Mortgage Calculation Formula Explained
This calculator uses a standard financial formula used by banks worldwide to calculate fixed-rate loan payments.
Monthly Payment Formula:
M=(1+r)n−1P×r×(1+r)n
Where:
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Understanding the Formula in Simple Terms
Let’s break it down:
- The loan amount (P) is what you borrow.
- The interest rate (r) is what the bank charges monthly.
- The loan term (n) is how many months you will pay.
The formula calculates how the loan is spread evenly across all months while including interest.
Example Calculation
Let’s say:
- Loan Amount = $200,000
- Interest Rate = 5% per year
- Loan Term = 20 years
Step 1: Convert values
- Monthly interest rate = 5 ÷ 12 ÷ 100 = 0.004167
- Total months = 20 × 12 = 240
Step 2: Results
| Description | Amount (Approx.) |
|---|---|
| Monthly Payment | $1,319.91 |
| Total Payment | $316,778.40 |
