Whether it's a dinner, rent, or a whole trip, splitting bills comes down to three things: how you split, who paid, and who owes who. Here's the simple version — plus free calculators and an app that does the math for you. No bank account needed.
The simplest and fairest for a shared meal or cost — divide the total by the number of people. Try the bill split calculator.
When people used different amounts — a bigger room, unequal portions — give each a weight so it stays fair. See the rent split calculator.
Everyone had something different? Assign each item to whoever had it. Duesy supports exact, per-item and unequal splits in-app.
For a trip or shared house, log every expense and let the app net it out. Try the who-owes-who calculator.
Total the bill, including anything shared.
Evenly, by shares, or itemized — whatever's fair.
Their balance is what they paid minus their share.
See who owes who and pay in the fewest transfers.
The mistake most groups make is trying to even things out at every meal. It's slow, and someone always forgets. The easier way: let anyone pay for anything as you go, record each expense with who paid, and settle up once at the end. A running "who owes who" means no mental math and no awkwardness.
That's exactly what Duesy does. Add friends, roommates or a whole trip group by link or QR — even people who aren't on Duesy yet — log expenses in any currency, and it keeps everyone's balance live. When it's time to settle, it shows the fewest payments to make everyone even. It's free, with no daily limit on expenses, and it never asks you to link a bank account.

For a shared cost, an even split is fairest and simplest. When people clearly had different amounts — a bigger room, a much larger order — split by shares or itemize so everyone pays for what they used. Either way, record who paid so balances stay correct.
Each person's balance is what they paid minus their fair share. Whoever paid more is owed; whoever paid less owes. Duesy tracks this live across many expenses and shows the fewest payments to settle everyone up.
In Duesy you can add someone even if they're not on Duesy yet, and share a group by link or QR — no usernames. Or use the free calculators here without signing in at all.
