Free online calculators for Poland

Liczbnik.pl is a collection of 575+ free online calculators built for Polish rules: current PIT rates, ZUS contributions, VAT rates and the limits that apply in 2026. Every calculation runs in your browser — no sign-up and no data collection.

Finance tools are the most popular: the gross to net salary calculator shows what actually lands in your account on an employment contract, a contract of mandate or B2B, and the VAT calculator converts net and gross amounts at 23%, 8% and 5%. Planning to buy a flat? Check the mortgage calculator with equal and decreasing instalment schedules.

Beyond finance you will find health calculators (BMI, calorie needs), maths tools, unit converters and calculators for working days or travel costs. Each calculator explains its formula, shows a worked example and answers the most common questions.

We keep rates and regulations up to date and describe how we calculate in our methodology. Results are indicative — for important financial decisions consult an adviser or an accountant.
