About Tip Calculator
The Tip Calculator is a free online tool that works out the tip you should add to any bill. Enter the bill amount and the tip percentage, and it instantly returns the tip in dollars and the full total you would pay.
Use it before you pay at a restaurant, salon, or taxi, or whenever you want to check the arithmetic on a suggested tip. Because it accepts any bill amount and any percentage, it also works for custom gratuities on deliveries, hotel stays, and other services.
The math runs entirely in your browser, so your numbers stay private and results appear the moment you press Calculate.
Formula & Mathematical Calculation
Tip Amount = Bill Amount × Tip % ÷ 100
Total = Bill Amount + Tip Amount
Where: Bill Amount = your pre-tip bill in dollars, Tip % = the gratuity percentage you choose.
Calculation Example
For a bill of $50 with a tip of 18%, the tip amount is $9 and the total you pay is $59. The tool multiplies the bill by the percentage to get the tip, then adds it back to the bill for the total. Enter your own bill amount and tip percentage to see both figures instantly.

Assumptions & Limitations
What the calculation assumes

- Rates and contributions are assumed to stay constant for the whole period unless the form asks for them separately.
- Results use standard financial formulas and ignore fees, penalties and promotional terms that are not entered above.
- Inflation, tax changes and market volatility are not modelled unless a field for them is provided.
- Amounts are unit-agnostic: results are returned in the same currency you enter.
What it does not cover
- Tip Calculator produces estimates for education and planning, not a quote, offer or professional advice.
- Real-world outcomes differ when fees, taxes, rounding rules or provider-specific terms apply.
- Local regulations and tax rules vary by country and change over time; verify current rules for your jurisdiction.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For decisions with lasting financial impact, confirm the numbers with a qualified professional.
