What Is a Mortgage Loan?
A mortgage loan is a long-term loan used to purchase a home or other real estate property. The lender provides the funds needed to buy the property, and the borrower repays the loan over an agreed period with interest.
Mortgage payments usually consist of:
- Principal (the amount borrowed)
- Interest (the cost of borrowing)
- Taxes (if applicable)
- Insurance (if applicable)
This calculator focuses on calculating the principal and interest repayment based on your loan details.

Mortgage Repayment Formula
The calculator uses the standard mortgage amortization formula.
Formula:
M = P × [r(1+r)^n] ÷ [(1+r)^n − 1]
Where:
- M = Payment per period
- P = Loan amount
- r = Interest rate per payment period
- n = Total number of payments
The periodic interest rate is calculated as:
Annual Interest Rate ÷ Payment Frequency
The total number of payments equals:
Loan Term × Payment Frequency
This formula ensures each payment includes both principal and interest.
Mortgage Calculation Example
Suppose you borrow:
- Loan Amount = $300,000
- Interest Rate = 6%
- Loan Term = 30 years
- Payment Frequency = Monthly
The calculator estimates:
- Monthly Payment ≈ $1,799
- Total Payments ≈ $647,640
- Total Interest ≈ $347,640
- Number of Payments = 360
These values are estimates and may vary slightly depending on lender-specific calculations.
