DTI Calculator
What Is Debt-to-Income Ratio?
Your debt-to-income ratio, or DTI, is a personal finance measurement that compares your required monthly debt payments with your gross monthly income. Lenders commonly use DTI to determine whether you can reasonably manage your existing debts and take on another monthly payment.
DTI does not compare your total outstanding debt balances with your income. Instead, it looks at the monthly payments you are required to make.
Monthly debt payments used in a DTI calculation may include:
- Mortgage or rent-related debt payments used by the lender
- Student loan or Parent PLUS loan payments
- Credit card debt minimum payments
- Auto loan or lease payments
- Personal loan payments
- Required payments on other recurring debts
- Alimony or child support obligations when applicable
Expenses such as groceries, utilities, insurance premiums, entertainment, and other everyday living expenses generally are not part of the standard DTI formula, even though they still matter when determining what you can actually afford.
How to Calculate Your Debt-to-Income Ratio
Formula:
Total Monthly Debt Payments ÷ Gross Monthly Income × 100 = Debt-to-Income Ratio
Your gross monthly income is the income you earn before taxes and other payroll deductions.
Debt-to-Income Ratio Example
- Mortgage payment: $1,800 per month
- Car payment: $450 per month
- Student loan payment: $250 per month
- Credit card minimum payments: $200 per month
- Total monthly debt payments: $2,700
- Gross monthly income: $7,500
$2,700 ÷ $7,500 × 100 = 36%
In this example, 36% of the person’s gross monthly income is committed to monthly debt payments.
Why Is Your DTI Important?
- Loan approval: Lenders use DTI as one way to determine whether you have enough income to repay your debts and handle another loan payment.
- Borrowing capacity: A high DTI can limit how much additional debt a lender is willing to approve because more of your income is already committed to existing payments.
- Financial flexibility: Even when you qualify for financing, a high DTI can leave less monthly income available for savings, emergencies, retirement, insurance, and everyday expenses.
- Interest and loan options: DTI is one of several factors lenders may consider when determining what financing you qualify for. Your credit history, credit score, income, assets, down payment, and type of loan may also matter.
What Is a Good Debt-to-Income Ratio?
There is no single DTI percentage that applies to every lender or every type of loan. In general, a lower DTI gives you more financial breathing room because less of your gross income is committed to debt. Mortgage lenders, auto lenders, and other creditors may use different DTI limits and underwriting standards.
| DTI Range | What It May Indicate | What to Consider |
|---|---|---|
| Under 36% | Lower portion of income committed to debt | Generally provides more room for savings, expenses, and additional payments |
| 36%–43% | Moderate debt load | Loan qualification may depend more heavily on the lender, loan type, credit, income, and other factors |
| Above 43% | Larger portion of income committed to debt | Additional borrowing may become more difficult and monthly cash flow may become tighter |
These ranges are general planning benchmarks, not universal lending rules. A lender may approve a borrower with a higher DTI or impose a lower limit depending on the loan program and the borrower’s overall financial situation.
How to Lower Your Debt-to-Income Ratio
There are only two basic ways to lower your DTI: reduce your required monthly debt payments or increase your gross monthly income. Life insurance and annuities can protect your household financially, but buying them does not directly lower your DTI.
- Pay down revolving debt: Reducing credit card balances can eventually lower required minimum monthly payments and reduce the amount of debt you carry.
- Pay off smaller loans: Eliminating an auto loan, personal loan, or other monthly obligation removes that payment from your DTI calculation.
- Avoid unnecessary new debt: A new car payment, personal loan, or financed purchase can immediately increase your monthly obligations.
- Increase income: Higher documented gross income can reduce your DTI if your monthly debt payments remain the same.
- Review refinancing carefully: Refinancing may reduce a monthly payment in some situations, although extending the repayment period can increase the total interest paid over time. Use our interest rate calculator when comparing borrowing costs.
Why Parents and Families Should Look Beyond DTI
Your DTI tells you how much of your current income is committed to monthly debt. It does not tell you what would happen to those debts if you died or could no longer earn an income.
