Fundraise Up vs Mightycause Comparison 2026
Fundraise Up takes a flat 4 percent of every donation for its platform alone, with Stripe or PayPal processing charged on top of that. Mightycause charges no monthly fee and states an all-in ceiling of never more than 1.99 percent plus 49 cents per donation, covering platform and processing together, with many organisations paying less. On percentage alone Mightycause is the cheaper of the two; the trade is that it only serves United States nonprofits operating as a donor advised fund.

Fundraise Up
A donation checkout tuned to raise more
Fundraise Up replaces a donation form with a checkout tuned to raise the amount given: suggested upgrades, a monthly nudge, wallets and a currency the donor recognises. It charges four percent of what comes in and sells no plans at all. The company's own figure is that most donors elect to cover that cost, which is the argument for a percentage over a subscription.
Our note
Four percent on top of processing is more than a plain Stripe form costs, and the case for it is that the checkout raises more than it takes. Ask for the figures on comparable organisations before assuming that holds for your audience.

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 Fundraise Up
- Mightycause covers the same nonprofit fundraising with no monthly bill.
- Fundraise Up instead of Mightycause
- Fundraise Up focuses entirely on the checkout screen itself, tuned to raise more per donor rather than adding peer-to-peer or event tools.
Which one should you pick
Pick Fundraise Up if you are not a registered US nonprofit, or if the checkout itself, suggested amounts, a recurring-giving nudge, wallets, is worth the extra points to your revenue. Its 4 percent is a platform fee only; card processing is added on top of that.
Pick Mightycause if you are a United States nonprofit and want the lowest all-in rate available here: never more than 1.99 percent plus 49 cents per donation, covering both the platform and card processing, with no monthly bill. It also operates as a donor advised fund, handling receipting and 501(c)(3) paperwork on your behalf, worth understanding before you switch since it changes who technically receives the gift.
Common questions
- Which one actually costs less per donation?
- Mightycause, on the numbers given: its all-in ceiling is 1.99 percent plus 49 cents, covering platform and card processing together. Fundraise Up's 4 percent is the platform fee alone, with Stripe or PayPal processing charged separately on top of it.
- Can any organisation use Mightycause?
- No. Its listing states it is built for United States nonprofits and that anybody outside the United States is in the wrong place. Fundraise Up does not carry that restriction and serves non-profits and creators raising money from a cause more broadly.
- What is a donor advised fund and why does Mightycause use one?
- It is the structure that lets Mightycause handle receipting and 501(c)(3) paperwork on an organisation's behalf, so compliance is not the nonprofit's problem. Fundraise Up carries no equivalent structure in the listing; it is a checkout layered onto an organisation's own donation page.
- Does either platform prompt donors for a tip?
- Fundraise Up offers donors the option to cover its 4 percent fee at checkout, and states most choose to. Mightycause's listing explicitly states there is no tip prompt at all, since its rate is designed to already sit below 1.99 percent plus 49 cents.
