How to Ask a One-Time Donor to Become a Monthly Donor

You have a donor who gives $100 every spring and sometimes $50 at year-end. You like them. They like you. And every year you hold your breath a little, wondering whether this is the year they forget.

Asking that donor to give monthly is one of the most useful things a small nonprofit can do. Here's the direct answer to how: ask after their second gift or right after you've sent them a progress update, start with donors who already give more than once a year, and frame the monthly amount as a small, concrete unit of progress. Don't ask in the first thank-you, and don't make it feel like a downgrade from their usual gift.

Why does a monthly gift matter so much?

A monthly gift turns an annual decision into an ongoing relationship. The donor decides once, and the giving keeps happening until they decide otherwise.

The retention numbers show why that matters. M+R Benchmarks found that 71% of monthly sustainers were still active after 12 months in 2025. Compare that with one-time donors: the Fundraising Effectiveness Project found donors who gave once in a year came back 31.9% of the time, while donors who gave seven or more times came back 87.4% of the time.

Frequency is loyalty. Every gift is another moment in the donor's giving journey where they're reminded why they care. A monthly gift builds that frequency in by default.

When should you ask a donor to give monthly?

The best moments are right after a second gift or right after a progress update. At both points the donor has just been reminded that their giving does something.

Avoid these moments:

• The first thank-you. A new donor is still deciding whether you're worth a second gift. Asking for twelve gifts in the same breath as your thanks undercuts the thanks. (Here's how to get that second gift first.)
• Right after a big appeal. They just gave. Let them enjoy it.
• When you haven't told them anything recently. If the last thing they heard from you was an ask, a monthly ask is just another ask.

A good rhythm for a one-time donor looks like this:

Moment	What they hear
Gift arrives	A personal thank-you, no ask
A few weeks later	A progress update about what their gift did
Next gift arrives	Thank-you, then a separate note a week or two later inviting them to go monthly
No second gift yet	Another progress update; save the monthly ask

Which donors should you ask first?

Not every donor is a good monthly prospect right now. Start with the ones who've already shown the habit:

1. Donors who give two or more times a year. They're already giving often. Monthly giving is just a more convenient version of what they do.
2. Donors who've given three or more years in a row. They've proven loyalty; a monthly gift protects it from a busy year.
3. Donors who respond to progress updates. If they reply, click, or comment when you share what happened, they care about the ongoing work, which is exactly what monthly giving funds.
4. Recent second-time donors. The second gift is a decision. They're open to deepening it.

A smaller, targeted ask to twenty of these donors usually does better than a blanket "become a monthly donor" line in your newsletter.

How do you frame the monthly amount?

Tie the amount to a unit of progress, not to their annual gift. "$15 a month keeps one student in weekly tutoring" is easier to say yes to than "would you consider $8.33 a month?"

A few principles:

• Make it concrete. One meal, one hour, one night of shelter, one month of a program.
• Keep it modest. For a donor who gives $100 a year, $10 or $15 a month is a meaningful step up without feeling heavy.
• Name what it adds up to. "Over a year, that's a full semester of tutoring for one student."
• Make the monthly progress visible. Promise, and then deliver, short updates on what monthly donors make possible.

Choosing these units is easier if you've already set up a simple program. See how to start a monthly giving program for building the basics.

What should the ask say? A sample email

Here's an email you can adapt. It's personal, it starts with progress, and it asks for one clear thing.

Subject: What your gifts have added up to

Hi Laura,

You've given to our tutoring program twice this year, and I wanted to show you where that went. This fall we're working with 34 students, and 28 of them have moved up at least one reading level since September.

I have a small ask. A handful of our most loyal supporters give monthly, which lets us plan the year instead of hoping. $15 a month covers one student's weekly sessions. If that feels right, you can set it up here: [link]. If not, I'm just glad you're part of this.

Thank you, Marcus

Notice what it does: progress first, a one-sentence reason monthly giving helps the organization, one concrete amount, one link, and an easy out.

A short phone script

A call works especially well for long-time donors. Keep it under two minutes:

"Hi Laura, it's Marcus from the reading program. Nothing urgent. I just wanted to thank you for your gifts this year and tell you that 28 of our students moved up a reading level this fall.

I'm also calling a few of our most loyal supporters to ask if they'd consider giving monthly. Fifteen dollars a month covers one student's weekly tutoring, and it helps us plan ahead. Would you be open to that?

[If yes:] Wonderful. I'll send you a link today. [If unsure or no:] Totally understood. Thank you for everything you already do."

If you reach voicemail, leave the thanks and the progress, skip the ask, and follow up by email.

What do you do when a donor says no?

Say thank you and mean it. A "no" to monthly giving is not a "no" to your organization.

Then:

• Keep sending progress updates. Don't let the monthly ask become the last thing they heard from you.
• Wait at least six months before asking again, and only after another gift or another update.
• Never penalize the annual gift. Thank their next one-time gift as warmly as ever. Use the same thank-you habits you use for every donor.

Some donors will never give monthly. They prefer one meaningful gift a year, and that's a perfectly good relationship.

What happens after someone says yes?

The yes is the start, not the finish. New monthly donors need a warm welcome within a couple of days, a clear sense of what a month of their giving does, and occasional progress notes that show it.

Watch for one quiet risk: failed payments. Cards expire and get replaced, and a monthly donor whose card fails often didn't mean to stop. Have a simple plan for what to do when a monthly donor's card fails before you need it.

Where Perennial fits

Perennial Giving flags donors who are good monthly prospects, like people who just made their second gift of the year, and drafts the ask in your voice using your own recent progress updates. It also notices when a monthly donor's card fails and drafts the gentle follow-up. You approve every message. A sorted spreadsheet and a calendar reminder can do the same job; what matters is asking the right donors at the right moment.

A small ask, at the right time

Asking a donor to give monthly doesn't need a campaign. It needs good timing and a concrete reason. Wait for the second gift or a fresh progress update. Start with donors who already give often. Make the amount feel like progress. And if they say no, keep showing them what their giving does. Many of them will come around on their own.
