How Each Split Mode Works
⚖️ Equal Split
Divides the total evenly among all people. Best for rent with same-size rooms, utility bills, or any expense where everyone benefits equally.
% Custom %
Each person pays a percentage of the total. Ideal for unequal rooms (60/40 rent split), or when income-based splitting is preferred. Percentages must sum to 100%.
🔢 Exact Amount
Each person enters exactly what they owe. Perfect for restaurant bills where people ordered different items. The amounts must add up to the total.
🍕 By Shares
Assign each person a number of shares (1, 2, 1.5…). The total is split proportionally. Useful when one person is covering more (e.g., 2 shares vs 1 share = pays double). Half-shares allowed.
🧾 Tip Splitter
Enter the bill subtotal, choose a tip % (5–20% or custom), add optional tax/GST, and get the full total. Then split equally or by custom percentage. Great for restaurant groups.
How to Split Rent Fairly
For equal rooms, split the total rent equally. For different room sizes, use Custom % — bigger rooms pay a higher share. Common splits for 2 flatmates: 60/40 or 55/45 for unequal rooms.
For utilities (electricity, water, internet), an equal split is usually fairest unless usage differs significantly — e.g., if one person works from home.
Want to track all of this automatically every month? FairShare for Roommates lets you set up recurring bills that auto-log every month.
