Prorated Tracker
Split expenses based on how many days each person is around — ideal for trips with late arrivals or early departures.
What is a Prorated Tracker?
A Prorated Tracker splits expenses based on how many days each person is present, so everyone pays their fair share. Someone who joins a trip three days late pays less for shared costs like accommodation.
To create one, select By Attendance as the splitting method when setting up a new tracker. You'll need to set Period Dates (a start and end date) — Tabello uses these to calculate each person's share based on the days they're around.
How It Works
Tabello does not assign expenses to specific days. Instead, it looks at the sum of all daily weights for every participant to create a single, final allocation ratio for the entire tracker.
How allocation ratios work
If a trip lasts 10 days and a participant is set to 100% for 5 days and 0% for the other 5, their total weight is 5. If another participant is at 100% for all 10 days, their weight is 10. The first person will be responsible for 1/3 of the total expenses incurred during the trip, regardless of which day those expenses were paid.
Setting Daily Presence Weights
By default, every participant is set to 100% for the entire period. Adjust individual days for late arrivals, early departures, or partial days (e.g., 50% for arriving mid-day).
A Daily Presence Weight of 50% means that person benefited half as much as a full-day participant on that day. Set it to 0% for days they weren't there at all.
Adding Expenses
Adding expenses works the same way as a Regular Tracker — enter a name, amount, who paid, and an optional category. The difference is how the split is calculated: instead of dividing evenly, Tabello uses each participant's daily presence weights to determine their share.
What Happens When Dates Change
Changing the tracker's Period Dates or any participant's Daily Presence Weights triggers automatic reallocation of all expenses. Balances and the Settle Up plan are recomputed instantly.
