 5.0% for 15 years
Monthly rate
5% ÷ 12 = 0.4167%
Number of payments
15 × 12 = 180
Monthly payment
$6,326.35

How Mortgage Payments Are Calculated
- 1.The formula is M = P × [r(1+r)^n] / [(1+r)^n − 1]
- 2.P (principal) = $800,000
- 3.r (monthly rate) = 5% ÷ 12 = 0.4167%
- 4.n (total payments) = 15 years × 12 = 180 payments
- 5.Result: $6,326.35 per month for principal and interest
What This Payment Means in Practice

- •Consider the 28/36 rule: housing costs should not exceed 28% of your gross monthly income
- •Making one extra payment per year can shave years off your mortgage and save thousands in interest
- •Compare this with a 15-year term to see the trade-off between lower monthly payments and total interest paid
