Sum Split Bill Calc

Split any bill in seconds. Tip guide included.

Sum makes splitting the bill the easiest part of any meal. Whether you are at a restaurant with friends, sharing a rideshare, splitting a hotel room, or ordering food delivery, Sum calculates exactly how much everyone owes in seconds.

Enter your total, choose a tip percentage from the quick-tap buttons (10%, 15%, 18%, 20%, or 25%), set the number of people, and Sum instantly shows the per-person amount alongside a full breakdown of subtotal, tip, and grand total.

Every split you save goes into History so you always know who paid what and when. Browse past splits by place, date, total, and per-person cost — and swipe to delete any entry you no longer need.

The built-in Tip Guide takes the guesswork out of tipping. See the recommended tip range for seven different service categories: restaurants, takeout, bars, hair and beauty salons, rideshare, hotel housekeeping, and food delivery. Each category includes a short note explaining the standard so you always tip with confidence.

Sum is built for speed. No accounts, no sign-ups, no internet connection required. Your history is stored privately on your device. The vibrant orange interface is designed for readability in any lighting — at the dinner table, in the car, or at the hotel checkout desk.
