Choose the Tip Base and Percentage
Enter the amount you want to use as the tip base and the percentage you choose. The calculator does not assume whether you should tip on a pre-tax or after-tax amount; use the amount that matches your situation.
The split divides both the total and tip evenly across the number of people entered. Tipping customs vary by country, service type and situation, so the preset buttons are conveniences rather than quality ratings or recommendations.
A tip calculator only handles the arithmetic. Tipping customs vary by country, type of service, venue and sometimes by whether a service charge is already included. If you are splitting the bill evenly, the calculator can divide the bill and tip across the group; if people ordered very different amounts, an equal split may not reflect what the group actually wants to pay. Check the receipt for included gratuity before adding another tip.
Frequently Asked Questions
Can I enter a 0% tip?
Yes. A zero tip is a valid mathematical input and leaves the total equal to the entered amount.
Does RatioCalc say what tip percentage is appropriate?
No. Tipping norms vary by place and situation. The calculator only applies the percentage you choose.
Should I tip on the pre-tax or after-tax amount?
There is no universal rule. Customs vary, and some receipts or payment terminals calculate suggested tips from different bases. Enter the amount you actually want to use as the tipping base.
