Mortgage Calculation Formula Explained
The calculator uses the standard mortgage amortization formula to compute monthly payments.
Monthly Mortgage Payment Formula
M=1−(1+r)−nP⋅r
Where:
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Step-by-Step Breakdown
1. Convert Annual Rate to Monthly Rate
r=12×100R
Where:
- R = annual interest rate
2. Calculate Total Payments
n=years×12
3. Apply Mortgage Formula
Substitute values into the main formula to get monthly payment.
Example Mortgage Comparison
Let’s understand with a real example.
Mortgage 1
- Loan: $300,000
- Interest Rate: 5%
- Term: 30 years
Mortgage 2
- Loan: $280,000
- Interest Rate: 4.5%
- Term: 25 years
Results Table
| Mortgage | Monthly Payment | Total Term | Cost Level |
|---|---|---|---|
| Mortgage 1 | $1,610.46 | 30 Years | Higher long-term interest |
| Mortgage 2 | $1,555.20 | 25 Years | Lower total interest |
| Difference | $55.26 | — | Savings with Mortgage 2 |
Better Option
In this example, Mortgage 2 is better because it offers:
- Lower monthly payment difference
- Shorter loan term
- Reduced total interest cost
Why Mortgage Comparison Matters
Choosing a mortgage without comparison can lead to long-term financial loss. Even a 0.5% difference in interest rate can significantly impact total repayment.
Example Impact of Interest Rate Difference
| Interest Rate | Monthly Payment (Approx) |
|---|---|
| 4% | Lower payment |
| 5% | Higher payment |
| 6% | Much higher payment |
Small changes = big financial difference over time.
