Understanding Mortgage Calculation Formula
The mortgage calculator uses a standard EMI formula used by banks and financial institutions.
Monthly Mortgage Payment Formula:
EMI=(1+r)n−1P×r×(1+r)n
Where:
- P = Loan Amount (Principal)
- r = Monthly Interest Rate (Annual Rate ÷ 12 ÷ 100)
- n = Total Number of Months (Years × 12)
Explanation of Formula
1. Loan Amount (P)
This is the base amount borrowed from the lender.
2. Interest Rate (r)
Annual interest is divided by 12 to get the monthly rate.
3. Loan Term (n)
Total number of monthly payments over the loan duration.
What the Calculator Displays
After calculation, the tool provides three key outputs:
1. Monthly Payment
The fixed amount you pay every month.
2. Total Payment
The total amount paid over the entire loan period.
3. Total Interest
The extra cost paid to the lender beyond the principal.
