ChoreLedger: Fair Chore Rota and Exact Allowance Split

Three children who did 70, 60 and 60 minutes of a 190-minute week are owed 552.63, 473.68 and 473.68 cents out of a $15.00 pot - and rounding each share separately hands out $15.01, a cent that does not exist. This splits the pot by the largest remainder method so the payouts always sum to the pot, and builds the rota by minutes rather than by headcount, with a guarantee it shows you being met: the busiest and the least busy child stay within one chore of each other.

Parents running a chore-and-allowance arrangement at home who want the split to be defensible to the children, and anyone dividing a fixed sum among people who did unequal amounts of work.

How it works

  1. Add each chore with how many minutes it takes and how many times a week it happens.
  2. Name the children, set the weekly pot and how many weeks to plan.
  3. Read the rota and the per-child totals: minutes, share of the work and what each is paid.
  4. Check the two lines that matter - the busiest-minus-least-busy gap, and that the payouts sum to the pot.

What you gain

  • Makes sure no child carries far more chore load than the others, and splits the allowance so the cents add up exactly to the total — no leftovers, no arguments about who got more.

Frequently asked questions

Does ChoreLedger store my family's chore data on a server?

No — all chore and allowance data is processed locally in your browser. Nothing is uploaded or stored externally.

Can ChoreLedger handle an uneven number of chores or children?

Yes — it balances by minutes, not headcount, and the allowance split works for any number of children, always summing to the exact pot.

Does ChoreLedger guarantee the fairness it claims?

It shows the stated guarantee on screen: the gap between the busiest and least busy child never exceeds the single longest chore, and it displays this being met for your plan.
