Your debt-to-income ratio (DTI) is your monthly debt payments divided by your gross monthly income. Lenders use it to judge how much more you can afford to borrow.

Also called: DTI calculator.

## Inputs
- Gross monthly income (before tax) (default 6000)
- Rent or mortgage payment (default 1500; optional)
- Car loan payments (default 400; optional)
- Student loan payments (default 200; optional)
- Credit card minimum payments (default 100; optional)
- Other debt payments (default 0; optional)
- DTI to compare against (unit %; default 36)
- Currency

## Results
- Debt-to-income ratio (back-end)
- Housing ratio (front-end)
- Total monthly debt payments
- Room left before the comparison DTI

## Formula

```
Back-end DTI = Total monthly debt payments ÷ Gross monthly income × 100;  Front-end = Housing payment ÷ Gross monthly income × 100
```

Where:
- Debt payments: required minimum monthly payments, not living costs like food or utilities
- Gross income: income before tax and deductions

## Worked example
1. Total debt payments = 1,500 + 400 + 200 + 100 = $2,200.
2. Back-end DTI = 2,200 ÷ 6,000 = 36.67%; front-end = 1,500 ÷ 6,000 = 25%.
3. At 36%, payments could total 6,000 × 0.36 = $2,160, so you are $40 over.

**Result:** With $2,200 of monthly debt payments on $6,000 of income, your DTI is 36.67%, just above a 36% benchmark.

## What the result means

A lower DTI means more of your income is free, which makes approval and better rates more likely. Paying off a small loan entirely lowers DTI more than paying down a large one.

## Assumptions and limits
- Only required monthly debt payments count; living expenses are excluded.
- Lenders differ on what counts as income and debt (for example, how they treat student loans in deferment); their figure can differ from yours.

## Questions

### What DTI do lenders want?

It depends on the lender and the loan program, so ask. Many lenders consider a lower DTI less risky, and some programs set a published maximum.

### Does rent count?

Your current rent is part of your housing payment for your own budgeting. When you apply for a mortgage, the lender uses the proposed new housing payment instead.
