How to use Tip Calculator
Free tip calculator: split a bill and calculate the tip and total per person.
Open Tip Calculator on toolpermarket, then enter the values you want to work with.
In the Bill field, enter the pre-tip total. Use the subtotal before tax for a clean tip base.
In the Tip percent field, enter the gratuity rate, often 15 to 20. Round the result up a little for a smoother total.
Press Calculate to compute the result. The output appears immediately below the form. Tweak any field and run it again to check a different scenario.
Read the result and use it as needed. If the number looks off, re-check your inputs and run it again — the math is deterministic, so the same entries always return the same answer.
Worked example. On a $48 bill, an 18 percent tip is $8.64, making the total about $56.64.

When you actually reach for this
- You are splitting a restaurant bill and want the tip plus per-person share.
- You want to reverse-engineer the tip from a total you already paid.
Where this tool stops being accurate
- It assumes the tip is calculated on the pre-tax subtotal; some regions tip on the post-tax amount, which gives a slightly higher tip.
- It does not cap or round the per-person split, so you may need to settle a cent or two in cash.
Frequently asked questions
Should I tip on the tax or the subtotal?
Custom varies. In much of the US people tip on the pre-tax subtotal, while some tip on the full post-tax total. Neither is wrong; pick the local norm. The tool computes the tip from whatever base you enter, so use the subtotal if that is your habit. For anything binding, check with a qualified professional about your specific situation.
How do I split the tip across a group?
Compute the tip on the whole bill first, add it to the bill for the total, then divide that total by the number of people. The tool gives the per-person share if you enter the split count, or you can divide the final total yourself. For anything binding, check with a qualified professional about your specific situation.
What is a normal tip percentage?
In many service cultures 15 percent is standard, 18 to 20 is common for good service, and 10 or below signals a problem. The rate is a social norm rather than a rule, so match what the situation expects. For anything binding, check with a qualified professional about your specific situation.
Should I tip on the pre-tax or post-tax amount?
In the US the tip is usually calculated on the pre-tax subtotal, but some people tip on the total. The tool lets you enter the base it should use, so pick whichever your group prefers. For anything binding, check with a qualified professional about your specific situation.
