Designing Dynamic Splits for Fairness

Not every split is equal. Sometimes one person uses more, another has a discount, or someone only participates part of the month. Splitify supports equal shares, fixed amounts, percentages, and combinations—so your group can be fair without a spreadsheet.

Equal, fixed, or percentage

Equal works well for shared utilities or subscriptions. Fixed is great when someone covers a base fee. Percentage fits variable usage or income-based fairness.

Real-world examples

• Roommates + couple: Four roommates, two of whom share a room. Give the couple a larger combined share with percentages while keeping others equal.
• Gym membership: One person uses premium classes. Assign them a fixed add-on, then split the rest equally.
• Partial month: A friend stays half the month. Set their share to 50% for that cycle.

Edge cases considered

Rounding, partial participants, and minimums are handled consistently so totals always add up. Mixed methods are calculated in a predictable order and shown to everyone.

Clarity for everyone

Participants see their amount and how it was calculated. This reduces back-and-forth and builds trust—especially helpful for recurring bills.

Tips for fairness

• Agree on a simple rule before money is involved.
• When in doubt, show the math in the request note.
• Revisit splits if living situations change (new roommate, move-out, etc.).

However you split, Splitify makes the math clear and the follow‑through automatic. Give it a try with your next bill.
