What is this tool?
The PayBack Calculator is a simple tool for settling shared spending. Instead of manually checking every receipt and doing the math in chat, you enter each payment and let the calculator show the cleanest payback plan.
It is useful when one person paid for several people, when multiple people paid different amounts, or when a group wants a fair result after food, fuel, room booking, supplies, or team activity costs.
Why use this tool?
- It reduces awkward money conversations by showing clear payback amounts.
- It works well for meals, trips, office events, and small project expenses.
- It avoids spreadsheet setup when you only need a quick split.
- It helps Khmer and English speaking teams keep shared costs transparent.
- It keeps the result focused on who pays who, not on complex accounting.
