Formula Used

The calculator uses the standard mortgage payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount (Home Price - Down Payment) i = Monthly interest rate (Annual Rate / 12 / 100) n = Number of payments (Amortization Period × 12)

Total interest paid is calculated as:

Total Interest = (Monthly Payment × Number of Payments) - Principal

Worked Example

Let's calculate a mortgage for a $500,000 home with a 20% down payment, 5-year term, and 5% interest rate:

Principal = $500,000 - ($500,000 × 20%) = $400,000
Monthly rate = 5% / 12 = 0.4167%
Number of payments = 5 × 12 = 60
Monthly payment = $400,000 [ (0.004167)(1.004167)^60 ] / [ (1.004167)^60 - 1 ] ≈ $8,216.50
Total interest = ($8,216.50 × 60) - $400,000 ≈ $375,990

This example shows that with these terms, you would pay approximately $8,216.50 per month with $375,990 in total interest over the 5-year term.

Frequently Asked Questions

What is the difference between fixed and variable rates?

A fixed-rate mortgage has the same interest rate for the entire loan term, while a variable rate mortgage can change based on market conditions. Fixed rates typically offer more stability, while variable rates may offer lower initial rates.

How does the amortization period affect my payment?

A longer amortization period (e.g., 25 years) results in lower monthly payments but more total interest paid. A shorter period (e.g., 5 years) has higher monthly payments but less total interest.

What is the difference between principal and interest payments?

Principal payments reduce the outstanding loan balance, while interest payments cover the cost of borrowing. Early in the loan term, most payments go toward interest, while later payments focus more on principal.
