Affordable price by down payment

How much house can you actually afford?

Underwriting generally keeps total debt-to-income at or below 36%. Enter income, existing debt payments, cash on hand and the rate, and this works backwards to the monthly housing payment you can carry and the price it supports.

How to use this calculator

  1. Use gross annual income and the required monthly payments on debts that appear in underwriting.
  2. Reserve part of available cash for closing costs and emergencies instead of assigning every dollar to the down payment.
  3. Compare the lender-style DTI result with a personal budget that includes maintenance, childcare and savings goals.

How to read the result

The supported home price is constrained by both the monthly payment ceiling and available cash. If the cash constraint is lower, saving a larger down payment may matter more; if the DTI constraint is lower, price or rate has more influence.

What this estimate does not capture

Qualification is not the same as comfort. Credit score, loan program, reserves, taxes, insurance and lender overlays can change approval, while expenses omitted from DTI can still strain cash flow.

Methodology, assumptions & limits

Inputs are applied directly to standard finance formulas with monthly compounding where relevant. Results are estimates in the selected currency; they do not include every tax, fee, benefit, market event or local rule. Try a conservative and an optimistic case before making a decision.

Frequently asked questions

How many times my income can I borrow?

At 6–7% rates, three to four times annual income is typical. The DTI limit and the rate move it a lot.

What does a 36% DTI mean?

Housing plus other debt payments should stay under 36% of gross monthly income. A conservative target is 28% for housing alone.

How much down payment do I need?

20% avoids PMI, while FHA loans start at 3.5%. The table compares the price each level supports.

What counts as other debt?

Add up recurring debt payments — car loans, student loans, credit card minimums.
