MonthFund vs. 99Pledges

MonthFund vs. 99Pledges:
Calendar model vs. a-thon model.

99Pledges is a solid platform for walk-a-thons, read-a-thons, and other pledge-based fundraisers. MonthFund is built for the 31-day pick-a-date calendar fundraiser. Different mechanics, different results. Here is how they compare.

No credit card required. Free to start.

Two different models

MFCalendar Fundraiser Specialist

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.

9A-Thon Platform with Donor Tips

99Pledges is free for organizers. They fund their platform through optional donor tips, typically defaulted at a percentage of the donation, plus a 3.49 percent processing fee. The a-thon model relies on participants collecting pledges per unit of activity, like laps walked or books read. The calendar model gives each participant a specific day to own and fill with donors.

Why organizations choose MonthFund

Built for the calendar fundraiser. Nothing else.

Two different fundraising models

A-thons are activity-based: participants collect pledges per lap, per book, per mile. Calendar fundraisers are day-based: participants own a specific day and fill it with donors. Both work. The calendar model is more predictable because the math is fixed before the campaign starts.

No donor tips

99Pledges asks donors for a platform tip at checkout. MonthFund charges a clear 3% infrastructure fee that donors can see and choose to cover. Your donors give to your cause, not to our software.

Predictable floor before you start

With the calendar model, you know the minimum outcome before you recruit a single participant. 25 participants, 31 days, $1 per day per donor: the math is visible. A-thon outcomes depend on activity levels that are harder to predict.

Participant ownership drives results

In the calendar model, each participant owns a specific day. That ownership creates accountability. Participants are not just collecting pledges. They are responsible for filling their day. This structure tends to produce higher per-participant results.

Questions

Common questions about switching.

Still deciding? Ask us directly.

An a-thon is activity-based. Participants collect pledges per unit of activity, like laps walked or books read. A calendar fundraiser is day-based. Each participant owns a specific day on a 31-day calendar and fills it with donors who give an amount equal to that day number. The calendar model is more predictable because the math is fixed before the campaign starts.
