See the monthly pieces of a home purchase
Enter your own figures for a fixed-rate, fully amortizing mortgage. The calculator separates principal and interest, a monthly tax and property-insurance estimate, mortgage insurance, HOA dues, and optional maintenance savings. No email address or account is required.
This is a budgeting worksheet, not a mortgage offer, insurance quote, affordability approval, or recommendation to buy. It does not fetch rates or predict future costs. For the wider comparison, read renting versus buying: the housing costs to compare.
Enter numbers without commas or currency signs. Dollar fields accept up to two decimal places. Required fields start blank. Optional fields left blank are not included in the totals; a blank does not establish that no cost applies. Enter 0 only when you deliberately want a zero-cost assumption.
JavaScript is needed to calculate. The explanation and manual planning steps below remain available.
Your monthly planning estimate
This breakdown uses the figures entered. The monthly tax and property-insurance subtotal divides annual amounts by 12. It is not your lender's actual escrow collection, and the totals do not include all the costs of owning a home. Figures are rounded for display after calculation, so displayed line items can differ from totals by a few cents. The rental comparison subtracts the two displayed totals, rounded to cents.
| Item | Amount or note |
|---|
Excluded: closing and transaction costs, initial escrow deposits, prepaid expenses, utilities, special assessments, tax effects, opportunity cost, and optional costs not entered. The comparison does not value equity or forecast property appreciation, future rent, taxes, premiums, or repairs.

Use Clear all figures to remove visible entries when finished. A fresh page load starts blank; a browser may retain a page in its back-navigation memory. Clearing this tool does not remove a saved file or printout.
What does the escrow estimate mean?
A mortgage escrow account commonly holds money for property taxes and insurance bills. Whether one is required, which bills it covers, and how much is collected depend on the loan and lender. If you pay those bills directly, they still belong in your housing budget.
This worksheet uses annual property taxes plus annual homeowners insurance plus any separate property-insurance premium you enter, divided by 12. It does not calculate a lender's escrow cushion, a shortage repayment, the initial escrow deposit at closing, or changes in bill timing. Ask the lender for its actual projected payment and escrow analysis. A fixed loan interest rate does not keep taxes or insurance premiums fixed.
Mortgage insurance is a separate line because it is different from insurance protecting the home. This tool neither decides whether you need it nor estimates when it ends. Confirm its amount, duration, and collection method with the lender. HOA dues and maintenance savings are separate from the lender escrow estimate here. Your actual loan documents identify what is escrowed and what you pay yourself.
Where should you get the inputs?
- Use the purchase price and the down payment you are evaluating. The estimated loan is price minus down payment. Financed fees, secondary loans, and other adjustments are not included.
- Use the annual loan interest rate from the lender's loan terms. APR includes other borrowing costs and is not the rate used for this payment calculation.
- Research the tax treatment for the prospective purchase with the relevant tax authority. Confirm exemptions, assessments, and whether a purchase can change the taxable amount.
- Request a property-specific insurance estimate. Check which separate coverage may be needed, then avoid counting the same premium twice.
- Obtain HOA dues and any known special assessments from the actual association documents. This tool models recurring dues only; budget special assessments separately.
- Choose a maintenance savings amount that reflects your own planning. A smooth monthly reserve does not mean repair bills will arrive evenly or that the reserve will be sufficient.
How the loan payment is calculated
Let L be the estimated loan amount, r the annual interest percentage divided by 1,200, and n the selected years multiplied by 12. The monthly principal-and-interest payment is L × r ÷ [1 − (1 + r)−n]. At an interest rate of zero, it is L ÷ n. The calculation assumes equal monthly payments on a fully amortizing fixed-rate loan, with no extra payments.
The loan, tax, and insurance planning subtotal adds principal and interest, the monthly tax and property-insurance estimate, and entered mortgage insurance. The monthly payment budget adds entered HOA dues. The broader budget then adds your maintenance reserve. These labels describe this worksheet's arithmetic; they do not replace the lender's definitions or disclosures.
Compare carefully with your rental budget
The optional comparison subtracts the rent, renters insurance, and required recurring rental fees you enter from the broader ownership budget. Add recurring fees separately only when they are not already part of your rent or insurance amount. A positive difference means the selected ownership outlays are higher. A negative difference means they are lower. Either result is incomplete without the costs and tradeoffs omitted above. A principal repayment builds ownership equity, and a maintenance reserve is savings until used; neither is equivalent to rent expense.
Keep your current coverage planning separate from this exercise. Use the renters insurance cost guide to understand premium comparisons and the renters quote worksheet to compare policy terms. The renters insurance checklist and belongings inventory calculator can help organize your possessions while you rent and prepare for a future move. Do not cancel a current policy based on this calculator.
