Mortgage Calculation Formula Explained
The calculator uses a standard mortgage formula used by banks and financial institutions worldwide.
Monthly Mortgage 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 months (years × 12)
What Each Term Means
1. Principal (Loan Amount)
This is the total amount borrowed from the bank or lender.
2. Interest Rate
The percentage charged by the lender for borrowing money.
3. Loan Term
The number of years you will take to repay the loan.
4. Monthly Payment
The fixed amount you pay every month.
Example Calculation (Real-Life Scenario)
Let’s understand how the calculator works with a real example:
Input Values:
- Loan Amount = $170,000
- Interest Rate = 5%
- Loan Term = 30 years
Step-by-Step Result:
| Metric | Value |
|---|---|
| Monthly Payment | $912.48 |
| Total Payment | $328,492.80 |
| Total Interest | $158,492.80 |
Explanation:
- You borrow $170,000
- Over 30 years, you pay $912.48 monthly
- Total interest paid is higher than the loan itself
This shows how long-term loans significantly increase total cost due to interest.
