What it does

Employer matches double careful gifts when ratios and caps line up. Two hundred fifty dollars at dollar for dollar with a $1,000 cap draws $250 for $500 of impact with $750 of cap left.

The tool above takes the donation, match ratio, and yearly cap. It returns matched dollars, total impact, and cap left, so year end gifts can be timed before caps reset.

This math fits flat ratios with one cap. It does not fit tiered ratios that drop after thresholds, minimum gift floors, or ineligible gifts outside program rules.

Charity guidance frames the same split: exempt status and contribution rules decide deductibility, while transparency data helps donors check recipients. Match forms then move the employer dollars.

File the match form with the gift receipt. Unfiled matches are the most common lost dollars in workplace giving.

How to use

  1. Enter your donation dollars.
  2. Enter match ratio, 1 for dollar for dollar.
  3. Enter yearly match cap remaining or total.
  4. Read matched first for employer dollars.
  5. Read total impact for the charity line.
  6. Read cap left to plan the next gift.

Formula

Matched = min(donation x ratio, cap). Total = donation + matched. Left = cap - matched.
donation
Your gift dollars submitted for match.
ratio
Employer dollars per your dollar.
cap
Yearly employer match ceiling.

Zero ratio or zero donation gives zero matched. Caps bind large gifts first. Minimums and eligibility sit outside this ratio math.

Worked example

Example: $250 gift at 1 to 1 with $1,000 cap

Donation 250, ratio 1, cap 1000.

  1. Raw match: 250 x 1 = $250.00.
  2. Capped: smaller of 250 and 1000 is $250.00.
  3. Total: 250 + 250 = $500.00.
  4. Left: 1000 - 250 = $750.00.
  5. Tool shows matched $250.00, total $500.00, cap left $750.00.

Limits

  • Flat ratio only. Tiers need split lines.
  • Ignores minimum gift floors for eligibility.
  • Ignores ineligible gifts outside program rules.
  • Tax deductibility follows charity and gift rules.

Common mistakes

  • Assuming every gift matches without filing forms.
  • Missing the yearly cap on large gifts.
  • Entering ratio as percent instead of to 1.
  • Counting pledged matches as received dollars.
  • Skipping recipient eligibility checks.

Questions

How do matching gifts work?

Employers add ratio dollars per your dollar up to a cap. $250 at 1 to 1 draws $250.

What does the cap do?

It bounds yearly matches. Gifts past the cap draw no more employer dollars.

What is total impact?

Your gift plus matched dollars. $250 with $250 matched is $500 to charity.

Do all gifts match?

No. Minimums, recipient eligibility, and deadlines filter which gifts qualify.

How do I claim a match?

File the employer form with the charity receipt, usually online within months.

Is matched money deductible to me?

Generally only your gift may deduct under charity rules, not the employer share.
