Tip Calculator
Calculate a tip, tax, included gratuity or service charge, bill split, and rounded payment. The calculator remains visually structured in both dark and light themes while the supporting cluster links guide users to deeper answers.
Calculate your tip and total
Essential fields stay visible. Tax, included charges, location, currency, tip base, and rounding remain inside one aligned advanced-options block.
How the calculation works
A concise explanation belongs on the tool pillar; the complete tutorial is linked into the supporting guide cluster.
Core formula
For a $50 pre-tax subtotal at 20%, the tip is $10. If tax, fees, or an included gratuity are present, the calculator shows each amount separately.
Receipt check
Look for gratuity, service charge, service fee, or similar wording before adding another tip. An included gratuity can count toward your target; an unclear compulsory fee should remain separate until the venue explains it.

Frequently asked questions
How do I calculate a tip?
Multiply the selected tip base by the percentage divided by 100. A 20% tip on a $50 subtotal is $10.
Should I tip before or after tax?
A pre-tax tip uses the subtotal. A post-tax tip uses the subtotal plus tax. The calculator keeps this choice explicit so you can match your intention.
What if gratuity is already included?
Enter the included charge and identify it as gratuity. The calculator counts it toward your target and adds only any positive difference.
Is a service charge the same as a tip?
Not necessarily. A compulsory service fee may be distributed differently. The calculator can add it to the total without assuming it replaced a voluntary tip.
How do I split a bill fairly?
Equal splitting is suitable when orders are similar. Use the itemized Split Bill Calculator when individual orders or shared items differ.
Why can the effective percentage change after rounding?
Rounding the tip, total, or each person’s payment changes the final gratuity. The calculator reports the effective percentage after that adjustment.
Methodology
- Percentage tips use the selected pre-tax or post-tax base.
- Included gratuity reduces only the additional tip needed.
- Service charges are added without automatically counting as voluntary gratuity.
- Rounding is applied after the initial calculation.
- Currency changes formatting; it does not perform exchange-rate conversion.
- The comparison chart uses semantic HTML and CSS; no third-party chart or screenshot library is used.
