How are złote and złotych chosen?

The złoty noun follows the 1-2-5 rule. 1 złoty, 2-4 złote (e.g. 22 złote), and 5 or more złotych. The teens 12-14 take złotych. Zero złotych is the standard empty form.

Why are grosze written as digits?

Polish invoices and cheques conventionally spell the złoty part in words and write the grosze as two digits followed by the correct grosz form, for example 56 groszy. This avoids ambiguity in the fractional part.

Can I use a dot instead of a comma?

Yes. Both 1234,56 and 1234.56 are accepted. Spaces used as thousands separators are ignored, so 1 234,56 also works.

What is the largest amount supported?

Amounts up to 999,999,999,999.99 PLN are supported, covering everyday and large commercial invoices. Values are rounded to two decimal places.

Does the amount get uploaded?

No. The conversion runs locally using a built-in Polish number grammar, so the figures never leave your browser.

On Polish invoices, cheques and contracts the amount is written out słownie (in words) to prevent tampering. This tool spells any PLN sum with the correct złoty / złote / złotych agreement and the matching grosz / grosze / groszy form for the fractional part.

How it works

The amount is split into złote (whole part) and grosze (the two-digit remainder). The złote count is spelled in full Polish words, then the currency noun is chosen with the 1-2-5 rule:

1                          → złoty
2-4 (not 12-14)            → złote
0, 5-21, 12-14, ...        → złotych

The grosze follow the same rule for grosz / grosze / groszy but are written as two digits, matching standard Polish bookkeeping style. The fractional part is rounded to two places, and a value that rounds up to 100 grosze correctly rolls into one more złoty.

Example and notes

1234,56 becomes tysiąc dwieście trzydzieści cztery złote 56 groszy. 1,00 is jeden złoty 00 groszy, 5,02 is pięć złotych 02 grosze, and 21,00 is dwadzieścia jeden złotych 00 groszy (because 21 takes the many form). Use the output verbatim in the słownie field of an invoice.
