5 Donor Metrics Every Nonprofit Should Track in 2026

Canadian nonprofits are giving to fewer people, and more of them are giving monthly. CanadaHelps' Giving Report 2026 found that donations through its platform reached $529 million in 2025, up 10% year over year, while the share of donors giving monthly has doubled over the past several years to more than 15% of all donors. At the same time, the overall number of Canadians donating has kept declining.

That combination, a shrinking donor base giving more and more often, makes the metrics you track more important than the headline number most boards still ask about first: total dollars raised. Total revenue can rise for a year or two even while your donor base quietly erodes underneath it. The five donor metrics below are the ones that catch that erosion early, and they're the same ones a donor management platform should be tracking for you automatically.

1. Donor Retention Rate

Donor retention rate is the percentage of last year's donors who gave again this year. It's the most-cited metric in nonprofit fundraising, for a simple reason: retaining a donor is far cheaper than replacing one.

Formula: (Donors who gave this year and last year ÷ Total donors last year) × 100

Benchmark: According to the Fundraising Effectiveness Project's Q1 2026 report, drawn from giving data across thousands of organizations and millions of individual donors sector-wide, donor retention for the most recent full year stood at 43.3%. Benchmarks vary by source and organization size (some platform-specific studies report figures anywhere from the low 30s to the mid-50s), so track your own year-over-year trend alongside any external number.

Why it matters: A nonprofit retaining at 30% has to replace 70% of its donor base every single year just to stay flat, an expensive treadmill. Retention tells you whether your relationships are working, not just your reach.

2. Donor Lifetime Value (LTV)

Donor lifetime value estimates the total amount a donor will give over the full span of their relationship with your organization, not just their next gift.

Formula: Average Annual Donation × Average Number of Years as a Donor

Example: A donor giving $150/year who stays engaged for 6 years has an estimated LTV of $900.

Why it matters: LTV turns retention from an abstract percentage into a number your board feels. Blackbaud's donor retention research notes that a 10% improvement in retention rate can translate into roughly a 200% increase in donor lifetime value over time, since donors who stay tend to give more as the relationship deepens, not just more often.

3. Average Gift Size

Average gift size is total donation revenue divided by number of gifts, but it's far more useful broken down by segment (one-time vs. monthly, online vs. offline, new vs. returning) than as a single blended figure.

Benchmark: The 2026 Virtuous Nonprofit Benchmark Report, built on giving data from 771 mid-sized U.S. nonprofits, puts the average nonprofit gift at $136 in 2026 (excluding outlier gifts of $10,000+, which skew the number upward). CanadaHelps' 2026 data shows a similar pattern north of the border: as the number of Canadians donating has declined, average donation amounts have risen, a smaller and more committed donor base giving more per gift.

Why it matters: Growing your average gift from donors who already trust you is usually more cost-effective than chasing new ones. The relationship-building work is already done.

4. Donor Acquisition Cost

Donor acquisition cost is what you spend, on average, to bring in one new donor, including staff time, ad spend, direct mail, and platform fees.

Benchmark: The Fundraising Effectiveness Project estimates it costs 50 to 100% more to acquire a new donor than to secure an additional gift from a donor you already have.

Why it matters: Acquisition is necessary, every nonprofit needs new donors to offset natural attrition and fund growth, but tracking cost-per- acquisition alongside retention rate keeps you honest about where your fundraising budget is actually working hardest. A donor who costs $75 to acquire and gives $50 once is a net loss the moment they don't come back.

5. First-Time Donor Retention Rate

This is the sub-metric most nonprofits skip, and it's often where the real problem is hiding. First-time donor retention, sometimes called second-gift conversion, measures the percentage of brand-new donors who go on to make a second gift.

Benchmark: Research from Keela found that only 14% of first-time donors give a second gift, making the gap between gift one and gift two the sector's single biggest retention leak.

Why it matters: Blending first-time and repeat donors into one overall retention number hides this problem. A nonprofit can post a respectable-looking overall retention rate while still losing the vast majority of everyone new who walks through the door. A fast thank-you and a clear next touchpoint in the first 90 days after a first gift are what most directly move this number.

Tracking All Five Without the Spreadsheet Headache

None of these five metrics is hard to calculate on its own. Keeping all five current, segmented, and visible to your whole team every month, without someone manually pulling numbers from three different systems, is where most nonprofits fall behind.

That's exactly what a donor management platform is for. Infaque tracks donor retention, lifetime value, gift size, acquisition cost, and first-time donor conversion automatically as gifts come in, so your team spends time acting on the numbers instead of assembling them.
