Home Affordability Calculator
Translate a monthly housing budget into a more realistic home price target before you start shopping seriously.
Calculator
Home Affordability Calculator
Use the all-in monthly payment you want to stay under.
Add one or more gross monthly income sources if you want affordability checked against household income and debt ratios.
Total gross income: $0.00
Add recurring non-housing debts if you want a back-end debt-to-income check alongside the home-price estimate.
Other monthly debts: $0.00
Enter the cash you expect to put toward the purchase.
Use the annual mortgage rate you want to test.
A 30-year term is common for affordability planning.
Enter the approximate annual property tax as a percentage of home value.
Add an annual homeowner's insurance estimate.
Use zero if PMI would not apply. Enter the annual PMI rate as a percent of the loan amount.
Set this to zero if the home would not have HOA dues.
Add recurring housing costs that should count against the same monthly budget, such as maintenance reserves or condo fees outside HOA.
Other housing cost total: $0.00
Use the expected closing costs as a percentage of the purchase price if you want a cash-to-close estimate.
Example values are loaded.

Borrowing
Mortgage Calculator
Estimate monthly mortgage payments with principal, interest, taxes, insurance, PMI, HOA, and other recurring housing costs included.
Borrowing
Down Payment Calculator
Calculate the dollar amount of a home down payment, cash to close, resulting loan size, and estimated monthly housing cost.
Savings
Down Payment Savings Calculator
Calculate how long it could take to fully fund down payment savings with your current balance, monthly savings, and expected growth.
What this calculator shows
A housing budget should account for more than principal and interest because taxes, insurance, HOA dues, and sometimes PMI change the real monthly cost.
It works backward from a target monthly budget so you can set a search range before you get serious about shopping, while still leaving room for other recurring housing costs and estimated closing cash.
How to use it
- 1. Enter the monthly housing payment you want to stay under.
- 2. Optionally add household income and other debts if you want the result checked against common debt-to-income limits.
- 3. Add the down payment, mortgage rate, loan term, taxes, insurance, optional PMI, HOA, other recurring housing costs, and optional closing-cost rate so the affordability number stays realistic.
Formula and assumptions
The calculator estimates the portion of the monthly budget available for principal and interest after taxes, insurance, optional PMI, HOA, and any other monthly housing costs.
It then solves for the loan amount that fits that payment and adds the down payment back to estimate the total home price, while separately estimating cash needed at close if a closing-cost rate is provided.
How to read this result
Treat the estimated home price as a planning ceiling, not a target you must spend to. Leaving room below the maximum usually protects the rest of the household budget better.
If household income and other debts are entered, compare the debt ratios with the home price estimate. A house that fits the payment can still push the overall borrowing profile too hard.
Use this result to shape your shopping range first, then move into mortgage and down-payment scenarios once you know the search band is realistic.
Common mistakes
Using a monthly budget that only covers principal and interest. Affordability works better when taxes, insurance, HOA, PMI, and other recurring housing costs stay in the number.
Assuming the full estimated price should become the listing search cap. Buyers usually need room for maintenance, moving costs, and normal budget volatility too.
Ignoring cash-to-close. A monthly budget may support the payment while the upfront cash requirement still makes the purchase unrealistic.
Notes
This estimate still does not include utilities or one-time move costs.
Worked example
A $2,800 monthly budget with taxes and insurance included is a useful way to avoid over-shopping early in the process.

FAQ
FAQ
Why do taxes and insurance reduce affordability so much?
Because those costs use part of the same monthly budget that would otherwise be available for principal and interest.
FAQ
Can I include household income and other debts?
Yes. Add income and debt rows if you want the calculator to show front-end and back-end debt-to-income ratios alongside the budget-based estimate.
FAQ
Does this mean I should spend the full amount it shows?
Not necessarily. Many buyers leave extra room for maintenance, repairs, utilities, and changing rates.
