Tip on the subtotal
A $50 subtotal, 10% tax, and 20% pre-tax tip creates $5 tax and a $10 tip. The final total is $65. Split between two people, each pays $32.50.

Direct answer
How to calculate a tip and split the bill
Multiply the chosen tip base by the tip percentage, add the tax and tip to the bill, then divide the final total by the number of people. For a pre-tax tip, the base is the bill subtotal. For an after-tax tip, the base is the subtotal plus tax.
With the default example, an $86.40 subtotal and 8.25% tax produce $7.13 in tax. A 20% pre-tax tip is $17.28. The exact total is $110.81, so three people pay $36.94 each before any optional round-up.
| Result | Formula | What it means |
|---|---|---|
| Tax | subtotal × tax rate | Optional tax not already included in the entered bill |
| Tip | tip base × tip rate | The base is either subtotal or subtotal plus tax |
| Total | subtotal + tax + tip + round-up | The amount the whole group pays |
| Per person | final total ÷ people | Equal split; individual orders are not itemized |
Tip after tax
On the same $50 subtotal and 10% tax, a 20% after-tax tip uses $55 as the base. The tip is $11, the total is $66, and two people pay $33 each.
Round each share
If the exact split is $27.68 each, “Round each” makes every share $28. The receipt shows the combined round-up so the displayed shares still equal the displayed total.
Before you add another tip
Look for “service charge,” “gratuity,” or a percentage already printed on the receipt. An included charge is not automatically identical to a voluntary tip, and policies vary by business. The calculator cannot inspect your receipt, so include only amounts you intend to add.
Tipping customs depend on location, service type, and personal choice. The preset buttons are arithmetic shortcuts, not a statement that a particular rate is required. When traveling, confirm local practice and whether service is already included.
What this calculator does—and does not do
- Calculates an equal split from one subtotal, optional tax, and one tip rate.
- Shows whether the tip is based on the subtotal or the after-tax amount.
- Reconciles total or per-person round-up with a visible adjustment.
- Does not itemize unequal orders, scan receipts, move money, or convert exchange rates.

Frequently Asked Questions
Should I calculate the tip before or after tax?
Either choice is mathematically valid. Many people use the pre-tax subtotal as the tip base, while some payment screens calculate suggestions from the after-tax amount. This calculator labels the selected basis so you can make that choice explicitly.
How do I split a bill with a tip?
Add the subtotal, tax, and tip first, then divide the final total by the number of people. The calculator also shows the tip per person and keeps any rounding adjustment visible.
What does round each person up do?
It rounds every person’s share up to the next whole currency unit, then multiplies that clean share by the group size. The extra amount is shown as a round-up adjustment so the receipt still reconciles.
Does the currency selector convert exchange rates?
No. It changes the currency symbol and number formatting only. Enter every amount in the same currency; no exchange-rate conversion is performed.
What if the bill already includes tax or a service charge?
Leave the tax rate at zero when tax is already included. Check the receipt for an automatic gratuity or service charge before adding another tip, because this calculator does not detect charges that are already on the bill.
