How this calculator works.
Lenders cap your total monthly debts, including the new housing payment, at a share of your gross monthly income. That share is the back-end debt-to-income ratio. The calculator takes the limit you choose, subtracts your current debts, and treats what is left as the most the full housing payment can be.
The full payment includes principal and interest, property tax, homeowners insurance, HOA dues and, when you put less than 20% down, private mortgage insurance. Because tax and mortgage insurance grow with the price, the calculator solves for the price directly rather than guessing.
The front-end ratio is the housing payment alone divided by income. It is shown for reference; many programs focus on the back-end ratio, but a conservative budget often keeps housing near 28% of income. The table below shows the maximum price at each common limit.
Max housing payment = gross monthly income × DTI limit − monthly debts. Max price solves P&I(price − down) + tax + insurance + HOA + PMI = max housing payment.
