Frequently Asked Questions

Q. Equal vs per-item split?

Equal split divides the total by headcount. Per-item charges only what each person ordered — fairer when some skipped drinks or shared dishes.

Q. One person paid the whole bill — what now?

Designate the payer; the calculator tells everyone else how much to transfer back. Ready to message via chat apps.

Q. How to handle partially-shared dishes?

Tag a dish as "shared by N people" — it auto-splits among them.

Q. What about rounding leftovers?

Round per 100-won unit; the payer usually absorbs the tiny difference. The calculator lets you choose who covers leftovers.

Q. How is this different from KakaoTalk's split?

KakaoTalk only does equal splits. This tool handles per-item, partial shares, taxes, and exports a clean per-person summary.

Q. Is the payment data saved?

No. Everything runs in your browser and disappears when you close the page.
