Three calculators. Each one lets you fill in what you know, leave one field unknown, and solve. Then sweep any variable to see how the answer changes.
Maps the connection between your income, debts, down payment, mortgage rate, and local property tax to a feasible home price. Tap SOLVE on any row to make that the unknown.
Front-end DTI = housing payment ÷ gross monthly income. Lenders typically cap this at 28–36%.
The classic amortization formula. Leave any one of price, down payment, APR, term, or monthly P&I empty and solve for it.
Calculates principal & interest only. Taxes and insurance live in the Affordability calculator above.
Selling before the mortgage is paid off. Models remaining principal from the original loan, subtracts agent and closing costs from the sale price, and returns net cash to seller.
Net = current value − remaining mortgage − agent commission − closing costs. Doesn't include capital-gains tax (talk to your CPA).