This distinction is especially important for parents, homeowners, married couples, and anyone whose family depends on their paycheck. A household may have a reasonable DTI today but still face a major financial problem if one income suddenly disappears.
- A surviving spouse may have to make the mortgage payment with one income instead of two.
- Car loans, credit cards, and other household debts may still need to be paid.
- Children’s education plans may have to be reduced or postponed.
- Savings or the estate may have to be used to cover debts instead of being left as an inheritance.
- Cosigned debts may create additional problems for surviving borrowers or cosigners.
Calculate Your Life Insurance Coverage Gap Separately
Do not use your debt-to-income ratio to determine how much life insurance your family needs. DTI measures monthly affordability. Life insurance planning looks at the financial obligations and income your family may need to replace if you die.
A simple starting point is:
Total Financial Obligations − Available Life Insurance and Other Resources = Coverage Gap
Life Insurance Coverage Gap Example
- Mortgage balance: $350,000
- Car loans and credit cards: $30,000
- Final expenses: $20,000
- Cosigned student loans or other obligations: $25,000
- Total financial obligations: $425,000
- Available life insurance: $300,000
- Potential coverage gap: $125,000
This $125,000 difference is a life insurance coverage gap, not a debt-to-income ratio. The actual amount of life insurance a family needs may also depend on lost future income, savings, retirement accounts, education expenses, survivor income, Social Security benefits, and other assets or obligations.
Life Insurance That Can Protect a Family With Debt
Life insurance does not directly reduce your DTI. Its job is different: it provides money to your beneficiaries if you die. That money can help replace lost income, pay debts, keep the mortgage current, fund education, and give your family time to adjust financially.
Term Life Insurance
- How it works: Provides a fixed death benefit for a specified period, such as 10, 20, 30, or in some cases 40 years.
- Pros: Typically provides a large amount of life insurance for a relatively low premium.
- Cons: Coverage expires at the end of the term unless it is renewed, converted, or replaced.
- Who may need it: Parents with young children, homeowners with mortgages, families depending on employment income, and people with significant debts.
- Who may not need it: People with no financial dependents and enough assets to cover their debts and final expenses.
Return of Premium Term Life Insurance
- How it works: Provides term life insurance and may return eligible premiums if you keep the policy for the entire specified term and meet the policy requirements.
- Pros: Provides temporary life insurance protection with the potential return of eligible premiums at the end of the term.
- Cons: Usually costs more than comparable traditional term life insurance.
- Who may need it: Buyers willing to pay more for term insurance because they value the return-of-premium feature.
- Who may not need it: Budget-conscious families whose priority is obtaining the largest affordable death benefit.
Whole or Universal Life Insurance
- How it works: Permanent life insurance is designed to provide lifelong coverage when the policy requirements are met. Some policies also build cash value.
- Pros: Can provide lifelong death-benefit protection and may be useful for legacy, estate, or lifelong dependent planning.
- Cons: Premiums are generally higher than term life insurance for the same initial death benefit.
- Who may need it: Families with lifelong dependents, business owners, and people with long-term estate or estate tax planning needs.
- Who may not need it: Families whose main goal is obtaining the most death benefit possible for the lowest premium during their working years.
Employer coverage can help, but group life insurance may not provide enough coverage for every household and may be tied to your employment. Individual term or permanent life insurance can provide additional protection based on your family’s needs.
Annuities Can Help Protect Retirement Income
An annuity does not directly lower your debt-to-income ratio either. However, an annuity can help create guaranteed retirement income, which may be valuable when a household wants predictable income for one or both spouses later in life.
Fixed Indexed Annuities With GLWB Riders
- How it works: A fixed indexed annuity with a guaranteed lifetime withdrawal benefit can generate income that continues for life, subject to the contract terms.
- Pros: Can help provide a surviving spouse with income for life. Depending on the contract, joint lifetime income may continue as long as either covered spouse is alive.
- Cons: Annuities have surrender periods and are generally better suited for retirement income planning than short-term liquidity.
- Who may need it: Married couples near or in retirement who want to protect their household income stream.
- Who may not need it: Younger families whose immediate priority is inexpensive life insurance and paying down debt.
