How to Use This Mortgage Calculator
Our free mortgage calculator makes it easy to estimate your monthly home loan payment in seconds. Simply enter your loan details below and get an instant breakdown of your principal, interest, and total payment.
To calculate your mortgage payment, you’ll need three key pieces of information: the loan amount (how much you’re borrowing), the annual interest rate your lender offers, and the loan term (typically 15 or 30 years).
What is a Mortgage Payment Made Of?
Your monthly mortgage payment typically consists of four components, often referred to as PITI:
- Principal: The portion that reduces your actual loan balance
- Interest: The cost charged by the lender for borrowing money
- Taxes: Property taxes collected monthly and held in escrow
- Insurance: Homeowner’s insurance (and PMI if down payment is under 20%)
Our calculator focuses on the principal and interest portion. Add estimated taxes and insurance for a complete picture of your monthly housing cost.
Mortgage Payment Formula
The standard formula lenders use to calculate a fixed-rate mortgage payment is:
M = P × [r(1+r)ⁿ] / [(1+r)ⁿ – 1]
- M = Monthly payment
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of payments (years × 12)
Example: $300,000 Home Loan at 7% for 30 Years
| Detail | Amount |
|---|---|
| Home Price | $375,000 |
| Down Payment (20%) | $75,000 |
| Loan Amount | $300,000 |
| Interest Rate | 7.00% |
| Loan Term | 30 years |
| Monthly Payment (P&I) | $1,996 |
| Total Interest Paid | $418,527 |
| Total Amount Paid | $718,527 |
15-Year vs 30-Year Mortgage: Which Should You Choose?
| Feature | 15-Year Mortgage | 30-Year Mortgage |
|---|---|---|
| Monthly Payment | Higher | Lower |
| Total Interest Paid | Much less | Much more |
| Build equity | Faster | Slower |
| Best for | Higher income, want to save | More monthly cash flow |
For most first-time buyers, a 30-year mortgage offers the flexibility of lower monthly payments. If you can comfortably afford a higher payment, a 15-year loan saves tens of thousands in interest over the life of the loan.

Frequently Asked Questions
Most conventional loans require a minimum credit score of 620. However, to qualify for the best interest rates, you’ll want a score of 740 or higher. FHA loans may accept scores as low as 580 with a 3.5% down payment.
The general rule is to keep your mortgage payment below 28% of your gross monthly income. Some lenders allow up to 36% when including all debts. This is called the debt-to-income (DTI) ratio and is a key factor lenders evaluate.
Yes. Making extra principal payments reduces your loan balance faster and saves a significant amount in interest. Even one extra payment per year on a 30-year mortgage can cut 4–5 years off your loan term. Check with your lender about prepayment penalties before doing so.
Private Mortgage Insurance (PMI) is required when your down payment is less than 20% on a conventional loan. It typically costs 0.5%–1.5% of the loan amount annually. You can avoid PMI by putting down 20% or more, or by requesting cancellation once you reach 20% equity in your home.
Mortgage rates in 2026 remain influenced by Federal Reserve policy and inflation. Rates have shown some easing compared to 2023–2024 peaks. It’s best to compare current offers from multiple lenders rather than trying to time the market. Use our mortgage calculator above to see how different rates affect your monthly payment.
