Matching Gift Calculator

This calculator shows how much extra a nonprofit receives when a donor's employer runs a matching-gift program, and how close the donor is to maxing out that benefit. It first checks the donation against the program's minimum eligible gift; below that threshold, no match applies regardless of the ratio. If eligible, the raw match is the donation multiplied by the match ratio (a ratio of 1 means dollar-for-dollar, 2 means the employer doubles it, 0.5 means fifty cents per dollar), then capped at the program's annual per-employee match limit — many corporate programs cap total matches at $1,000-$25,000 per employee per year. Total gift to the nonprofit is simply the donation plus whatever match survives that cap.

The effective multiplier expresses the combined gift as a factor of the original donation, useful for donors comparing employers or programs. Donation-to-max-match works backward from the cap and match ratio to show the smallest donation that would exhaust the full match, and additional-to-max is the gap between that figure and what you actually entered — helpful if you're deciding whether to bump up a gift to capture the full corporate match before year-end. Match utilization shows what fraction of the annual cap this single donation used, which matters for donors who give multiple times a year and need to track remaining headroom. This tool assumes a single donation against a single annual cap; a donor giving to multiple charities under the same employer program needs to track cumulative usage separately.
