Mortgage Calculator
Mortgage Calculator
Calculate your estimated monthly mortgage payment, total interest, and total loan cost.
Mortgage Calculator
Our Mortgage Calculator is a simple online tool designed to help you estimate your monthly mortgage payment based on the loan amount, annual interest rate, and loan term. Whether you are considering buying a home, comparing different loan options, or simply planning your monthly budget, this calculator can provide a quick estimate of the cost of a fixed-rate mortgage.
The calculator also shows the estimated total interest paid over the life of the loan, total amount paid, principal amount, and number of monthly payments. You can select from several common currency symbols, including USD, BDT, GBP, EUR, and INR.
What Is a Mortgage?
A mortgage is a type of loan commonly used to finance the purchase of a house or other real estate. The borrower receives money from a lender and agrees to repay the loan over a specified period, usually through regular monthly payments.
A typical mortgage payment may include repayment of the original amount borrowed, known as the principal, as well as interest charged by the lender. Depending on the mortgage and location, the actual monthly housing payment may also include taxes, insurance, mortgage insurance, association fees, and other costs.
How Does the Mortgage Calculator Work?
This calculator uses the standard amortizing loan formula to estimate the monthly principal and interest payment for a fixed-rate loan. To perform the calculation, enter the total loan amount, annual interest rate, and loan term in years.
After entering the required information, click the Calculate Mortgage button. The calculator will instantly estimate your monthly payment and display a summary of the loan.
What Is the Loan Amount?
The loan amount is the amount of money you borrow from the lender. It is not necessarily the same as the purchase price of the property. For example, if a home costs $300,000 and you make a $60,000 down payment, the mortgage principal before other financed costs would generally be $240,000.
When using this calculator, enter the amount you expect to borrow rather than the total property price if a down payment has already been deducted.
What Is the Mortgage Interest Rate?
The mortgage interest rate represents the cost of borrowing money and is generally expressed as an annual percentage. A higher interest rate usually results in a higher monthly payment and a larger total amount of interest paid over the life of the loan.
Even relatively small differences in interest rates can affect the total cost of a long-term mortgage, so comparing different loan scenarios can be useful when evaluating financing options.
What Is a Mortgage Loan Term?
The loan term is the length of time scheduled for repayment of the mortgage. Common mortgage terms may include 10, 15, 20, or 30 years, although available terms vary by lender and country.
A longer loan term can reduce the required monthly principal and interest payment, but it can also result in more interest being paid over the life of the loan. A shorter term generally requires larger monthly payments while reducing the number of payments.
How Is the Monthly Mortgage Payment Calculated?
For a standard fixed-rate amortizing mortgage, the monthly payment is calculated using the principal amount, monthly interest rate, and total number of monthly payments.
M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
In this formula, M represents the monthly payment, P represents the principal loan amount, r represents the monthly interest rate, and n represents the total number of monthly payments.
What Is Total Interest?
Total interest is the estimated amount paid to the lender above the original principal over the full loan term, assuming the scheduled payments are made and the interest rate remains fixed. The calculator estimates total interest by subtracting the original principal from the total of all scheduled monthly payments.
Why Use a Mortgage Calculator?
A mortgage calculator can help you understand how different loan amounts, interest rates, and repayment terms may affect monthly payments. You can change the numbers and calculate multiple scenarios to compare how the estimated cost changes.
This can be useful for preliminary budgeting before speaking with a lender. However, a calculator cannot determine whether you qualify for a particular mortgage or what rate and terms a lender will offer.
Does This Calculator Include Taxes and Insurance?
No. The monthly payment shown by this calculator represents an estimate of principal and interest only. It does not automatically include property taxes, homeowners insurance, private mortgage insurance, homeowners association fees, closing costs, lender fees, or other expenses.
Your actual monthly housing payment can therefore be higher than the amount displayed by this calculator.

4. Does the calculator include homeowners insurance?
No. Homeowners insurance, mortgage insurance, association fees, and other additional costs are not included.
5. What is mortgage principal?

6. What is mortgage interest?
Mortgage interest is the cost charged by a lender for borrowing money. The interest rate is commonly expressed as an annual percentage.
7. What happens if the interest rate is 0%?
If the interest rate is 0%, the calculator divides the principal by the total number of monthly payments. In that case, the total interest is zero.
8. Is a longer mortgage term better?
A longer term generally reduces the required monthly principal and interest payment but can increase the total interest paid. A shorter term generally results in higher monthly payments but fewer payments overall. Which structure is appropriate depends on the borrower's circumstances and loan terms.
9. Is the calculated mortgage payment exact?
No. The result is an estimate. Actual payments can differ because of lender terms, fees, taxes, insurance, mortgage insurance, and other costs.
