Plan your home purchase with confidence. Calculate monthly payments, see how much house you can afford, and understand the true cost of your loan.
Buying a home is the biggest financial decision most people ever make. Our mortgage calculators help you avoid expensive surprises by showing exactly what your loan will cost — month by month, year by year, and over the full term. Every tool here uses the same standardized formulas that banks and lenders use, so the numbers you see are the numbers you'll actually pay.
Calculate your monthly mortgage payment including principal, interest, property taxes, home insurance, and PMI. See your full amortization schedule.

Home BuyersWalking into a lender's office without knowing your numbers is like going grocery shopping without checking your bank balance. A mortgage calculator gives you the answers before a loan officer starts pitching products. You'll know exactly what monthly payment you can handle, how much down payment makes sense, and which loan terms actually fit your budget.
This is especially important because mortgages are designed to look smaller than they really are. A "$300,000 loan at 7% for 30 years" sounds manageable — until you realize you'll pay over $418,000 in interest alone, more than the price of the house itself. Our tools surface these hidden costs so there are no surprises three years into the loan.
Your monthly mortgage payment isn't just the loan repayment. Most lenders bundle four costs together — collectively called PITI:
If your down payment is less than 20%, you'll also pay PMI (Private Mortgage Insurance) until you build enough equity. Our payment calculator includes all of these so you see your real monthly cost — not just the loan portion.
Our calculators give accurate mathematical results, but they don't replace a real mortgage pre-approval. Lenders consider factors we can't — credit score nuances, employment stability, debt history, and underwriting policies that vary by bank. Use these tools to plan and compare scenarios, then talk to a licensed mortgage professional before making offers on a home.
The payment calculator works backward from a loan amount — you enter the home price, down payment, rate, and term, and it tells you the monthly payment. The affordability calculator works the other way — you enter your income, debts, and down payment, and it tells you what home price you can afford. Most buyers should use the affordability tool first, then the payment tool to fine-tune their target price.
The math (loan amortization formula) is universal — it works for mortgages anywhere in the world. However, defaults like property tax rates, PMI thresholds, and the 28/36 affordability rule are based on US norms. Buyers in the UK, Canada, Australia, or elsewhere can still use the tools by entering their local property tax rate and ignoring PMI if it doesn't apply in their country.
We suggest a starting rate based on recent market averages, but rates change daily. For the most accurate calculation, get a quote from your bank or mortgage broker and enter that rate. Even a 0.25% difference in rate can change your monthly payment by $50–$100 on an average loan.

Property tax, insurance, maintenance and any service charges sit outside a principal-and-interest figure, which is a common reason the first year of ownership feels tighter than expected. Our affordability calculator works from income and existing debts rather than from the payment alone.

Back to HomepageMortgage planning splits into two distinct questions that are often confused. The first is what a given loan would cost each month. The second, and more important, is how much you can sensibly borrow given your income and other commitments. A lender's maximum and a comfortable amount are frequently different numbers.
Lenders assess affordability using debt-to-income ratios, but those ratios do not know about your circumstances, your job security, or what you want your life to look like. Borrowing the maximum offered is a decision, not a default.
| Component | What It Covers | Varies With |
|---|---|---|
| Principal | Repayment of the amount borrowed | Loan size and term |
| Interest | Cost of borrowing | Rate and outstanding balance |
| Property tax | Local authority charges | Location and assessed value |
| Insurance | Buildings and contents cover | Property and provider |
| Mortgage insurance | Applies below certain deposit levels | Deposit size and loan type |
Property tax, insurance, maintenance and service charges are ongoing costs that a principal-and-interest calculation excludes. Budgeting only for the mortgage payment is a common reason new owners find the first year tighter than expected.
