Our affordability calculator determines the maximum home price you can afford using the standard amortization formula solved for principal.
In this equation, P is the maximum principal loan amount. M is the monthly payment allocated to principal and interest. r is the monthly interest rate (annual rate divided by 12). n is the total number of payments (loan term in years multiplied by 12). To find the maximum purchase price, add your available down payment to P.

The calculator gives you a number. An agent gives you context — neighborhood trade-offs, co-op vs. condo rules, and the listings that fit your real budget.

It accounts for income, recurring debts, your down payment, and today's rates — and it understands the rules that make co-ops and condos different.
Most lenders use the 28/36 rule: your housing payment should stay within 28% of gross monthly income, and your total debt — housing plus loans, cards, and other obligations — within 36%. This calculator applies those thresholds to your numbers to estimate a maximum purchase price.
Co-op boards frequently require more post-closing reserves and a lower debt-to-income ratio than a condo or townhouse, so the same income can stretch further in a condo than in a co-op building.
Yes — a larger down payment lowers your loan amount and monthly payment, which raises the price you can carry. Adjust the down payment field to see the effect.
Second homes carry the annual NYC pied-à-terre surcharge, which increases your carrying costs. The calculator factors that charge into the results for second-home scenarios.
Lenders typically apply the 28/36 rule: housing costs stay within 28% of gross monthly income, and total debt stays within 36%. This calculator applies that rule to your income, debts, down payment, and interest rate to estimate a maximum purchase price.
Yes. Co-op boards often require more post-closing liquidity and lower debt-to-income ratios than a condo or townhouse, so the same income can qualify for less in a co-op building.
Use gross (pre-tax) annual income — that is what lenders underwrite against. Enter recurring monthly debt payments, such as loans and minimum card payments, in the debts field.
For a second home it does — the annual surcharge raises your carrying costs and lowers what you can afford. This calculator factors it in once you provide the property's assessed value (for condos and co-ops); the tax is based on that value, not the sale price.
