Formula Used
The calculator uses the standard mortgage payment formula:
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
This formula accounts for the interest that will be paid over the life of the loan, providing an accurate estimate of your monthly obligations.
Worked Example
Let's calculate a loan for $100,000 at 5% annual interest over 30 years:
- Principal (P) = $100,000
- Annual interest rate = 5% or 0.05
- Monthly interest rate (r) = 0.05 / 12 ≈ 0.004167
- Number of payments (n) = 30 × 12 = 360
Plugging these values into the formula:
Monthly Payment = $100,000 × (0.004167(1 + 0.004167)^360) / ((1 + 0.004167)^360 - 1)
≈ $100,000 × (0.004167 × 1.004167^360) / (1.004167^360 - 1)
≈ $100,000 × (0.004167 × 1.4856) / (1.4856 - 1)
≈ $100,000 × 0.006426 / 0.4856
≈ $100,000 × 0.01325
≈ $1,325.00
So, the estimated monthly payment would be $1,325.00.
