Calculate a tip, total bill, and equal per-person split using a preset or custom percentage, with optional pre-tax tipping and transparent split rounding.
Multiply the amount being tipped by the tip percentage divided by 100. Add that tip to the entered bill total, then divide by the number of people for an equal split.
CalcRocket keeps the exact tip separate from any optional per-person rounding adjustment, so rounding never silently changes the stated gratuity.
tip = tip basis × (tip percentage ÷ 100)total = entered bill + tiptotal per person = total ÷ number of peopletip per person = tip ÷ number of peoplepre-tax subtotal = bill − tax amountpre-tax subtotal = bill ÷ (1 + tax rate ÷ 100)adjustment = rounded amount per person × people − exact totalA $100 bill with a 20% tip has a $20 tip and $120 total. Split four ways, each person pays $30, including $5 tip.
A $86.40 bill with a 20% tip has a $17.28 tip and $103.68 total. Split three ways, each person pays $34.56, including $5.76 tip.
A $75 bill with 0% tip remains $75. Split three ways, each person pays $25.
For a $108 tax-inclusive bill containing $8 tax, a 20% pre-tax tip uses a $100 basis. The tip is $20 and the $128 final total is $32 each for four people.
An exact $101 total split four ways is $25.25 each. Rounding each share upward to $26 produces a $104 group total and a separate $3 adjustment.
Tipping customs differ by place, service, and circumstance; the calculator does not prescribe a universal percentage.
Confirm whether tax, service charges, or an automatic gratuity are already included before adding another tip.
If the group rounds each share, compare the rounded group total with the exact bill and handle the displayed difference explicitly.
Preset buttons provide common arithmetic shortcuts, while the custom field accepts zero and percentages above 100%. Presets are not recommendations.
The bill, tip, and total are divided equally by the entered whole number of people. Unequal or itemized splitting is outside this calculator's scope.
By default the entered bill is the tip basis. Pre-tax mode can subtract a known tax amount or derive the subtotal from a tax-inclusive total and entered tax rate. No local rate is assumed.
No rounding is the default. Whole-unit and custom-increment options affect only the displayed per-person payment; the original tip and exact total remain unchanged.
Tipping customs vary by location, service, and circumstance. Choose the percentage appropriate to your situation.
Multiply the tip basis by the tip percentage divided by 100.
Multiply the tip basis by 0.15.
Multiply the tip basis by 0.20.
Add the exact tip to the bill, then divide the total by the number of people.
For an equal split, each person pays the exact total divided by the number of people, subject to any optional displayed rounding.
Divide the exact tip amount by the number of people.
Practices differ. The calculator supports either the full entered bill or an entered or derived pre-tax subtotal without recommending one convention.
Yes. Enter any finite non-negative percentage within the calculator's validation range.
Yes. The tip becomes zero and the total remains the entered bill.
Choose whole-unit upward rounding, nearest-whole rounding, or a custom upward increment.
No. The exact tip remains unchanged; the calculator reports the group rounding adjustment separately.
No. This version splits equally and does not assign items or custom shares to individuals.
