Frequently Asked Questions
Can it handle complex splits with multiple advance payments?
Yes. Even when several people paid for different things — one covered dinner and another covered drinks — enter each member’s advance in the “With Advances” section, and the tool calculates exactly who should pay whom to settle up.
How are remainders handled?
Any amount that doesn’t divide evenly by the rounding unit is automatically assigned to the first few members, one unit each, so the parts always add up to the exact total. Choose “None” as the rounding option to split down to the smallest unit.
How do I share the result in a group chat?
Press the “Copy as Text” button after calculating. The per-person amounts and the settlement flow are copied as plain text, ready to paste into any group chat or messaging app.
Can I split unevenly, such as seniors paying more?
For weighted splits by a ratio such as 2:1, try the Ratio Split Calculator. Enter the total and the ratio, and it calculates each person’s weighted share automatically.
