Splitting a check evenly is quick, but it isn’t fair when one person had a salad and water and another had the steak and two cocktails. This calculator splits the bill the way most people consider fair: everyone pays for what they ordered, shared dishes are divided equally, and tax and tip are shared in proportion to each person’s subtotal.
How to use the split the bill calculator
- List each person and the total of what they ordered, one per line, with the amount last — for example “Priya 27.25”.
- Enter the cost of shared items — appetizers, a bottle of wine, desserts — to be split evenly among everyone.
- Enter the tax as a percentage, or switch to $ total and type the tax from the receipt.
- Enter the tip percentage. Leave tip on the after-tax total unchecked to tip on food and drink only.
- Read each person’s total on the tape and the full breakdown in the table.
Split bill formulas
Worked example
Four friends share $36 of appetizers. Alex’s own order was $24.50, Jordan’s $31.00, Sam’s $18.75 and Priya’s $27.25. Tax is 8.25% and they tip 20% on the pre-tax subtotal.
Subtotal = 101.50 individual + 36.00 shared = $137.50; shared items are $9.00 each
Tax = 137.50 × 8.25% = $11.34; tip = 137.50 × 20% = $27.50; grand total = $176.34
Alex's subtotal is 24.50 + 9.00 = $33.50, or 24.36% of the bill, so Alex pays 33.50 + 2.76 tax + 6.70 tip = $42.96
| Person | Own items | Shared | Tax | Tip | Total |
|---|---|---|---|---|---|
| Alex | $24.50 | $9.00 | $2.76 | $6.70 | $42.96 |
| Jordan | $31.00 | $9.00 | $3.30 | $8.00 | $51.30 |
| Sam | $18.75 | $9.00 | $2.29 | $5.55 | $35.59 |
| Priya | $27.25 | $9.00 | $2.99 | $7.25 | $46.49 |
| Total | $101.50 | $36.00 | $11.34 | $27.50 | $176.34 |
An even split would have charged everyone $44.09: Sam would have overpaid by $8.50 and Jordan underpaid by $7.21.
Fair-splitting tips
Decide on shared items first
Agree at the table which dishes are shared. Anything not on that list goes on the person who ordered it.
Tip on the pre-tax amount
Etiquette guides generally suggest tipping on the food and drink subtotal. Tick the after-tax option only if your group prefers to tip on the full check.
Watch for automatic gratuity
Many restaurants add a service charge for larger parties. If the receipt already includes one, set the tip to 0 so you don’t tip twice.
Use it beyond restaurants
The same method works for shared groceries, vacation rentals with different-sized rooms, or a road trip where one person drove only part of the way. For trip fuel costs, the gas mileage calculator estimates the total to split.
For a simple even split with rounding, the tip calculator is faster.
Results are rounded to the cent so the shares add up exactly to the bill; treat them as a fair estimate rather than an accounting record.
Frequently asked questions
How do I split a bill when people ordered different amounts?
Add up what each person ordered, split any shared dishes evenly, then divide the tax and tip in proportion to each person's share of the subtotal. Someone whose food was 25% of the subtotal pays 25% of the tax and tip.
Why split tax and tip proportionally instead of evenly?
Tax is charged on what each person ordered, and the tip is usually a percentage of the food and drink. Splitting both evenly would make the person with a side salad subsidize the person with a steak.
How does the calculator handle rounding?
It works in whole cents and uses the largest-remainder method, so the individual shares always add up to the exact bill total. Occasionally one person pays a cent more than a straight proportional split would suggest.
Can I enter tax as a dollar amount?
Yes. Switch the tax field from % to $ total and enter the tax printed on the receipt. The calculator then splits that exact amount.
