Monthly Payment
What Is a Mortgage Payment?
A mortgage payment typically includes:
- Principal: The portion of the loan that reduces the balance you owe.
- Interest: The cost of borrowing money, determined by the annual interest rate.
- Taxes & Insurance: Optional but commonly included in total monthly payments.
Our calculator focuses on principal and interest, giving you a clear baseline for planning your monthly expenses.
How the Mortgage Calculator Works
The calculator uses the standard mortgage formula:M=P×(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of payments (years × 12)
This formula accounts for compounding interest, ensuring that the monthly payment accurately reflects the loan terms.

- Interest rate: 6.5% annually
- Loan term: 30 years
Step 1: Convert annual interest to monthly: 6.5 ÷ 12 = 0.5417% per month
Step 2: Total payments: 30 × 12 = 360 months
Step 3: Apply mortgage formula:M=315,000×(1+0.005417)360−10.005417(1+0.005417)360
Result: $1,993.96 per month
