No property tax or insurance changes during the loan term

Mortgage Formula

The monthly mortgage payment is calculated using the standard formula for an amortized loan:

Monthly 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 × 12)

This formula accounts for the fact that each monthly payment includes both principal repayment and interest, with the interest portion decreasing over time as the principal balance decreases.

Worked Example

Let's calculate a mortgage for a $350,000 home with a 25-year term and 5% annual interest rate:

Example Calculation

Principal (P) = $350,000

Annual interest rate = 5% (0.05)

Monthly interest rate (i) = 0.05 / 12 ≈ 0.004167

Number of payments (n) = 25 × 12 = 300

Monthly payment (M) = $350,000 [0.004167(1 + 0.004167)³⁰⁰] / [(1 + 0.004167)³⁰⁰ - 1] ≈ $2,124.64

Total interest paid = ($2,124.64 × 300) - $350,000 ≈ $367,392

This example shows that over a 25-year mortgage, you would pay approximately $2,124.64 per month with about $367,392 in total interest.
