Common questions
Yes. Switch to "Total cost" and enter the amount you want to split.
With no rounding we split to the exact penny: if it doesn't divide evenly, one or two people pay 1p more so the total is covered exactly. You can also round each share up to the next 50p or £1; we show how much extra that collects.
Only if you are calculating from distance and fuel price. Total cost splitting does not need MPG.
Make splitting fair
For mixed journeys, agree the rounding setting up front and share the exact per-person result to avoid confusion. You can also compare fuel prices along your route to reduce the total bill.
