What Are the Giving Day Platforms With the Most Transparent Pricing?

Giving days can be transformational fundraising moments — but only if you’re not blindsided by fees after the fact. Between platform fees, payment processing fees, monthly subscriptions, and add-ons, the “true cost” of a giving day platform is rarely what the headline rate suggests.

This post breaks down five giving day platforms by how transparent — and how affordable — their actual pricing is. We’ll go beyond the advertised rate to show you what nonprofits actually pay per dollar raised.

The 5 Most Transparent Giving Day Platforms, Ranked

1. Mightycause

How Does Mightycause’s Pricing Compare for Giving Days?

Monthly cost: $0

Platform fee: Capped at 1.99% + $0.49 per transaction (all-in)

Processing fee: Included in the all-in rate above

Donor-covers-fees option: Yes — donors are asked to cover an optional 7.9% + $0.30 at checkout

Mightycause leads on pricing transparency — and it’s not close. There’s no monthly subscription, no per-seat charge, and no paywalled features. Per Mightycause’s official fee documentation, the platform fee is capped at 1.99% + $0.49 per transaction, which already includes payment processing. You’ll never pay more than that.

The donor-covers-fees option is a genuine differentiator. When enabled, donors are asked to cover an optional fee at checkout — covering all platform and processing costs. If a donor opts in, the nonprofit receives 100% of the donation. Mightycause’s pricing guarantee also credits back any aggregate fees above 1.99% + $0.49 per transaction before disbursement, so you’re protected even when donors don’t cover

For giving days specifically, Mightycause offers fully branded event microsites, real-time leaderboards, peer-to-peer fundraising, dedicated project management support, and nonprofit training webinars — all included in the platform’s $0/month model. Learn more about how Mightycause powers giving day events.

The bottom line: What you see is what you pay. The fee cap is published, the guarantee is in writing, and the donor-covers-fees model means most organizations keep the full value of every gift.

2. Zeffy

What Is Zeffy’s Pricing for Giving Days?

Monthly cost: $0

Platform fee: 0%

Processing fee: Covered by Zeffy

Donor-covers-fees model: Optional tip to Zeffy at checkout (see Zeffy’s fee model explained)

Zeffy is a legitimate zero-fee platform for nonprofits. It charges no platform fees and covers all payment processing costs. The way Zeffy sustains its model is by presenting donors with an optional tip at checkout — donors can contribute to Zeffy’s operations, but it’s not required, and 100% of the donation still reaches your nonprofit regardless.

That model works well for general fundraising. The caveat for giving days is that Zeffy is not purpose-built for large-scale, community-wide giving events the way Mightycause is. It lacks dedicated giving day infrastructure like branded event microsites, real-time leaderboards across participating nonprofits, giving day-specific project management support, and matching gift prize management. It’s a strong fit for smaller or mid-sized nonprofits that want $0 in fees on standard campaigns — less so for community foundations or universities running a coordinated giving day with dozens of participating organizations.

The bottom line: Genuinely free, and transparent about how it stays that way. Best for general fundraising; limited giving day infrastructure.

3. Donorbox

What Is Donorbox’s Pricing for Giving Days?

Monthly cost: $0 (Standard) / $150/month (Pro) / Contact for Premium (Donorbox pricing)

Platform fee: 2.95%–3.95% (Standard) / 1.75%–2% (Pro) / 1.6%–2% (Premium)

Processing fee (Stripe nonprofit rate): 2.2% + $0.30 — charged separately from platform fee

Combined effective rate (Standard + Stripe): ~5.15%+ per transaction

Donor-covers-fees option: Yes

Here’s where things get tricky. Donorbox’s Standard plan advertises a “free” entry point — but the platform fee and the payment processing fee are charged separately. On the Standard plan using Stripe’s nonprofit rate (2.2% + $0.30), you’re looking at a combined 5.15%+ per transaction before any donor fee coverage kicks in.

The donor-covers-fees checkbox is available, and Donorbox notes that most donors opt in — which helps close the gap. But the fee structure is more complex than a single all-in rate, and that complexity makes apples-to-apples comparisons harder. Popular add-ons like Text-to-Give ($19–$50/month) and Live Kiosk ($80/month for the first device) can also raise the effective monthly cost considerably, even on the “free” Standard plan.

The bottom line: The advertised rate is only half the story. Stack the platform fee and processing fee together before comparing to other platforms.

4. Funraise

What Is Funraise’s Pricing for Giving Days?

