Effective January 1, 2021, the optional IRS standard mileage rates for use of a car, van, pickup, or panel truck are as follows:

56¢ (a decrease of 1.5¢ from 2020)Per mile for business use
16¢ (a decrease of 1¢ from 2020)Per mile – for medical or moving purposes
14¢ (no change from 2020)Per mile – in service of charitable organizations

The standard mileage rates for charitable organizations remained unchanged from 2020, with a 1 cent decrease per mile for medical or moving purposes and a 1.5 cent decrease per mile for business use.  The difference between the optional standard mileage rate for business use versus medical or moving purposes is that, while the medical and moving rate takes into account variable costs, the business rate is calculated from an annual study of fixed and variable costs.
