Mortgage Payment Formula
The standard formula for calculating the fixed monthly payment (M) of a loan is:
M = P * [ i * (1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
- M = Monthly Payment
- P = Principal Loan Amount
- i = Monthly Interest Rate (Annual Rate / 12)
- n = Total Number of Payments (Loan Term in Years * 12)
Variables Explained
- Principal Loan Amount: The initial amount borrowed from the lender. This is the starting balance used for the mortgage calculation.
- Annual Interest Rate: The nominal yearly rate charged by the lender, expressed as a percentage. This rate is divided by 12 to get the monthly rate (i).
- Loan Term (Years): The total duration (in years) over which the loan will be repaid (e.g., 15 years, 30 years). This determines the total number of payments (n).

What is a Mortgage Calculator?
A mortgage calculator is an essential online tool that allows prospective and current homeowners to estimate their monthly housing payments based on the terms of their loan. By inputting the loan’s principal amount, the annual interest rate, and the repayment term, users receive an immediate estimate of the required monthly commitment. This tool is fundamental in financial planning, helping users determine affordability and budget effectively for one of the largest financial decisions they will make.
Beyond just the monthly payment, advanced mortgage calculators, like this one, provide a detailed amortization schedule. This schedule breaks down each payment into its interest and principal components over the life of the loan. Understanding this breakdown is crucial because in the early years of a loan, a larger portion of the payment goes toward interest, while later years see the bulk of the payment dedicated to reducing the principal.
How to Calculate Monthly Payments (Example)
Let’s use an example: $250,000 Principal, 6% Annual Rate, 30-Year Term.
- Determine the Monthly Rate ($i$): Divide the annual rate by 12. ($6\% / 12 = 0.5\%$ or $0.005$ as a decimal).
- Determine Total Payments ($n$): Multiply the loan term by 12. ($30 \text{ years} \times 12 = 360 \text{ payments}$).
- Apply the Formula: Substitute the values into $M = P \times [ i \times (1 + i)^n ] / [ (1 + i)^n – 1 ]$.
- Solve the Exponent: Calculate $(1 + 0.005)^{360} \approx 6.022575$.
- Calculate the Numerator: $P \times i \times (\text{Power Factor}) = 250,000 \times 0.005 \times 6.022575 \approx 7528.21875$.
- Calculate the Denominator: $(\text{Power Factor}) – 1 = 6.022575 – 1 = 5.022575$.
- Final Payment ($M$): Numerator / Denominator $\approx 7528.21875 / 5.022575 \approx 1500.07$. The monthly payment is approximately $1,500.07.
Frequently Asked Questions (FAQ)
- How does the Annual Interest Rate affect the monthly payment? The interest rate is a key determinant. A higher rate means a larger portion of your monthly payment goes toward interest, significantly increasing the total cost of the loan over its life. Even a small change in the rate can impact the payment by hundreds of dollars.
- Is a 15-year or 30-year term better? A **15-year mortgage** results in much lower total interest paid and a faster path to ownership, but the **monthly payments** will be significantly higher. A **30-year mortgage** offers lower monthly payments, providing better cash flow, but you pay substantially more interest over the loan’s lifetime.
- What is PITI? PITI stands for **Principal, Interest, Taxes, and Insurance**. While this calculator estimates the Principal and Interest (P&I) portion of your payment, your final monthly cost will include escrowed amounts for Property Taxes and Homeowner’s Insurance (T&I).
- Can I calculate the total interest paid with this tool? Yes. Once the monthly payment is calculated, the tool determines the total payments ($M \times n$) and subtracts the original principal ($P$). The remainder is the total interest paid over the life of the loan.
