Start with
the right question.

Use the discount calculator for sale prices, stacked offers, sales tax and working back to an original price. The tip calculator handles pre-tax tipping, rounding and an exact per-person split. The percentage calculator covers any other percentage, change or reverse percentage.

WORKED EXAMPLE

25% off followed by an extra 10% off is 32.5% off in total, not 35%. An $86.40 bill with an 18% tip split three ways is $101.95: two people pay $33.98 and one pays $33.99.
