How to use it
- Annual Income — in home buying budget, this value feeds the formula directly, and the steps panel shows exactly where it enters the max price.
- Down Payment — in home buying budget, this value feeds the formula directly, and the steps panel shows exactly where it enters the max price.
- Monthly Debts — used in the first stage of the calculation, so entering it accurately matters more than any later refinement.
- The output panel in home buying budget leads with the headline result and follows with the steps behind it, so the value can be checked rather than assumed.
- Iterate. Vary the inputs one at a time; the movement in the result shows which lever matters most for your home buying budget question.
The formula behind the result

Where it helps
