Tip Calculator

End the awkward phone-passing at dinner.

Nobody wants to do percentage math over appetizers. This tip calculator gives you the tip amount, the total, and the per-person split the second you type. Quick buttons for the common 15/18/20/25% rates handle most situations; the custom field handles the rest — from coffee-shop rounding to large-group celebrations.

Why people use this

The most everyday calculator there is: splitting dinner with friends, tipping on a haircut, working out the delivery tip in the rain. People use it because nobody wants to do percentage math at the table — and because the "split 5 ways with 18%" answer needs to be instant.

How it works

1. Enter the bill amount before tip.
2. Pick a tip percentage with the quick buttons or type a custom one.
3. Set how many people are splitting the bill (1 if it is just you).
4. Read the tip amount, total, and per-person cost instantly.

Common questions

Is 15% still a standard tip?

In the US, 18–20% is now the common range for sit-down restaurants, with 15% seen as the minimum for acceptable service. For delivery, bartenders, and baristas, norms vary — $1–2 per drink or 10–15% is typical.

Should I tip on the pre-tax or post-tax amount?

Etiquette guides say pre-tax, and that is what this calculator uses by default. The difference on most bills is small enough that nobody will fault you either way.

How do I split a bill fairly when people ordered differently?

This calculator splits evenly. For uneven orders, each person can run their own subtotal plus shared items divided by the group, then add their proportional tip percentage.
