Formula Used
The calculator uses the standard mortgage payment formula:
Mortgage Payment Formula
M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years multiplied by 12)
This formula calculates the fixed monthly payment for a loan with a fixed interest rate.
Worked Example
Let's calculate a mortgage payment for a $200,000 loan with a 4% annual interest rate over 30 years:
- Principal (P) = $200,000
- Annual interest rate = 4% or 0.04
- Monthly interest rate (i) = 0.04 / 12 ≈ 0.003333
- Loan term in months (n) = 30 × 12 = 360
Plugging these values into the formula:
Calculation Steps
M = 200,000 [ 0.003333(1 + 0.003333)360 ] / [ (1 + 0.003333)360 - 1 ]
After performing the calculations:
M ≈ $1,073.64 per month
This example shows that a $200,000 mortgage at 4% interest over 30 years would have a monthly payment of approximately $1,073.64.
