Calculation notes
Understand the Home affordability calculator
Housing budget = min(gross monthly income × housing ratio, gross monthly income × total DTI limit − existing debt). Solve the home price whose mortgage, tax, insurance, HOA and PMI fit that budget. The calculation runs locally and keeps cash-flow timing consistent with the stated assumptions.
Formula and logic
How much house can I afford based on income and monthly debt?
Housing budget = min(gross monthly income × housing ratio, gross monthly income × total DTI limit − existing debt). Solve the home price whose mortgage, tax, insurance, HOA and PMI fit that budget.
Worked example
What housing budget does a $100,000 income allow at 28% DTI?
At $100,000 annual income, $500 monthly debt, and 28% / 36% limits, the housing budget is the lesser of $2,333.33 and $2,500, before translating it into a home price.
How to read the result
Are 28% housing and 36% total debt ratios lender requirements?
The default 28% and 36% ratios are planning assumptions, not universal lender rules.
A larger down payment can reduce both financed principal and PMI.
Limits and assumptions
Does a home affordability estimate count as mortgage preapproval?
This is not preapproval. Credit score, reserves, lending program, local taxes, income stability, closing costs and actual underwriting can change the result.
