How we calculate DTI

DTI = (total monthly obligations / gross income) × 100%. Obligations include loan payments, leasing, minimum credit card payments and other regular debt.

Example: PLN 6,000 gross income, PLN 1,200 loan payment

Gross income PLN 6,000, mortgage PLN 1,200: DTI = 1200/6000 × 100 = 20%. Safe level, below 36%.
