19.99 divided by three.
Who gets the extra cent?
Agree on the split, then make the numbers add up. Compare equal shares or simple weights without creating an account or entering anyone’s payment details.

THE INTERACTIVE WORKSPACE
Allocate a single charge
Use the same weight for equal shares. A weight of 2 gets twice the share of a weight of 1. Set a person’s weight to 0 to exclude them. Weights are an agreement you supply, not a fairness score.
USE IT IN REAL LIFE
Agree on the rule before the arithmetic.
Equal shares: use weights 1, 1, 1. For 19.99, one person pays 6.67 and two pay 6.66. The extra cent is not an extra fee.
Weighted shares: use 2, 1, 1 if the agreed split is one half, one quarter, one quarter. With 20.00, the shares are 10.00, 5.00 and 5.00. The tool does not decide whether usage, income or another factor should determine those weights.
It first rounds every proportional share down to whole cents, then gives leftover cents to the largest fractional remainders. Ties go in A–D order. That tie-break is deterministic, not inherently fair; you can rotate who occupies each letter on future charges.
Use the actual full charge for one billing period, including any agreed taxes or fees. Do not mix currencies or assume a person’s transfer changes the provider’s bill. Refunds, missed payments and changes in membership need a separate agreement.
THE NEXT STEP
Keep the renewal visible after the split is agreed.
MoneyShield tracks recurring charges, renewal dates and cancel-by reminders. Keep the provider’s full charge distinct from any private reimbursement arrangement. This browser split calculator is not an in-app shared-payment feature.
