DTI Calculator
Check Your Ratio, Find Your Lender Match
DTI thresholds are guidelines, not guarantees. Lenders consider credit score, income stability, and other factors alongside DTI.
Key Takeaways
- A borrower earning $5,000/month with $1,900 in monthly debt payments has a 38% DTI — qualifying at most major personal loan lenders but missing the best rates.
- Lenders generally consider DTI below 36% as “good,” 36%–43% as “acceptable,” and above 43% as “high risk.” Most personal loan lenders cap DTI at 40%–50%.
- The calculator includes a “Proposed New Loan” field that shows how adding a new monthly payment changes your DTI — helping you size the right loan before you apply.
- The lender qualification panel shows eight major lenders with their max DTI thresholds and whether you qualify, are borderline, or exceed their limit at your current ratio.
- Only minimum monthly payments count toward DTI — not total balances. A $20,000 credit card balance with a $400 minimum adds $400 to your debt total, not $20,000.
How to Use This Calculator
This calculator computes your debt-to-income ratio and shows which personal loan lenders are likely to approve your application at that level. It breaks debt into three categories (housing, loans, credit cards) for accuracy.
Step 1 — Enter your gross monthly income. This is your income before taxes and deductions. Include all regular income sources: salary, freelance, rental income, alimony, Social Security, etc. If you have a co-borrower, combine both incomes.
Step 2 — Fill in your monthly debt payments. Enter the minimum required payment for each category — not the total balance, and not what you choose to pay above the minimum. For credit cards, enter the sum of all minimum payments across all cards. For rent or mortgage, include property taxes and insurance if they are part of your monthly payment.
Step 3 — Add a proposed loan payment (optional). If you are considering a new personal loan, enter the estimated monthly payment. The calculator will show your DTI both with and without the new loan, plus update the lender qualification panel to reflect the higher DTI. Use the Personal Loan Calculator to estimate the monthly payment for a specific loan amount and rate.
Step 4 — Review your DTI category and lender matches. The gauge shows where you fall on the 0%–65% spectrum. The color-coded category box explains what your DTI means for loan approval. The lender panel shows eight personal loan lenders with their max DTI limits and your qualification status.
Understanding the Results
Your debt-to-income ratio is calculated by dividing your total monthly debt payments by your gross monthly income, then multiplying by 100. A borrower paying $1,900/month in debts on $5,000/month income has a DTI of 38%. This single number is one of the most important factors lenders evaluate when deciding whether to approve your loan application and at what rate.
The gauge visualization maps your DTI onto a semicircle with four color zones. Green (0%–35%) represents the range where most lenders offer their best terms. Yellow (36%–43%) is the zone where you still qualify at many lenders but may pay a slightly higher rate. Orange (44%–50%) is high — only lenders with generous DTI limits will approve. Red (above 50%) means most personal loan lenders will decline.
The lender qualification panel is the most actionable output. Each lender card shows three things: the lender’s maximum DTI threshold, a brief note about the lender, and your qualification status. “Likely qualifies” (green) means your DTI is at least 5 points below the lender’s cap. “Borderline” (yellow) means you are within 5 points of the limit — approval is possible but depends on credit score and income. “Over max DTI” (red) means your ratio exceeds that lender’s stated maximum.

Frequently Asked Questions
What is a good debt-to-income ratio for a personal loan?
Most personal loan lenders prefer a DTI below 36%, which qualifies you for the most competitive rates and highest approval odds. DTI of 36%–43% is still acceptable at most lenders. Above 43%, options narrow significantly, and above 50%, only a few lenders will consider your application. The calculator shows exactly which lenders approve at your DTI level.
What counts as “debt” in the DTI calculation?
Monthly minimum required payments on: rent or mortgage (including property tax and insurance), auto loans, student loans, personal loans, credit card minimums, child support, alimony, and any other recurring debt obligations. Utilities, insurance premiums, groceries, and subscriptions do not count toward DTI.
Does my DTI affect the interest rate I receive?
Yes. Borrowers with lower DTI ratios typically receive lower interest rates because they represent less risk to lenders. The exact impact varies by lender, but a 5-point DTI improvement (e.g., from 40% to 35%) can translate to a 1%–3% APR reduction, saving hundreds or thousands over the loan term.
How can I lower my DTI before applying?
Three strategies: (1) Pay off the debt with the smallest monthly payment to eliminate it entirely. (2) Increase your income through a raise, side work, or adding a co-borrower. (3) Refinance existing loans to lower monthly payments — though this may extend the term. The most effective approach is usually eliminating a small recurring payment, such as paying off a small credit card balance entirely.
Does rent count toward DTI?
Yes. Your rent payment is included in the DTI calculation for personal loans. Unlike mortgages, where only the proposed housing payment is used for “front-end DTI,” personal loan lenders use your total DTI including current rent. If you are applying for a mortgage, lenders calculate DTI using the proposed mortgage payment instead of rent.
Is the DTI threshold the same for all loan types?
No. Personal loan lenders typically cap DTI at 40%–50%. Conventional mortgages use a 43% maximum (with some exceptions up to 50%). FHA mortgages allow up to 57% in some cases. Auto lenders vary widely. This calculator focuses on personal loan lender thresholds specifically.
