How to split a bill fairly: tips, service charge and trip expenses
Splitting a bill sounds like simple division until someone didn't drink, someone ordered the expensive dish, or the shares don't divide neatly. A few plain rules keep the sums right and the friendship intact.
The simple equal split
When everyone shared roughly the same, an equal split is the fairest choice, and the quickest.
Tip = bill × tip % ÷ 100
Each person's share = (bill + tip) ÷ number of people
Example: a ₹2,450 bill, a 10% tip and 4 people. The tip is ₹245, the total is ₹2,695, and each person pays ₹673.75.
What to do with the leftover paise
Some totals don't divide exactly. ₹1,000 between 3 people is ₹333.33 each, which only adds up to ₹999.99. One person has to pay the extra paisa: ₹333.34, ₹333.33 and ₹333.33. Our Bill Splitter does this for you, so the shares always add up to the exact total.
In practice, most groups round each share up to the nearest ₹5 or ₹10 and add the difference to the tip. That is easier to send by UPI, and nobody will miss it.
When an equal split isn't fair
If orders were very different, split the shared items equally and let each person pay for their own. Add tax in proportion at the end.
Example: three friends share starters worth ₹900, so that is ₹300 each. Their own orders were ₹400, ₹250 and ₹350. The food comes to ₹1,900, and the bill adds 5% GST, which is ₹95.
| Person | Shared | Own order | Food total | With 5% GST |
|---|---|---|---|---|
| Asha | ₹300 | ₹400 | ₹700 | ₹735 |
| Ravi | ₹300 | ₹250 | ₹550 | ₹577.50 |
| Meena | ₹300 | ₹350 | ₹650 | ₹682.50 |
| Total | ₹900 | ₹1,000 | ₹1,900 | ₹1,995 |
Our Bill Splitter handles equal splits only, so use this method for unequal ones.
Tips and service charge
A tip is your choice. A service charge added to the bill is also your choice, whatever the menu says. Guidelines from the Central Consumer Protection Authority, issued in 2022, say restaurants and hotels should not add a service charge automatically or by default. The Delhi High Court upheld them in March 2025, and the authority has continued to act on complaints since then.
- Check the bill before you split it, because a service charge can be easy to miss.
- If you don't want to pay it, ask for it to be removed. A restaurant can't refuse entry or service because of this.
- If they refuse, you can call the National Consumer Helpline on 1915 or file a complaint through its website.
- If you do want to tip, work it out on the food total rather than the total with tax. Otherwise you are tipping on the GST as well.
Settling up after a trip
On a trip, different people pay for different things. Don't settle each expense on its own. Work out one balance per person instead, which means far fewer payments.
- Add up everything the group spent, and divide by the number of people to get the fair share.
- For each person, subtract the fair share from what they paid.
- Those with a minus balance pay those with a plus balance.
Example: four friends spend ₹12,000, so the fair share is ₹3,000 each.
| Person | Paid | Balance | What happens |
|---|---|---|---|
| Asha | ₹6,000 | +₹3,000 | Receives ₹3,000 |
| Ravi | ₹3,000 | ₹0 | Nothing to do |
| Meena | ₹2,000 | −₹1,000 | Pays Asha ₹1,000 |
| Kabir | ₹1,000 | −₹2,000 | Pays Asha ₹2,000 |
Two payments settle everything. Send them by UPI with a note like "Goa trip" and check the name before you confirm, so everyone has a record. Agree this on the last day of the trip, while everyone still remembers who paid for what.
