Tax on interest calculator
Type a gain and a rate. 500 at 19% gives 95,00 zł. 1000 at 19% gives 190,00 zł. 250 at 10% gives 25,00 zł. The same product as Belka, but you type the rate.
Not a filing. The calculator multiplies gain by a typed percent. Fixed 19% with net lives on Belka tax. We do not overwrite that page.

How it works
Tax on interest in this calculator is gain times rate over 100. 500 × 19% = 95. The result is 95,00 zł. 1000 × 19% gives 190,00 zł. 250 × 10% gives 25,00 zł. You type the gain, not the whole principal.
The gain field is the base. The rate field is a percent from your hands. 19 at 500 and at 1000 is an example, not an inserted Belka default. 10 at 250 also comes from the field, not from a statute.
The Belka card next door at 1000 and 19% shows 190 tax and 810 net. Here 1000 and 19% leaves only the result 190,00 zł. We do not touch that page.
Gain from a deposit lives first on the deposit card. Here interest already sits in the field, then times the rate. 500 gain at 19% is 95,00 zł of tax, not 95 from the whole deposit.
Type 500 and 19, then Calculate. A comma in 19.5 parses. A product sketch, not a tax form and not an office table.
500 at 19% gives 95,00 zł. 1000 at 19% gives 190,00 zł. 250 at 10% gives 25,00 zł. Another rate at the same gain gives another result.
Formula
tax = gain × (rate / 100)
