44.17% — high, $490 a month from good. $2,650 of monthly debt on $6,000 of gross monthly income puts the ratio at 44.17%, above the 43% lender line. Cutting $490 a month gets it to 36%; earning $7,361.11 a month does the same. Enter your debts and income to see your ratio and what moves it.
Debt-to-income ratio is the total monthly debt divided by gross monthly income, times 100 — the number a lender checks first. This calculator works it out, names the band it sits in, and says exactly how much debt to cut, or how much income you need, to reach the band you want — so the number you get is the number on the application.
Debt-to-income ratio is the total monthly debt divided by gross monthly income, times 100. Add every monthly debt payment — housing, car, student loan, credit card minimums and anything else — then divide by the gross pay before tax, and multiply by 100. The front-end ratio is the housing payment alone, divided by the same income, times 100. The bands are 36% or under good, 37 to 43% acceptable, 44 to 49% high, and 50% or more very high. Lenders commonly cap back-end DTI at 43% for a qualified mortgage.
At the defaults — gross monthly income $6,000, housing $1,800, car $350, student loan $250, credit card minimums $150, other debts $100 — the total debt is $1,800 + $350 + $250 + $150 + $100 = $2,650, and the ratio is $2,650 ÷ $6,000 × 100 = 44.17% (high). The front-end ratio is $1,800 ÷ $6,000 × 100 = 30.00%. Housing is 67.92% of the debt, so the housing payment is the lever that moves the ratio most.

| Housing $1,500 | $2,350.00 | 39.17% (acceptable) | 25.00% |
| No car payment | $2,300.00 | 38.33% (acceptable) | 30.00% |
| No credit cards | $2,500.00 | 41.67% (acceptable) | 30.00% |
| Housing $1,200 | $2,050.00 | 34.17% (good) | 20.00% |
| Pay off car + cards | $2,150.00 | 35.83% (good) | 30.00% |
| Income $6,500 | $2,650.00 | 40.77% (acceptable) | 27.69% |
| No student loan | $2,400.00 | 40.00% (acceptable) | 30.00% |
| Housing $2,000 | $2,850.00 | 47.50% (high) | 33.33% |
| Income $7,361.12 | $2,650.00 | 36.00% (good) | 24.45% |
| Debt $3,000 | $3,000.00 | 50.00% (very high) | 30.00% |
| Flip: income $4,500 | $2,650.00 | 58.89% (very high) | 40.00% |
| Flip: housing $2,500 | $3,350.00 | 55.83% (very high) | 41.67% |
Setup: gross monthly income $6,000, housing $1,800, car $350, student loan $250, credit card minimums $150, other debts $100.
Line 1 — the total debt. $1,800 + $350 + $250 + $150 + $100 = $2,650 a month.
Line 2 — the ratio. $2,650 ÷ $6,000 × 100 = 44.17%, which is the high band (44 to 49%).
Line 3 — the front-end ratio. $1,800 ÷ $6,000 × 100 = 30.00%.
Line 4 — the distance to 36%. The most debt allowed at 36% is 36% × $6,000 = $2,160, so the cut needed is $2,650 − $2,160 = $490 a month.
Line 5 — the distance to 43%. The most debt allowed at 43% is 43% × $6,000 = $2,580, so the cut needed is $2,650 − $2,580 = $70 a month.
Reverse: to reach 36% on this debt you need $2,650 ÷ 0.36 = $7,361.11 a month of income; for 43% you need $2,650 ÷ 0.43 = $6,162.79 a month; for 50% you need $5,300.00 a month. There is $350 of headroom before 50%: 50% × $6,000 = $3,000, and $3,000 − $2,650 = $350.
Income $5,000: the debt is still $2,650, so the ratio is $2,650 ÷ $5,000 × 100 = 53.00% (very high), and the front-end ratio is $1,800 ÷ $5,000 × 100 = 36.00%. A smaller income lifts both ratios, because the same debt is divided by less.
Income $7,000: the ratio is $2,650 ÷ $7,000 × 100 = 37.86% (acceptable), and the front-end ratio is 25.71%. A $1,000 raise moves the ratio from high to acceptable.
Housing $1,500: the debt falls to $2,350, so the ratio is $2,350 ÷ $6,000 × 100 = 39.17% (acceptable), and the front-end ratio is 25.00%. Cheaper housing is the biggest single cut, because housing is 67.92% of the debt.
No car payment: the debt falls to $2,300, so the ratio is $2,300 ÷ $6,000 × 100 = 38.33% (acceptable). Clearing the $350 car payment moves the ratio from high to acceptable on its own.
No credit cards: the debt falls to $2,500, so the ratio is $2,500 ÷ $6,000 × 100 = 41.67% (acceptable). The $150 of minimums is the smallest debt, so clearing it moves the ratio least.
Housing $1,200: the debt falls to $2,050, so the ratio is $2,050 ÷ $6,000 × 100 = 34.17% (good), and the front-end ratio is 20.00%. A $600 cheaper home takes the ratio from high to good in one move.
Pay off car + cards: the debt falls to $2,150, so the ratio is $2,150 ÷ $6,000 × 100 = 35.83% (good). Clearing the $350 car and the $150 cards together cuts $500, which is more than the $490 needed for 36%.