Retirement accounts such as an IRA, Roth IRA, or certain employer plans may be used to fund an annuity when appropriate. After-tax savings may also be used. You can use our annuity calculator to compare potential retirement income.
Single Premium Immediate Annuities
- How it works: A single premium immediate annuity converts a lump sum into a stream of scheduled income payments.
- Pros: Can create predictable retirement income immediately and may offer lifetime payment options.
- Cons: Traditional SPIAs generally provide less access to the original lump sum after income begins. Contract options can also affect the amount left to beneficiaries.
- Who may need it: Retirees who prioritize immediate, predictable income over liquidity.
- Who may not need it: People who need substantial access to their principal or prefer greater control over their retirement assets.
Other Insurance That Can Protect Your Finances
- Mortgage Protection Insurance: Provides coverage designed to help protect the mortgage if you die.
- Final Expense Life Insurance: Provides a death benefit that can be used for funeral costs and other final expenses.
- Long-Term Care Annuities or Long-Term Care Insurance: Can help pay qualifying long-term care expenses instead of relying entirely on household savings.
- Disability Insurance: Can replace part of your income if a qualifying illness or injury prevents you from working. This can be especially important when your household has significant monthly debt payments.
Who Should Pay Close Attention to Their DTI?
- People planning to apply for a mortgage or refinance
- Homeowners carrying significant monthly debt
- People with large credit card balances
- Borrowers with student loans, auto loans, or personal loans
- Families living primarily on one income
- Anyone considering taking on another major monthly payment
- Parents trying to balance debt repayment with retirement and college savings
Who May Be Less Concerned About DTI?
DTI may be less important for someone who is not planning to borrow money and has little or no debt. However, monthly cash flow still matters even when a lender is not involved.
- Retirees with little or no debt and sufficient retirement income
- People who own their home outright and have few recurring debt payments
- Families with substantial liquid assets and very little outstanding debt
DTI vs. Life Insurance Coverage: Know the Difference
| Calculation | What It Measures | Formula |
|---|---|---|
| Debt-to-Income Ratio | How much of your gross monthly income goes toward required monthly debt payments | Monthly Debt Payments ÷ Gross Monthly Income × 100 |
| Life Insurance Coverage Gap | Potential difference between financial obligations and resources available to survivors | Financial Obligations − Available Coverage and Resources |
These calculations answer completely different questions. Your DTI helps measure your current debt burden relative to income. A life insurance coverage-gap calculation helps determine whether your family may have enough financial resources if you die.
The Bottom Line
Your debt-to-income ratio is straightforward: add your required monthly debt payments, divide them by your gross monthly income, and multiply by 100. The lower the percentage, the less of your income is committed to debt and the more financial flexibility you generally have.
But DTI is only part of the picture. Parents, homeowners, and married couples should also consider what happens to those monthly obligations if one person’s income disappears because of death or disability.
Paying down debt can improve your DTI. Life insurance, disability insurance, and guaranteed retirement income can address a different problem by helping protect the household income used to pay those bills.

Questions From Our Readers
What is a good debt-to-income ratio?
There is no single DTI limit that applies to every lender. Lower is generally better because less of your gross monthly income is committed to debt, but acceptable limits depend on the lender, loan type, credit profile, income, and other underwriting factors.
Can my debt-to-income ratio affect my credit score?
Your DTI and credit score are separate measurements. Lenders may consider both when evaluating an application, but DTI compares your monthly debt payments with your gross monthly income.
How often should I calculate my debt-to-income ratio?
Calculate your DTI whenever your income or monthly debt payments change significantly, especially before applying for a mortgage, auto loan, refinance, or other major financing.
Can I calculate my debt-to-income ratio without a calculator?
Yes. Add your required monthly debt payments, divide the total by your gross monthly income, and multiply by 100. For example, $2,000 of monthly debt divided by $6,000 of gross income equals a 33.3% DTI.
What is an income-to-debt ratio calculator?
It generally refers to a debt-to-income calculator. The calculator compares required monthly debt payments with gross monthly income to show what percentage of your income is already committed to debt.
