Is DTI based on gross or net income?

It is commonly calculated with gross monthly income before taxes, although lender methods and accepted income can vary.

What payments belong in DTI?

Include recurring required debts such as housing, card minimums, installment loans, and other obligations a lender requests.

Is 43% the maximum DTI for every personal loan?

No. It is a common planning reference, not a universal personal-loan approval rule. Each lender sets its own standards.

Do I use the credit card balance or minimum payment for DTI?

Use the required monthly payment, not the full balance. A lender may calculate the obligation differently when no payment is reported.

Can a lender calculate a different DTI than this tool?

Yes. The lender may verify different income, include additional obligations, or apply product-specific calculation rules.

How can I reduce my proposed DTI before applying?

Request less, pay down obligations, avoid adding debt, or wait for documented income changes. Do not omit debts or overstate income.

Can I still check rates if my DTI estimate is high?

You can explore available partner responses, but approval and terms vary. Consider a smaller amount and make sure any resulting payment is sustainable.

Direct answer

How do you calculate debt-to-income ratio?

Debt-to-income ratio is total required monthly debt payments divided by gross monthly income, expressed as a percentage. This calculator shows the current ratio, the ratio after adding a proposed loan payment, and illustrative payment room at two planning thresholds. Different lenders and loan products use different limits and may classify income or debts differently.

This calculator uses gross income. A lender may classify obligations differently and apply its own DTI standard.

Best fit

This calculator is most useful when

+Borrowers who want to test a specific cost or affordability question before checking a live rate
+Anyone comparing scenarios with consistent assumptions instead of relying on payment alone

Consider instead

You may need a different comparison if

!Use the main personal-loan calculator when you only need a standard payment and interest estimate
!Use the comparison hub when the decision is between different credit products rather than two numeric scenarios

How to calculate DTI

Add recurring monthly debt payments, divide by gross monthly income, and multiply by 100. The proposed ratio adds the possible new loan payment before dividing.

Housing, credit-card minimums, auto loans, student loans, support obligations, and other required payments may be included. Normal living expenses are generally not part of the ratio.

How lenders use DTI

DTI helps lenders judge whether another payment fits beside existing obligations, but it is not the only underwriting factor. Credit history, income stability, requested amount, and bank verification can also matter.

A ratio below a planning threshold does not guarantee approval, and a higher ratio does not create one universal decline rule across every lender.

Which monthly payments should be entered in DTI?

Include recurring required obligations such as housing, auto loans, student loans, installment loans, credit-card minimums, and support obligations when applicable. Use the payment due each month rather than the full balance.

Ordinary living expenses are not usually part of the ratio, but they still affect affordability. A complete budget test should sit beside the DTI calculation rather than being replaced by it.

Current DTI versus proposed DTI

Current DTI measures obligations before the new loan. Proposed DTI adds the estimated new payment. The second figure is the more relevant planning check when deciding whether another installment payment fits.

If a personal loan will pay off debts, lender treatment can differ from simply adding the new payment. For conservative planning, compare both the temporary overlap and the expected post-payoff obligations.

Why there is no universal personal loan DTI cutoff

DTI is one measure of repayment capacity, not a universal approval rule. Lenders can weigh credit history, income stability, requested amount, recent delinquencies, bank information, and other risk factors alongside the ratio.

Use 36% and 43% only as planning references in this tool. They are not guarantees, legal limits for every product, or representations of every partner’s underwriting policy.
