Monthly Mortgage Calculator 🏡
Plan your future home ownership with precision and clarity.
The Mortgage Calculation Formula
This is the standard formula used to calculate the fixed monthly payment (M) for a mortgage.
Detailed Formula Explanation
The formula to calculate your monthly mortgage payment is a cornerstone of financial mathematics. Understanding its components can give you a clearer picture of where your money is going.
- M = Monthly Payment: This is the fixed amount you will pay each month for the duration of the loan.
- P = Principal Loan Amount: This is the initial amount of money you borrowed from the lender.
- r = Monthly Interest Rate: This is your annual interest rate divided by 12. For example, a 6% annual rate becomes a 0.005 monthly rate (0.06 / 12). The calculation must use the decimal form of the rate.
- n = Number of Payments: This is the total number of payments you will make over the life of the loan. It’s calculated by multiplying your loan term in years by 12 (e.g., a 30-year loan has 360 payments).
The numerator, P[r(1+r)^n], calculates the payment amount as if it were an interest-only loan, but adjusted for the compounding effect over the loan’s life. The denominator, [(1+r)^n – 1], is a factor that accounts for the amortization, spreading the principal repayment over the entire term. Together, they ensure that each fixed payment correctly allocates a portion to both interest and principal, resulting in the loan balance reaching zero after the final payment.

5. FAQs
Q1: What is amortization?
A: Amortization is the process of spreading out a loan into a series of fixed payments over time. Each payment consists of both principal and interest. While the payment amount stays the same, the proportion of principal and interest changes with each payment. In the beginning, a larger portion of your payment goes to interest. Over time, as your loan balance decreases, more of your payment goes towards paying down the principal.
Q2: Does this calculator include taxes and insurance (PITI)?
A: This calculator focuses on the principal and interest (P&I) components of your mortgage payment, which is the core of the loan itself. It does not include property taxes, homeowners’ insurance, or private mortgage insurance (PMI), which are often bundled into the total monthly payment by lenders. These additional costs can vary significantly based on your location, property value, and down payment size.
Q3: How can a shorter loan term benefit me?
A: A shorter loan term (e.g., 15 years instead of 30) typically comes with a higher monthly payment, but it can save you a substantial amount of money in total interest over the life of the loan. You also build equity in your home much faster. Our comparison feature can help you visualize these savings directly.
Q4: What is the difference between interest rate and APR?
A: The interest rate is the cost of borrowing the principal loan amount, expressed as a percentage. The Annual Percentage Rate (APR) is a broader measure of the cost of your loan. It includes the interest rate plus other charges and fees, such as lender fees, closing costs, and mortgage insurance. The APR is usually slightly higher than the interest rate and gives a more complete picture of the loan’s total cost.
Q5: Can I make extra payments to pay off my mortgage faster?
A: Yes, in most cases. Making extra payments that are applied directly to your principal balance can help you pay off your mortgage faster and save a significant amount on interest. You can make a larger monthly payment, make one extra payment per year, or make bi-weekly payments. It’s important to check with your lender first to ensure there are no prepayment penalties and that extra funds are correctly applied to the principal.
