Enter gross monthly income and at least one obligation you want included. AutoUnite does not source personal income or debt and never turns a missing obligation into $0.

UNDERSTAND THE ESTIMATE

How the Debt-to-Income Calculator works

Estimate debt-to-income ratios from the financial facts you choose to enter. AutoUnite keeps housing, recurring debts, and a proposed car payment distinct so missing obligations stay clearly marked and housing is not counted twice.

What you need to get started

This calculator uses the following inputs to build an estimate. Check your own agreement or quote when a rate, fee, or contract value is required.

  • Gross Monthly Income

You can also refine your scenario with information such as Monthly Debts (excluding housing / proposed car), Housing Payment, Proposed Car Payment, Housing included in monthly debts?. Enter details only when known; an unknown fee, rate, or benefit is not automatically zero.

How the estimate is built

  1. Enter gross monthly income before taxes and deductions.
  2. Add only the recurring debts, housing payment, and proposed car payment you want included.
  3. Identify whether housing is already included in the monthly-debt amount when that fact is known.
  4. Review each available DTI ratio as a scenario estimate, not lender approval or a qualification decision.

Example

A shopper can enter $8,000 of gross monthly income, $1,200 of recurring debts, a $1,800 housing payment, and a $500 proposed car payment. AutoUnite can show the housing-only ratio, debts-plus-proposed-car ratio, and the full obligations ratio without publishing the income itself as a result.

Common debt-to-income questions

Does this DTI calculator tell me whether I qualify for a car loan?

No. It estimates ratios from the values you provide. Lenders can use different underwriting rules, data, and thresholds.

What happens if I do not know one of my debts?

It stays missing and is not converted to zero. The result includes only obligations that are actually provided.

Why does AutoUnite ask whether housing is already in monthly debts?

That confirmation helps prevent the same housing payment from being counted twice when both fields are present.

Does AutoUnite look up my income or debts?

No. Personal income, debt, housing, and proposed-payment values are entered by you for this calculation.

Is a lower DTI an approval promise?

No. The ratio is descriptive budgeting information and is not an approval, lender offer, or eligibility determination.
