Question 1

How much is a 15% tip?

Accepted Answer

Multiply the pre-tax subtotal by 0.15. $20 bill → $3.00 tip → $23.00 total; $50 bill → $7.50 tip → $57.50 total; $100 bill → $15.00 tip → $115.00 total. TipSplit rounds to the nearest cent.

Question 2

Is 15% still an acceptable restaurant tip?

Accepted Answer

In much of the US, 15% now reads as the low end of sit-down service — fine for casual lunch or uneven service, thin for a full-service dinner where 18–20% is the usual ask. Customs vary by city and by whether the server is tipped-wage. If a printed suggested tip starts at 18% or 20%, that is the house telling you their norm, not a law.

Question 3

When did 15% stop being the default?

Accepted Answer

There is no single year. Credit-card receipts in the 1990s often printed 15 / 18 / 20. By the mid-2010s many terminals started at 18 or 20. The math never changed; the social default did. This page exists because people still search “15 percent tip” when they want the older number, not a lecture.

Question 4

Should I tip 15% before or after tax?

Accepted Answer

US restaurant habit is to tip on the pre-tax subtotal. A 15% tip on an $80 subtotal is $12 whether sales tax is 0% or 10%. Tipping after tax quietly raises the rate. Use the pre-tax / post-tax toggle if your receipt only shows a total.

Question 5

Does 15% work for haircuts or delivery?

Accepted Answer

Sometimes. Hairdressers and delivery drivers often see 15% as a floor rather than a compliment. Short rides and small delivery orders are often easier as a dollar minimum ($3–$5) than as a percentage. Open the matching how-much-to-tip page if you want the range for that job.

Question 6

How do I split a 15% tip evenly?

Accepted Answer

Compute tip and total first, then divide the total by the number of people. Leftover cents (when the total does not divide cleanly) stay on the last share so the table still adds up. This MVP splits equally only — itemized “I only had the salad” is a later tool.
