So how does a $100 donation actually land?
Card processing costs real money — that never goes away. What changes is who pays it, and it is never you.

Donor does not cover them
Stripe's fee comes out of the gift. KindLumen still takes nothing.

Many donors choose to cover transaction costs, helping organizations keep more of every donation. Stripe's example rate is 2.9% + 30¢ and goes directly to Stripe. Rates differ for international cards, currency conversion, and non-card payment methods, so coverage is an estimate for those.

Pricing questions, answered.
Is KindLumen really free?
Yes. KindLumen does not charge organizations setup fees, subscription fees, or platform fees.
How does KindLumen make money?
Donors may choose to cover transaction costs. That additional amount covers payment processing and includes a 0.5% contribution that helps operate KindLumen.
What happens if a donor does not cover transaction costs?
The donor pays only their selected donation amount. Stripe’s processing fee is deducted from the donation, and KindLumen receives nothing.
Does the organization receive the full donation?
When the donor covers transaction costs, the organization receives the full donation amount they selected. When the donor does not cover the costs, Stripe’s processing fee is deducted.
Is the donor contribution optional?
Yes. Donors can choose whether to cover transaction costs before completing their donation.
