TripMath - Split Group Expense

Trip expenses, minus the spreadsheet.

TripMath is built for one thing: money between people on a trip. Track it, split it, settle it. No group-chat math, no shared spreadsheet nobody keeps up to date.

JUST SAY WHAT YOU SPENT

Type an expense the way you'd say it: "I paid $40 for dinner," "Jewel paid $120 for the hotel." TripMath reads the payer, the amount, and what it was for, and splits it across the group. No forms to fill unless you want them.

SPLIT IT ANY WAY THAT'S FAIR

Equal, exact amounts, percentages, or shares. Pick per expense. Someone skipped the drinks? Adjust the split without redoing the math. Shares always add up to the total, to the cent.

REAL MULTI-CURRENCY

Each trip has one home currency, but you can enter an expense in any of 150+ currencies. TripMath converts at a live rate, locks it in, and keeps balances separated by currency, so a trip across borders still balances perfectly.

SCAN RECEIPTS

Snap a receipt and TripMath pulls out the total to start the expense. No typing the numbers.

BALANCES & SETTLE UP

See who paid, who owes, and who should get paid back at a glance. TripMath suggests the simplest set of payments to square everyone up, fills in the amounts, and you mark them paid as you go.

BRING THE WHOLE GROUP

Invite by link, QR code, or email. Everyone previews the trip before they join. Save your regular travel crews as reusable Groups so you're not re-inviting the same friends every trip.

A COVER FOR EVERY TRIP

Give each trip a photoreal AI cover of its destination, generated on demand right from the create screen.

NEVER LOSE TRACK

Every add, edit, and settle is timestamped in a searchable activity feed, and deleted expenses can be restored for 30 days. Invites and settle-up reminders land in one inbox with a badge, so nothing slips.

WORKS OFFLINE

Airplane mode, foreign SIM, dead zone on a hike: keep adding expenses. TripMath syncs the moment you're back online.

SIGN IN, SIMPLY

Google, Apple, or a one-time email code. Everyone on a trip has an account, so names, balances, and who-paid-what stay accurate. No mystery "ghost" members.

FREE TO USE

Run up to 3 ongoing trips with unlimited expenses, all split types, currency conversion, receipt scanning, and AI trip covers. No ads, ever.

TRIPMATH PASS

Best part: when a Pass subscriber creates a trip, that trip is premium for everyone in it. Your friends get the upgraded experience without each buying their own.

Perfect for vacations, group getaways, road trips, bachelor and bachelorette weekends, family tours, business travel, backpacking, and every "we'll sort it out later" that never gets sorted.

Whether you're splitting a hotel, a dinner, a rental car, or the whole trip, TripMath does the math so the group stays fair and the friendships stay intact.
