Debt-to-Income Calculator
This debt-to-income calculator divides your monthly debt payments by your gross monthly income to produce the DTI percentage lenders check on every application — and tells you whether yours lands in the good, moderate, or high range.
Free tool · No sign-up · Using it has no impact on your credit score
Income before taxes and deductions, from all sources.
The combined minimum payments across all cards — not your balances.
Debt-to-income ratio
38.3%
Lenders typically want ≤36%; trimming about $140/mo of debt moves you into that range.
Health band
Moderate
Under 36% is Good, 36–43% is Moderate, above 43% is High.
Total monthly debt
$2,300
$2,300 of your $6,000 gross income goes to debt each month.
Where your monthly debt goes
What this calculator tells you
Your debt-to-income ratio is the share of your gross monthly income already committed to debt payments. It's one of the first numbers a lender computes when you apply for a personal loan, car loan, or mortgage, because it predicts whether you can absorb another payment without strain.
This calculator computes the back-end DTI — the version that includes housing plus all other debt — and maps it to the bands lenders actually use: under 36% is comfortable, 36–43% is workable but tighter, and above 43% is where approvals get rare. It also tells you, in dollars, how much monthly debt you'd need to shed to reach the good range.
How it works
Add up every required monthly debt payment — rent or mortgage, car payment, combined credit card minimums, student loans, personal loans, and other obligations like child support — and the calculator divides that total by your gross monthly income. It does not include utilities, groceries, insurance, or subscriptions, because lenders don't count those as debt.
Formula and assumptions
The math is a single division: total required monthly debt payments ÷ gross monthly income × 100. Income is gross — before taxes and deductions — because that's the figure lenders underwrite against.
The band thresholds (36% and 43%) come from standard consumer-lending practice: 36% is the classic back-end ceiling for comfortable approval, and 43% traces to the qualified-mortgage limit that most consumer lenders echo. Individual lenders set their own cutoffs, so treat the bands as strong conventions rather than guarantees.
Example scenario
A household earning $6,000 gross with $1,500 housing, a $400 car payment, $150 in card minimums, and a $250 student loan payment looks like this:
- Debt-to-income ratio
- 38.3%
- Health band
- Moderate
- Total monthly debt
- $2,300
Is my result good or bad?
Under 36% is the green zone: you'll clear the DTI check at nearly every lender and qualify for their better pricing. Between 36% and 43% you're still approvable at many lenders, but expect smaller amounts or higher APRs — the lender is pricing the tightness of your budget. Above 43%, most mainstream lenders decline, and the offers that remain get expensive.
If your number is high, the fastest movers are the ones this calculator quantifies: paying a card down enough to cut its minimum, paying off a small loan entirely, or adding documentable income. Note that DTI is a monthly-payment ratio, not a balance ratio — eliminating one whole payment helps more than shrinking several balances that keep their minimums.
Frequently asked questions
What is a good debt-to-income ratio?
Under 36% is the standard benchmark for a healthy back-end DTI — housing plus all other debt within about a third of gross income. Lenders see room for a new payment and price accordingly. Between 36% and 43% is moderate, and above 43% is high enough that most mainstream lenders decline.
What DTI do lenders want for a personal loan?
Most personal-loan lenders prefer a back-end DTI of 36% or less including the new loan's payment, and many cap approvals somewhere between 40% and 50%. The stronger your credit score, the more DTI flexibility lenders typically extend — but a lower ratio always improves both approval odds and the rate offered.
Does DTI include rent?
Yes — for back-end DTI (the version this calculator computes and most lenders check), your rent or mortgage payment counts as a monthly obligation just like a loan payment. Utilities, groceries, insurance, and subscriptions do not count; only required debt-style payments do.
What's the difference between front-end and back-end DTI?
Front-end DTI counts only housing costs against income and is mostly used in mortgage underwriting (the classic target is 28%). Back-end DTI adds every other debt payment — cars, cards, student loans — and is what personal-loan lenders check. This calculator computes the back-end version.
How do I lower my DTI fast?
Since DTI is a payment ratio, target whole payments: pay off a small loan or a card entirely so its minimum disappears, rather than spreading money across balances whose minimums don't change. On the income side, documentable raises, second income, or consistent freelance earnings all count once you can evidence them.
Does DTI affect my credit score?
No — income isn't in your credit file, so DTI can't appear in your score. But the two travel together: the card balances that push DTI up also raise your credit utilization, which does hurt your score. Lenders look at both, which is why paying down cards improves your application twice over.