Income $6,500: the ratio is $2,650 ÷ $6,500 × 100 = 40.77% (acceptable), and the front-end ratio is 27.69%. A $500 raise moves the ratio from high to acceptable.
No student loan: the debt falls to $2,400, so the ratio is $2,400 ÷ $6,000 × 100 = 40.00% (acceptable). Clearing the $250 student loan moves the ratio from high to acceptable.
Housing $2,000: the debt rises to $2,850, so the ratio is $2,850 ÷ $6,000 × 100 = 47.50% (high), and the front-end ratio is 33.33%. A $200 dearer home lifts the ratio by 3.33 points.
Income $7,361.12: the ratio is $2,650 ÷ $7,361.12 × 100 = 36.00% (good), at the very edge of the good band, and the front-end ratio is 24.45%. The exact income for 36% is $7,361.11, but at that cent the unrounded ratio is a hair over 36%, so $7,361.12 is the first cent that lands in the good band.
Debt $3,000: the ratio is $3,000 ÷ $6,000 × 100 = 50.00% (very high), at the very edge of the very high band. One more $350 debt takes the defaults to exactly 50%.
Flip — income $4,500: the ratio is $2,650 ÷ $4,500 × 100 = 58.89% (very high), and the front-end ratio is 40.00%. The same debt on a much smaller income is deep in the very high band.
Flip — housing $2,500: the debt rises to $3,350, so the ratio is $3,350 ÷ $6,000 × 100 = 55.83% (very high), and the front-end ratio is 41.67%. A $700 dearer home flips the answer from high to very high.
Reverse — the cut and the income for each line: the most debt allowed at 36% is $2,160, so cut $490 a month; at 43% the most allowed is $2,580, so cut $70 a month. There is $350 of headroom before 50%. To reach 36% on this debt you need $7,361.11 a month of income; for 43% you need $6,162.79 a month; for 50% you need $5,300.00 a month.
Edges: no debt at all is 0.00% (good); debt equal to income is 100.00% (very high); debt over income is over 100%, and the result flags it as over your income.
The model assumes the gross monthly income and the six monthly debt payments you enter, and it counts the minimum payments on credit cards, not the full balances. It assumes the income and the debts stay fixed while you work the numbers, and it leaves out taxes, the credit score, the down payment, cash reserves and the rest of a lender's underwriting — the 43% line is the usual cap for a qualified mortgage, and some lenders allow up to 45 to 50% with compensating factors, as general guidance, not a guarantee. Rounding convention: percentages are shown to two decimals, money is rounded to cents, and all figures are computed from unrounded values, rounded only for display.

The math is exact for the numbers you enter: the total debt is the six monthly payments added together, the ratio is the total debt divided by gross monthly income times 100, and the band follows the percentage. What the model cannot do is read your pay stubs or your statements for you: check the gross income and the minimum payments on the statements, because a $4,500 income and a $7,000 income give very different answers. It counts the minimum payments on credit cards, not the full balances, and it leaves out taxes, the credit score, the down payment, cash reserves and the rest of a lender's underwriting. For the card ratio behind the minimums, see credit utilization calculator; for lowering the ratio step by step, see how to lower your debt-to-income ratio.
Bright Side Kit. "Debt-to-Income Ratio Calculator: DTI & Limits 2026." https://brightoolbox.com/debt-to-income-ratio-calculator/ Accessed October 25, 2026.36% or under is good. The bands are 36% or under good, 37 to 43% acceptable, 44 to 49% high, and 50% or more very high. At the defaults the ratio is 44.17%, which is high — $490 a month of cuts takes it to 36.00%.
Add the monthly debts, divide by gross monthly income, times 100. At the defaults that is ($1,800 + $350 + $250 + $150 + $100) ÷ $6,000 × 100 = $2,650 ÷ $6,000 × 100 = 44.17%. The front-end ratio is the housing payment alone: $1,800 ÷ $6,000 × 100 = 30.00%.
43% is the usual line. Lenders commonly cap back-end DTI at 43% for a qualified mortgage, and some allow up to 45 to 50% with compensating factors such as a big down payment or cash reserves. At the defaults the ratio is 44.17%, which is $70 a month over the 43% line.
$490 a month. The most debt allowed at 36% on a $6,000 income is 36% × $6,000 = $2,160, and the debt now is $2,650, so $2,650 − $2,160 = $490. Paying off the car and the cards together cuts $500, which takes the ratio to 35.83%.
$7,361.11 a month. The debt of $2,650 divided by 0.36 is $7,361.11, and at that income the ratio is 36.00%. For 43% the income needed is $6,162.79 a month, and for 50% it is $5,300.00 a month.
Yes — it takes the ratio to 38.33%. Dropping the $350 car payment takes the debt from $2,650 to $2,300, and $2,300 ÷ $6,000 × 100 = 38.33%, which is the acceptable band. Paying off the car and the cards together takes it to 35.83%, which is good.
It is very high, and lenders will push back. At 50.00% the debt is $3,000 on a $6,000 income, and at 58.89% the income is only $4,500 against the same $2,650 of debt. There is $350 of headroom before 50% at the defaults — one more $350 debt crosses it.