Monthly cost: $0 (Essentials) / Starting at $99/month (Premium plans, billed annually) (Funraise pricing)

Platform fee: 5% (Essentials) / 0%–5% depending on Premium plan

Processing fee: 2.9% + $0.60 per card transaction (via Stripe/Funraise Payments)

Combined effective rate (Essentials): ~7.9% + $0.60 before donor fee coverage

Average effective rate with donor coverage: ~2.5% (Essentials) / ~0.8% (Premium plans)

Donor-covers-fees option: Yes (~90% of donors opt in, per Funraise’s pricing page)

Funraise is a capable, well-designed platform with solid event tools, peer-to-peer fundraising, and a clean donor CRM. On paper, the $0 Essentials plan looks competitive. In practice, the 5% platform fee plus 2.9% + $0.60 processing fee means the gross fee burden before donor coverage is close to 8% per transaction — one of the higher rates on this list.

Funraise points to its donor fee coverage rate (~90%) as the offset, and it’s a fair point: if the majority of your donors opt in, your average effective rate drops to approximately 2.5% on the free plan and 0.8% on Premium. That said, the 5% platform fee is a real exposure on any transaction where donors don’t cover — and on a high-volume giving day, that adds up. Notably, peer-to-peer fundraising is locked behind the paid Premium tier, which is a meaningful limitation for giving day-style events.

The bottom line: Strong platform with published fee documentation. The Essentials fee rate is higher than competitors — model the full per-transaction cost before committing to this plan for a giving day.

5. OneCause

What Is OneCause’s Pricing for Giving Days?

Monthly cost: Not published for most plans (requires demo) (OneCause plans overview)

Pay-As-You-Go option: 5% fee on funds raised, starting at $200 (capped — amount disclosed upon request)

Annual subscription: Starts at $2,995/year (Professional Auction and Event package)

Processing fee: Not publicly disclosed

Donor-covers-fees option: Yes (“Cover Costs” feature)

OneCause is a well-regarded platform with deep event fundraising features — auctions, live events, peer-to-peer, and Text2Give. But from a pricing transparency standpoint, it’s the least open on this list. Per OneCause’s plans page, only the Pay-As-You-Go option and the $2,995/year Professional package are publicly disclosed. Subscription pricing for higher-tier plans requires a sales conversation, and payment processing rates are not listed publicly.

The Pay-As-You-Go plan is the most accessible option: a 5% fee on funds raised, with a cap that OneCause will share upon request. For organizations that raise $50,000 or more annually, OneCause recommends moving to a flat annual subscription — but the cost of most subscription tiers isn’t on the pricing page.

OneCause is a strong choice for large events and multi-affiliate organizations with established sales relationships. But if pricing transparency is a priority going into a giving day, expect to spend time in sales conversations before you know what you’ll actually pay

The bottom line: Powerful platform, opaque pricing. Best for established organizations comfortable with a sales-led buying process.

Why Does Transparent Pricing Matter for Giving Days?

Giving days are high-stakes, high-volume fundraising events. A surprise fee structure at the end of the day doesn’t just hurt your bottom line — it erodes trust with participating nonprofits and your donors. Choosing a platform that publishes its full pricing upfront lets you plan accurately, set realistic goals, and communicate honestly with participants.

Mightycause was built with that transparency in mind. Its pricing guarantee, all-in rate cap, and donor-covers-fees model are designed so nonprofits know exactly what they’ll keep before the first donation is processed.

Frequently Asked Questions

What’s the difference between a platform fee and a payment processing fee?

A platform fee is what the fundraising software charges for use of its tools and infrastructure. A payment processing fee is what the underlying payment processor (like Stripe or PayPal) charges to move money. Some platforms — like Mightycause — bundle both into a single all-in rate capped at 1.99% + $0.49 per transaction. Others, like Donorbox and Funraise, charge them separately, which can make the true cost significantly higher than the advertised platform fee alone.

How does the donor-covers-fees model actually work?

When a nonprofit enables this option, donors see a checkbox or prompt at checkout offering to add a small amount to their donation to cover processing costs. If the donor opts in, the nonprofit receives 100% of their intended gift. Mightycause’s pricing guarantee goes a step further: it credits back any aggregate fees above 1.99% + $0.49 per transaction before disbursement, so the nonprofit is protected even if some donors don’t cover. See Mightycause’s fee documentation for full terms.

Is a $0/month platform always the best deal for a giving day?

Not necessarily. A $0 monthly fee is a great starting point, but the real question is what you’re paying per transaction. A platform with no monthly fee but a 5% platform fee plus a 2.9% + $0.60 processing fee is considerably more expensive than one with a capped all-in rate of 1.99% + $0.49. For a giving day that raises $100,000, that difference could be $3,000–$7,000 in fees. Always model the full per-transaction cost before choosing a platform for a high-volume event.
