Home Price from Monthly Budget Calculator
Work backward from the monthly housing payment you can afford to the home price it buys — accounting for down payment, rate, taxes and insurance.
How it works
Price = budget ÷ [(1 − down%) × mf + tax&ins monthly], where mf = i ÷ (1 − (1 + i)⁻ⁿ), i = rate ÷ 12
This reverses the usual mortgage calculation: instead of a price giving a payment, a payment gives a price. The trick is that taxes and insurance scale with the home price, so both the loan payment and the escrow are expressed per dollar of price and added together, then the budget is divided by that combined factor. A bigger down payment lowers the loan share and lifts the price your payment supports.
Worked example
A $2,500/mo budget at 6.5% over 30 years with 20% down: the mortgage factor is about 0.006321 per dollar of loan, 80% of price is financed, and 1.5% ÷ 12 = 0.00125 covers tax and insurance. Combined that is 0.8 × 0.006321 + 0.00125 ≈ 0.006307 per dollar, so price ≈ 2,500 ÷ 0.006307 ≈ $396,400, needing about $79,300 down.
Frequently asked questions
Why does the down payment raise the price I can afford?
Only the financed portion carries a mortgage payment. Putting more down shrinks the loan per dollar of price, so more of your fixed budget can support a higher purchase price — though you need the cash up front.
Does this include PMI or HOA dues?
No. It covers principal, interest, property tax and homeowners insurance. Private mortgage insurance (common below 20% down) and HOA dues would reduce the price your budget supports, so treat this as an optimistic ceiling.
How is this different from an affordability calculator?
Affordability tools start from income and a DTI limit. This one starts from the exact monthly payment you are comfortable with and translates it into a price — useful when you already know your comfortable payment.
