How Much House Can I Afford by Monthly Payment?
The home price you can afford depends on the monthly payment you can sustain, not the other way around. Starting from your budget and working backward through interest rate, property taxes, insurance, and any PMI produces a realistic ceiling that accounts for every component of PITI. Enter your target payment above to find that number.
Your budget

- Home insurance

- PMI

- HOA dues

This works backwards from the payment you named. It says nothing about whether a lender will approve you — for that, start from income and debts instead.
Working the Math in Reverse
Most mortgage calculators start with a home price and output a payment. This tool reverses the equation: given the monthly amount you can commit to housing, it solves for the maximum loan and corresponding home price after subtracting estimated taxes, insurance, and PMI from your budget.
The order matters because small changes in non-principal components eat into purchasing power quickly. A monthly property-tax estimate of $400 versus $250 removes $150 from the portion available for principal and interest, which at an illustrative 7 percent rate translates to roughly $22,500 less in borrowing capacity. Insurance and PMI apply the same downward pressure.
That is why this approach tends to produce more grounded expectations than the traditional affordability formula. You anchor on the number that shapes your daily life — the payment — rather than discovering it after falling in love with a list price.
What Shapes the Price You Can Reach
Interest rate is the largest lever. At an illustrative 6 percent, a $2,000 monthly principal-and-interest budget supports a loan of approximately $333,600. At 8 percent, the same $2,000 supports only about $272,600 — a gap of more than $60,000 from rate alone, before taxes and insurance even enter the picture.
The down payment determines how much home that loan amount buys. A $333,600 loan with 10 percent down implies a home near $370,700. With 20 percent down, the same loan reaches approximately $417,000 and eliminates PMI entirely — which feeds a few more dollars back into the principal-and-interest slice.
Because so many inputs interact, a single rule like "three times your income" misses too much. Use this calculator to model your specific comfort level, then cross-check with the income-based affordability tool and the DTI calculator to confirm the result sits within conventional lending guidelines.
