How it is calculated
Multiply the entered percentage as a decimal by the base amount: result = percentage / 100 × base. This answers “what is X percent of Y,” not percentage change.
Assumptions
The rate applies to the stated base; taxes, fees, and store rules are not known automatically.
Example
Entering 20% and a base of 100 gives 20. To calculate an increase between two values, use Percentage Change Calculator instead.
Limitations
Check the receipt, local taxes, fees, minimums, and rounding before paying.
