How do I calculate a 20% tip?

Move the decimal point one place left to get 10%, then double it. For a $65 bill: 10% = $6.50, doubled = $13.00 tip. Or just use this calculator — enter 65 and select 20%.

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

Convention varies by country. In the US, tipping on the pre-tax subtotal is common, though tipping on the full post-tax total is also accepted. Enter whichever figure you prefer — the tool uses exactly what you input.

Can I enter a custom tip percentage?

Yes — select Custom % and enter any percentage from 0 upward. Useful for rounding to a specific total or tipping an exact dollar amount.

What does the per-person amount include?

Per person = (bill + tip) ÷ number of people. It is the total each person should contribute, including their share of the tip.

How do I split the bill unevenly?

This tool divides equally. For uneven splits (different dishes, different people paying different amounts), calculate each person's subtotal separately and add their share of the tip proportionally.

What Is a Tip Calculator?

A tip calculator computes the tip amount, total bill and per-person split for any bill size and tip percentage. Instead of doing mental arithmetic at the table — especially after a few drinks — enter the bill total, choose your tip percentage and the number of people splitting, and get the exact amounts instantly. Useful for restaurants, taxis, delivery, hotel staff and any other service where gratuity is expected or appreciated.

Tipping Etiquette by Country

Country	Typical Restaurant Tip	Notes
USA / Canada	15–20%	Expected; 18% is now considered standard
UK	10–15%	Optional if a service charge is already included
Australia	10%	Appreciated but not mandatory
Europe	5–10%	Round up the bill or leave small change
Japan / China	0%	Tipping is uncommon and can be considered rude
Middle East	10–15%	Expected in tourist restaurants; check if included

How the Tip and Split Are Calculated

The tool calculates: tip = bill × (tip% ÷ 100), then total = bill + tip, and finally per person = total ÷ number of people. Rounding is applied to 2 decimal places for display only — all intermediate calculations use full precision to avoid rounding errors accumulating across the split.

Common Tip Percentages at a Glance

10% — move the decimal point one place left: 10% of $48.50 = $4.85
15% — find 10%, then add half: 10% = $4.85 + 50% of that = $2.43 → $7.28
20% — move the decimal and double: 10% of $48.50 = $4.85 × 2 = $9.70

Watch Out for Service Charges Already on the Bill

Many restaurants — particularly in the UK, Europe and tourist areas worldwide — add a service charge (typically 10–15%) automatically to the bill. Before tipping, check the receipt for lines labelled "service charge", "gratuity included" or "service compris". If a service charge is already included, tipping again is optional and at your discretion — you are not obligated to tip twice. In the US, this is common for large groups (6 or more diners) where an automatic gratuity of 18–20% is often added by default.
