Debt load calculator

Calculate what share of monthly income is used by recurring debt payments.

Calculation parameters

Debt load

15000 / 50000 × 100 =
30%
30% share of income
# Income 50000
Debt payments 15000
= Income remaining after debt payments 35000
Formula: D / I × 100% D is monthly debt payments and I is monthly income
How it works The calculator divides recurring monthly debt payments by monthly income and converts the result to a percentage.

Explanation and example

The result is a mathematical share of income used by debt payments. For a consistent comparison, use income and payments from the same period and in the same currency.

For example, if monthly income is 50,000 and recurring monthly debt payments are 15,000:

15000 / 50000 × 100% = 30%
Debt load is 30%, and 35,000 remains after debt payments.
More examples 50,000 income and 15,000 payments → 30% 40,000 income and 10,000 payments → 25% 30,000 income and 0 payments → 0% 10,000 income and 12,000 payments → 120%
What does this calculator show?

It shows recurring monthly debt payments as a percentage of monthly income.

Which payments should I enter?

Enter the recurring monthly payments for loans and other debt obligations you want to include in the calculation.

Which income figure should I use?

Use one consistent monthly income figure. A bank or other institution may use a different income methodology.

Can the result be above 100%?

Yes. Mathematically, that means the entered monthly debt payments are greater than the entered monthly income.

Does this calculator predict whether a lender will approve a loan?

No. It only shows a mathematical ratio. Banks and other institutions can apply their own income definitions, additional expenses and threshold rules.
