Mortgage Payment Formula
The standard mortgage payment formula is based on amortization:
Monthly Mortgage Payment (PMT):
iniCopyEditPMT = P × [r(1 + r)^n] / [(1 + r)^n – 1] Where:
- P = Loan Amount (Principal)
- r = Monthly Interest Rate (Annual Rate ÷ 12)
- n = Total Number of Payments (Loan Term × 12)
This formula helps calculate the fixed monthly amount needed to pay off the mortgage in full over time.
Example Calculation
Let’s say:
- Loan Amount: $250,000
- Interest Rate: 6.5%
- Loan Term: 30 years
Step 1:
Monthly interest rate = 6.5% ÷ 12 = 0.5417% or 0.005417
Step 2:
Total payments = 30 × 12 = 360 months
Step 3:
Use the formula:
nginxCopyEditPMT = 250,000 × [0.005417(1 + 0.005417)^360] / [(1 + 0.005417)^360 – 1] ≈ $1,580.17 Result:
Your monthly payment will be approximately $1,580.17 (excluding taxes and insurance).

Helpful Tips for Mortgage Planning
- Aim for 25–30% of Gross Income
Your monthly mortgage payment should be a manageable portion of your income. - Compare Interest Rates
A small difference in rates (even 0.25%) can save thousands. - Understand Fixed vs. Variable Rates
Fixed = stable payments; Variable = potential savings/risk. - Account for Extra Costs
Don’t forget property taxes, HOA fees, insurance, and maintenance. - Consider Prepayment
Extra payments toward the principal can reduce interest and term.
