When to use it
Split agreed expenses for people sharing the same journey. Enter a known fuel or charging amount rather than recalculating vehicle consumption. The USD figures are simulated. Count everyone paying an equal share, including the driver if the driver also contributes.
Inputs
USD
| Inputs | Default |
|---|---|
| Fuel/charge | 30 |
| Tolls | 12 |
| Parking | 6 |
| People | 3 |
Calculation method
Add fuel or charging, tolls and parking to get shared expenses. Divide the total by the number of contributors. The example has USD 48 of costs shared by 3 people, or USD 16 each.
30 [Fuel/charge] + 12 [Tolls] + 6 [Parking] → Shared total
Shared total/3 [People] → Each share
Change one input
Change the contributor count from 3 to 4. The same total is split four ways; the costs themselves do not change.
| Result | Default | Changed |
|---|---|---|
| Shared total | 48 | 48 |
| Each share | 16 | 12 |
Results are displayed to at most two decimal places; later formulas use unrounded values.
Scope and limits
- Contributors must be a positive whole number; expense amounts must be nonnegative.
- Include the driver only when sharing the cost.
- Equal shares assume the same agreed expenses and journey for everyone.
This is a theoretical equal share, not a record of who owes whom after prior payments. Different pickup points, unequal usage, personal expenses and driver compensation require a different agreement. Displayed shares may not sum exactly to the total after rounding; agree who covers any smallest-unit remainder.

Common questions
Should I enter passengers or everyone in the car?
Enter people contributing equally. Three passengers plus a contributing driver means 4; a driver who pays nothing is not counted.
What if one person already paid everything?
Each share shows that person’s own expense too, if counted. Reimbursements must account separately for amounts already paid; do not ask the payer to pay their share twice.
