What is the Mortgage Calculator?
Estimate your monthly mortgage payment including property tax, from the price, deposit, rate and term. People often search for it as "mortgage calculator", "home loan calculator" or "monthly mortgage payment". This free version works on any phone or computer and needs no download.
How to use the Mortgage Calculator
- Open the Mortgage Calculator.
- Enter your values in the fields.
- The results update instantly as you type.
- Note or copy the numbers you need.
How it works
The loan is the home price minus your down payment. The monthly principal and interest uses the standard loan formula, and the property tax is the annual rate times the price divided by 12. The tool adds them for your total monthly payment. Insurance, HOA fees and closing costs are not included.
Worked example
- Input: Home price: 300000; Down payment (%): 20; Annual interest rate (%): 6.5; Term (years): 30; Property tax per year (% of price): 1.2
- Result: Loan amount: 240,000.00; Principal and interest: 1,516.96; Property tax per month: 300.00; Total monthly payment: 1,816.96; Total interest over the term: 306,106.77
Common uses
- Work out what home price fits your monthly budget
- See how a bigger down payment lowers the payment
- Compare a 15 year and a 30 year mortgage
Second worked example
Here is the same tool with larger numbers, so you can see how the result scales.
- Input: Home price: 450000; Down payment (%): 20; Annual interest rate (%): 6.5; Term (years): 30; Property tax per year (% of price): 1.2
- Result: Loan amount: 360,000.00; Principal and interest: 2,275.44; Property tax per month: 450.00; Total monthly payment: 2,725.44; Total interest over the term: 459,160.16
Tips for the best result
- Use the rate exactly as your bank or lender quotes it, and check whether it is a yearly or a monthly rate.
- Run two or three scenarios, such as a higher and a lower rate, to see the range of outcomes.
- Add fees, insurance and taxes separately, because many calculators leave them out.
- Round only at the end so small differences do not add up.
Common mistakes to avoid
- Typing a monthly rate where a yearly rate is expected, which makes the answer far too small.
- Mixing years and months in the term field.
- Treating the result as a promise. Real rates, fees and taxes change over time.
- Forgetting that taxes and charges differ from country to country.
