How to use the round-up tip calculator
Enter bill amount, minimum tip (%), and round total to multiple of. Choose the currency for your inputs and read the result as you change the values.
How it works and formula
Find the bill plus the minimum tip, then round up to the next selected multiple. The difference from the bill is the tip.
Worked example
| Bill amount | 80 |
|---|---|
| Minimum tip (%) | 18 |
| Round total to multiple of | 5 |
Result
Pay $95.00 · Tip $15.00
Try a second calculation
Start with the USD worked example above and change only round total to multiple of to 10. Select Calculate. Your result should read:
Pay $100.00 · Tip $20.00
Then enter 1 in the same field. Compare the result with the first scenario row. Holding every other input steady lets you see exactly how this one change affects the calculation.
Choosing your inputs
Choose your minimum tip first, then decide what kind of total you want to see on the receipt. A multiple of one rounds up to a whole currency unit. A multiple of five may increase the payment further. Use the smaller multiple if the exact percentage matters more to you.
How to interpret the result
Read the final payment and the tip separately. The minimum percentage is a starting point. The extra amount needed to reach your chosen multiple becomes part of the tip, so the effective percentage may be higher, especially on a small bill.
