Frequently asked questions
Plain-language answers about when to use the estimate, what your numbers mean, what is left out, and how privacy works.
When should I use the Debt-to-Income Ratio Calculator?
Use it when you want to test the exact inputs on this page: Estimate DTI before a loan or mortgage conversation. See how a proposed housing payment changes the ratio. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
What do the main Debt-to-Income Ratio Calculator inputs mean?
Gross monthly income means monthly income before taxes and deductions. DTI is usually discussed from gross income, not take-home pay. Monthly debt payments means recurring debt payments such as credit card minimums, auto loans, student loans, personal loans, and other listed debts. Proposed housing payment means the housing payment you want to test. Include taxes, insurance, HOA, or mortgage insurance here only if you want them counted in the ratio.
What counts as monthly debt payments?
Use recurring debt payments such as credit card minimums, auto loans, student loans, personal loans, child support if applicable, and other debts you want counted. Normal living costs like groceries and utilities are important for your budget, but they are not always counted the same way in a lender DTI check.
Should I use gross income or take-home pay?
Use gross monthly income for this DTI estimate because lenders commonly discuss debt-to-income ratio from income before taxes and deductions. Use take-home pay for your personal budget check, because that shows what you actually have available each month.
Should the housing payment include taxes, insurance, and HOA?
If you are testing a mortgage-style housing payment, include property tax, homeowners insurance, HOA dues, and mortgage insurance in the proposed housing payment when you want the ratio to reflect those costs. A lender may still count housing costs under its own rules.
Does a low DTI mean I will be approved?
No. A lower DTI can be a good sign, but approval can also depend on credit, income stability, down payment, loan type, cash reserves, documentation, property details, and lender rules. This calculator only checks the simple ratio from the numbers you enter.
What is the Debt-to-Income Ratio Calculator doing with my numbers?
In plain language: The calculator adds existing monthly debt payments and proposed housing payment, divides by gross monthly income, then converts the result to a percentage. For the default example, ($900 existing debts + $1,500 proposed housing) / $6,000 gross monthly income = 0.40, so the result is 40% DTI with $2,400 total monthly debt.
How should I read the Debt-to-Income Ratio Calculator answer?
Read the debt-to-income ratio first, then check total monthly debt and income after listed debts. The remaining-income line is not a full budget because it does not subtract taxes, groceries, utilities, savings, insurance, or irregular costs.
What does this estimate leave out?
This is a simplified planning ratio. It does not approve a loan, verify gross income, classify debts, split front-end and back-end ratios, include taxes, insurance, or HOA unless you enter them in housing payment, or replace lender underwriting. For a real loan or mortgage decision, compare lender definitions, front-end and back-end ratios, taxes, insurance, HOA dues, credit review, down payment, APR, and the written Loan Estimate or loan offer.
What should I double-check before copying the result?
Make sure all amounts are monthly, income is gross monthly income, existing debts are debt payments instead of total balances, and the housing payment includes escrow costs only if you want them in this estimate.
Does the site save my finance inputs?
No. The calculator runs in your browser tab. Recent answers stay only on the page while you use it, and they are not sent to a server.
