Donorbox vs Mightycause Comparison 2026
Donorbox charges 2.95 to 3.95 percent free, or $150 a month for Pro's 1.75 to 2 percent, in exchange for an embeddable form, event ticketing and an API on Pro. Mightycause never charges a monthly fee and caps its combined platform and processing rate at 1.99 percent plus 49 cents, undercutting even Donorbox's discounted Pro plan. Mightycause's low rate comes from operating as a donor advised fund, which hands over 501(c)(3) paperwork and receipting but changes who technically receives the gift.

Donorbox
Donation pages and recurring giving
Donorbox is built for nonprofits and reads that way, which is exactly right for a creator running a fundraiser or a cause and wrong for one collecting tips. Recurring donations, an embeddable form and donor records are the substance. Its free plan charges a higher percentage on each gift than the paid one.
Our note
Pro costs $150 a month and saves roughly 1.5 percent per donation, so it pays for itself somewhere around $10,000 a month in giving. Below that the free plan is the cheaper one, whatever the fee percentage looks like.

Mightycause
Nonprofit fundraising with no monthly bill
Mightycause gives a nonprofit donation pages, peer-to-peer fundraising and event tools without a subscription, and it operates as a donor advised fund, which is what lets it handle receipting and the 501(c)(3) paperwork on the organisation's behalf. The company states an overall ceiling on what a donation costs rather than splitting platform and processing. There are no donor tip prompts. Anybody outside the United States is in the wrong place.
Why people weigh these two
- Mightycause instead of Donorbox
- Mightycause is nonprofit fundraising with no monthly bill, which undercuts paid plans while gift volume is still small.
- Donorbox instead of Mightycause
- Donorbox leans on recurring giving pages rather than the donor advised fund model, suited to an organisation that already handles its own receipting.
Which one should you pick
Pick Donorbox for the features a donor advised fund does not usually offer: an embeddable form for your own site, event ticketing, peer-to-peer campaigns and, on the $150 a month Pro plan, an API and crypto and stock donations. It also does not restrict itself to United States organisations the way Mightycause's own description does.
Pick Mightycause for the lowest combined rate available here, never above 1.99 percent plus 49 cents with no monthly fee at all, beating Donorbox's free plan and its $150 a month Pro tier alike. It suits a small or mid-size United States nonprofit that wants receipting and compliance handled for it and does not want a donor tip prompt on the page. Understand the donor advised fund structure before switching, since it changes who technically receives each gift.
Common questions
- Which one is cheaper?
- Mightycause, at every tier. Its combined rate never exceeds 1.99 percent plus 49 cents with no monthly fee, while Donorbox charges 2.95 to 3.95 percent free or 1.75 to 2 percent plus a $150 a month subscription on Pro.
- Why would a nonprofit pick Donorbox despite the higher fee?
- For features Mightycause does not describe: an embeddable form for your own website, event ticketing, peer-to-peer campaigns, and on Pro, an API plus crypto and stock donations. Donorbox also is not limited to United States organisations the way Mightycause's own page states it is.
- What is a donor advised fund, and why does Mightycause use one?
- It is the structure that lets Mightycause handle 501(c)(3) paperwork and receipting on a nonprofit's behalf, which is part of how it keeps its rate so low and its fee simple. The trade is that it changes who technically receives a gift, worth understanding before moving an existing fundraiser over.
- Does either platform ask donors to add a tip at checkout?
- Mightycause does not; its checkout has no tip prompt at all. Donorbox lets a donor opt to cover the processing fee at checkout instead, which most donors are stated to take, but that is a fee-cover option rather than a separate tip.
