Ways to use the Percent Memory

The percent memory can be used for applying sales or VAT tax, determining a standard tip, or even applying a discount. We'll show examples of each situation.

Sales Tax

Let's say your local tax rate is 9.25% (a typical rate in California). Set the tax rate by entering 9.25 and pressing %in to save it into the percent memory. Now each time you need to figure this tax, simple enter the one value and press +%.

Example: for $300 item, enter 300 and press +% to get a result of 327.75.

Tip Calculation

We customarily tip on restaurant bills 15%. We can save this value in the percent memory by entering 15 and pressing %in.

Example: For a $22.20 bill, we enter 22.50 and press +% for a result of 25.53.

If we needed to split the bill 3 ways, just divide the result by 3, for a final result of $8.51 per person.


We can make quick work of a sale or discount by entering a negative number into the percent memory. We have a garage sale and want to discount everything by 33% during the last hour of the sale. Type -33 and press %in to save this discount rate.

Example: An item is prices at $200, so enter 200 and press +% for a result of 134.
