Key takeaways
- Upgrading a donor means moving them up the value ladder, and it rarely happens on its own: only about 0.5% of donors climb from lower-dollar to mid-level giving in a year (NonProfitPRO).
- The ask string, the set of suggested amounts on a form or letter, is the most direct upgrade tool, because a donor rarely gives more than the highest number you invite.
- A common practice is to anchor suggested amounts on a donor's own giving and step them up, for example 1x, 1.5x, and 2x their average gift for lower and mid-level donors (Bloomerang).
- Timing matters more than nerve: ask for more after a donor has shown commitment through repeat gifts, not on the first touch.
- Donor Insights reads your own giving records to show who is ready to move up and who is slipping, while your team sets the asks in its own tools.
Upgrading a donor means moving them up the value ladder, from a first small gift toward a larger and more committed one, and it rarely happens by accident. Only about 0.5% of donors climb from lower-dollar to mid-level giving in a year on their own, according to NonProfitPRO, which means almost every upgrade is one you deliberately invite. The most direct tool for that invitation is the ask string: the set of suggested amounts a donor sees on a form or in a letter. A donor rarely gives more than the highest number you put in front of them.
What is a donor upgrade?
A donor upgrade is any move to a higher level of giving: a larger one-time gift, a step up in a recurring amount, or the jump from occasional gifts into a monthly commitment. Picture the file as a ladder, with a wide base of small and first-time donors and a narrow top of major donors. Upgrading is the deliberate work of helping donors climb it, one rung at a time, rather than waiting for them to climb on their own, which the data says they mostly will not.
The climb is also worth defending from below. Repeat giving is what carries a donor up the ladder, and the donors most ready to upgrade are usually the ones already giving more than once, which is why a strong mid-level donor program and an upgrade strategy are really the same work seen from two angles.
When should you ask a donor for more?
After a donor has shown commitment, not before. A first-time donor is a near-stranger, and asking them to double their gift the week after they gave asks for trust that is not there yet. The upgrade moment comes once a donor has given again, because the second gift is the signal that a one-time act has become a relationship. Our guide to the second gift covers why that gift is the hinge; the upgrade ask is what you build on top of it.
Calibrate the size of the ask to where the donor already is. Across the sector a typical one-time online donor gave 1.3 times in 2025 for about $183 across the year, according to M+R Benchmarks 2026. Numbers like these are a starting reference, not a target to paste onto every donor: the useful ask is anchored on each donor's own history, stepped up from what they have actually given.
How are ask strings built?
An ask string, sometimes called an ask array, is the row of suggested amounts on a donation form. The common practice is to anchor those amounts on the donor's own giving, usually their average, most recent, or highest previous gift, and step them upward from there, with an open field for anyone who wants to give a different amount. Bloomerang suggests setting amounts at multiples of a donor's average gift:
| Donor level | Suggested amounts, as a multiple of average gift |
|---|---|
| Lower and mid-level donors | 1x, 1.5x, 2x, plus an open field |
| Higher-level donors | 1.5x to 1.75x, 2x to 2.25x, 2.25x to 3x, plus an open field |
Two details do a lot of the work. Keep the string short, roughly three to five choices, so a donor has room to move up without feeling flooded with options. And order the amounts low to high: one test found that arranging the choices high to low instead produced a 25.2% decrease in revenue, because a descending row anchors the donor on the smallest number rather than inviting them upward.
What actually moves a gift higher?
Two things beyond the numbers themselves: a reason and a reference point. The reason is impact, showing what the last gift did before inviting the next. The reference point is what other donors give. In a well-known field experiment by Jen Shang and Rachel Croson, cited by Bloomerang, telling renewing members that another donor had given $300 raised their own gifts by an average of 29%. A credible, specific reference point moves people up more than a bare request does.
The cost of not asking is the quiet drift the other way. About 40% of mid-level donors fall back to lower-dollar giving each year, according to NonProfitPRO, and a donor who is never invited to hold or raise their gift is a donor drifting down by default. An upgrade strategy is as much about arresting that slide as it is about the occasional big jump.
“Increasing customer retention rates by 5% increases profits by 25% to 95%.”
Donors are not customers, and the parallel is imperfect, but the direction holds. A donor who gives more and stays is worth far more over time than one big gift, which is why upgrades are best read through donor lifetime value rather than the size of any single ask.
A worked example: an ask string on a real donor
Picture a fictional donor, Maria, who has given three gifts averaging $40. Anchoring on her average and stepping up gives a short, ascending string built for her rather than for everyone. The numbers below are illustrative.
| Suggested amount | How it is derived |
|---|---|
| $40 | 1x her average gift |
| $60 | 1.5x her average gift |
| $80 | 2x her average gift |
| Other | an open field for any amount |
The row never shows Maria a number below what she usually gives, and the top choice invites her upward without a jump so large it feels unreachable. Do this across a file, anchored on each donor's real history, and small upgrades compound into a meaningfully larger base over a year. Knowing each donor's giving pattern well enough to set the anchor is what RFM segmentation makes possible.
Donor Insights reads your own giving records to show who has given enough to be ready for an upgrade ask and who is drifting down toward a smaller gift, so the invitation lands on the right donor at the right time. The platform surfaces the segment; your team sets the ask strings in its own forms and letters. The methodology behind those readings starts from your file, not a sector average.
Frequently asked questions
- What is a donor upgrade?
- It is any move to a higher level of giving: a larger one-time gift, a higher recurring amount, or the jump from occasional gifts into monthly giving. Upgrades rarely happen on their own, since only about 0.5% of donors climb from lower-dollar to mid-level giving in a year without a deliberate invitation (NonProfitPRO).
- What is an ask string?
- An ask string, or ask array, is the row of suggested amounts a donor sees on a donation form or in a letter. The common practice is to anchor the amounts on the donor's own giving and step them upward, with an open field for any other amount. A donor rarely gives more than the highest number you suggest.
- How should ask amounts be ordered?
- Low to high. One test found that ordering the choices high to low instead produced a 25.2% decrease in revenue, because a descending row anchors the donor on the smallest amount (Bloomerang). Keep the string short, about three to five choices, so the donor has room to move up without feeling flooded.
- When should we ask a donor to give more?
- After they have shown commitment, usually once they have given again. Asking a first-time donor to double their gift asks for trust that is not there yet. The second gift is the signal that a one-time act has become a relationship, and the upgrade ask builds on top of it.
