How Does a House Loan Calculator Work?
The calculator uses a standard mortgage repayment formula to estimate equal monthly payments over the loan period.
Required Inputs
1. Loan Amount
This is the amount borrowed from the lender after subtracting the down payment.
Example:
- House price: $500,000
- Down payment: $100,000
- Loan amount: $400,000
2. Interest Rate
The annual percentage charged by the lender for borrowing money.
Example:
- 5% annual interest rate
3. Loan Term
The number of years chosen to repay the mortgage.
Common repayment terms include:

Formula Used in House Loan Calculations
The House Loan Calculator uses the standard amortization formula:
M=P×(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Loan principal
- r = Monthly interest rate
- n = Total number of monthly payments
This formula calculates equal monthly mortgage payments throughout the loan term.
Example of a House Loan Calculation
Suppose a buyer takes a house loan with the following details:
- Loan amount: $300,000
- Interest rate: 4.5%
- Loan term: 30 years
Estimated Results
- Monthly payment: Approximately $1,520
- Total repayment: Approximately $547,200
- Total interest paid: Approximately $247,200
This example highlights how interest accumulates significantly over long repayment periods.
