How the Required Income Calculator works

Calculate the income needed to qualify for your target home price.

Show the math

Formula

Required monthly income = target PITI ÷ front-end DTI limit. Multiply by 12 for annual income and account for existing debts against the back-end limit.

Inputs

Target home price (USD)
Down payment (USD)
Loan term (years)
Interest rate (%)
Monthly debts (USD)

Notes

This calculator cannot see overtime history, 1099 expenses, or a down year. Enter a documented average.
A typed rate is not a quote, a lock, or APR.

Rates, terms, and payments are illustrative estimates, not a quote or a commitment to lend. Not a substitute for underwriting. Equal Housing Lender. See our licensing and disclosures page.

Variable income and this income calculator

The calculator works backward from a price to an illustrative income need. It cannot see overtime history, 1099 expenses, or a down year. Snapshot as of 2026-08.

Target price and down payment: Together they set the loan amount. Closing costs and prepaids are not this loan amount.
Rate and term: Illustration only. A typed rate is not a quote. Term changes payment more than most people expect.
Monthly debts: Back-end DTI uses counted debts. Back-end DTI is all counted monthly debts divided by gross monthly income. Variable income is still averaged before this ratio is run.

Terms used in this calculator

DTI (Debt-to-Income Ratio): The share of your gross monthly income taken up by monthly debt payments, including the proposed housing payment.
Pre-qualification: An early estimate of what you might borrow, based on information you provide rather than verified documentation.
