A housing budget begins with gross monthly income, required monthly debts, and the full PITI payment: principal, interest, property taxes, and homeowners insurance. For $8,000 gross income and $1,200 other required debts, a planning cap of 36% DTI leaves $1,680 per month for PITI; that is a scenario, not a lender approval or a home-price answer.
how much house can i afford: the measured relationship
Housing affordability is the relationship between income, recurring debt obligations, the full monthly home payment, available cash, and a lender's program rules. DTI is the ratio; affordability converts the remaining payment capacity into a property scenario. PITI explains the components of that monthly capacity, while down payment and closing costs address the cash needed before ownership begins.
| Gross monthly income | $8,000 |
|---|---|
| Planning DTI cap | 36% |
| Total debt allowance | $2,880 per month |
| Other debts | $1,200 per month |
| PITI allowance | $1,680 per month |
how much house can i afford: a worked dollar case
Start with $8,000 gross monthly income. At a self-chosen 36% total-debt ceiling, the modeled maximum debt payments are $2,880. Subtract $1,200 of auto, student, and card minimums to leave $1,680 for PITI. If principal and interest on a candidate loan are $1,350, the remaining $330 must cover property tax and homeowners insurance; a $1,350 payment alone is not the housing budget.
how much house can i afford: calculation method
A planning formula is: PITI allowance = gross monthly income × chosen DTI percentage − other required monthly debt payments. Convert a price to a payment only after entering down payment, loan amount, note rate, term, annual property tax, insurance, and any association dues separately.

Common mistakes in How much house can I afford? Use income, debts, and PITI
Do not use annual salary with monthly debts without converting one side. Do not omit property taxes or insurance because they are escrowed; escrow changes how they are paid, not whether they cost money. A low payment can also conceal a short loan term, future rate reset, or small cash reserve.
Where this calculation stops
No universal DTI percentage fits every borrower or loan program. Income stability, debt rules, credit history, property taxes, insurance, mortgage insurance, rate type, cash to close, maintenance, and local rules can all alter a real decision. Test a lower-payment scenario as well as the maximum.
how much house can i afford: source check
The Consumer Financial Protection Bureau identifies PITI as the four basic elements of a monthly mortgage payment and says annual income is generally pre-tax income in a mortgage application. Read the named source. The housingledger record should be reconciled to the disclosure, statement, tax bill, or agreement that governs that exact transaction.
how much house can i afford: using the output
The housingledger output keeps each input's named unit and date adjacent to the result. Update the housingledger scenario when its rate, balance, payment, or property value changes.
