Frequently Asked Questions
How do I calculate a restaurant tip?
Multiply the bill amount by the tip percentage, then divide by 100. Example: for a $80 bill and 20% tip, tip is $16. Total becomes $96 before any split.
Should tip be calculated before or after tax?
Both methods exist. Many people tip on pre-tax subtotal, while others tip on the final taxed amount. This calculator supports both so you can match your preference or local norm.
How do I split a bill with tip included?
First compute total = bill + tax + tip, then divide by the number of people. You can also split only the tip amount per person for transparency.
Can I reverse-calculate the bill from a known total?
Yes. If you know total paid and tip rate, the calculator can estimate the original bill and implied tip amount using reverse formulas.
