Bill, Tip & Tax Splitter

How this calculation works

Splitting bills with friends gets messy without a clear calculator. This tool gives everyone a fair per-person amount in seconds — no more mental math or spreadsheet arguments at the table.

Keep in mind that some restaurants add an automatic 18-20% gratuity for parties of 6 or more. Check your bill carefully to avoid double-tipping.

How this Bill, Tip & Tax Splitter works — 2026 guide

Dinner for six means tip, tax, and who-ordered-what all collide at once. This bill, tip and tax splitter takes the subtotal, applies the tip rate you choose (15% baseline, 18% typical, 20% for great service — and yes, many people tip on the pre-tax subtotal), adds the sales tax, and divides the total evenly or by the exact amounts each person owes. No more calculator fights at the table.

How to use it in 3 steps

1. Enter the bill subtotal and the sales tax rate.
2. Choose a tip percentage (15/18/20 or custom) and whether the tip is calculated pre- or post-tax.
3. Split evenly by number of people, or enter each person's individual share for unequal orders.
