About this calculator
Split shared trip expenses fairly among travelers, accounting for unequal nights stayed and a shared pool of common costs like gas and groceries.
Frequently Asked Questions
How do partial stays get handled?
This calculator divides total lodging cost by total traveler-nights (accounting for anyone who missed nights), then multiplies by the full trip length to find what a full-stay traveler owes, so partial guests pay proportionally less.
What counts as a shared expense?
Anything the group pools together and splits evenly regardless of stay length, like a shared rental car, groceries, or group activity tickets.
Can I use this for trips with very uneven stays?
Yes, just make sure to total up all the traveler-nights missed across everyone with a shorter stay and enter that combined number.
