MonthFund vs. Zeffy
MonthFund vs. Zeffy:
Transparent fees vs. donor tips.
Zeffy is a solid general-purpose nonprofit platform. But it does not support pick-a-date calendar fundraisers, and it funds itself through donor tips. MonthFund is the specialist for the calendar model, with honest, disclosed pricing.
No credit card required. Free to start.
Two different models
MonthFund charges a clear, disclosed infrastructure fee on each donation. Donors see exactly what they are paying and can cover it in one click. Your donors give to you, not to our software.
MonthFund is free to launch. We use a transparent infrastructure fee that donors see and cover at checkout, so your cause keeps 100% of their intended gift. Zeffy funds their platform by showing donors a default tip at checkout, often 10 to 15 percent. On a $10,000 campaign, that is up to $1,500 going to Zeffy rather than your cause.
Why organizations choose MonthFund
Built for the calendar fundraiser. Nothing else.
Zeffy does not support calendar fundraisers
Zeffy covers donation forms, events, peer-to-peer, and memberships. It does not offer a pick-a-date or 31-day calendar fundraiser format. If the calendar model is your primary fundraiser, MonthFund is the only purpose-built option.
Your cause keeps 100%. Donors cover the infrastructure.
MonthFund adds a transparent 3% infrastructure fee at checkout. Donors see it, understand where it goes, and cover it in one click. Because it is clear and honest, the vast majority choose to, meaning your organization receives the full intended gift. Zeffy asks donors for a platform tip at checkout instead, typically defaulted at 15 percent.
Tools built for the 31-day format
MonthFund includes individual participant calendar pages, automated fill-rate reminders, live day-by-day tracking, and campaign-over-campaign reporting. All of it is built specifically for the 31-day format. None of it exists in Zeffy.
Predictable take-home for your org
With MonthFund, the math is calculable before you recruit a single participant. A fully funded calendar at 3% is predictable. With Zeffy, your take-home depends on how many donors tip and at what rate. Tip-dependent revenue is not predictable.

Full pricing breakdownExample: $10,000 campaign
No. Zeffy supports donation forms, events, peer-to-peer, memberships, and auctions. It does not offer a pick-a-date or 31-day calendar fundraiser format. MonthFund is built specifically for this model.
Zeffy shows donors an optional tip at checkout, typically defaulted at 10 to 15 percent, which goes to Zeffy rather than your organization. Zeffy reports that about 2 out of 3 donors leave a tip. MonthFund charges a transparent 3% infrastructure fee instead.
No. MonthFund works for any group with a community: schools, PTAs, sports teams, faith communities, civic organizations, and nonprofits. Zeffy is restricted to registered nonprofits. MonthFund is open to all.
Yes. Some organizations use Zeffy for general donation forms and event ticketing, while using MonthFund for their calendar fundraiser. The tools serve different purposes.
The fee is fully disclosed at checkout. Donors choose to cover it. Because it is transparent and clearly explained, the vast majority do, meaning your organization receives 100% of their intended gift. The key difference from Zeffy is that donors know exactly what the fee is and where it goes. There are no default tips or hidden opt-ins.
