A donation form asks for something rare: money given with nothing tangible in return. That makes every detail matter. A confusing form or a flat, transactional feel can turn a willing giver into a closed tab.
The good news is that small, honest design choices — suggested amounts, a clear why, a warm confirmation — reliably lift what an average visitor gives.
Suggest amounts, do not just ask for one
A blank amount box forces a decision most people do not want to make, so they either give the smallest round number or hesitate and leave. Offer a few suggested amounts and you anchor the choice — and gently raise it.
- Show three or four preset amounts, plus a custom option.
- Tie amounts to real impact where you honestly can.
- Keep a low entry point so nobody feels shut out.
Offer to make it monthly
A one-time gift is generous; a recurring one is transformative for a cause. Simply offering a monthly option next to the one-time one converts a meaningful share of givers into regular supporters, and the lifetime value dwarfs the single gift.
Make it a clear, optional toggle — never a default that surprises someone on their statement.
Say what the money does
People give to outcomes, not to organisations. One concrete line about what a gift makes possible does more than a mission statement. Show the effect, not the org chart.
- Connect the amount to a specific, believable result.
- Keep the copy short — this is a form, not a brochure.
- Reassure that the payment is secure without a wall of text.
Make the thank-you feel like gratitude
The moment after giving is when a donor decides whether they will give again. A warm, specific thank-you — and a receipt — turns a transaction into a relationship. A generic confirmation wastes the best moment you will get.
You can build a donation form with suggested amounts and a recurring option, free, at onesol.io/forms.
Choose Your Suggested Amounts on Purpose
The preset amount buttons are the single most powerful control on a donation form, and most are set carelessly. Offer three or four options, and let the middle one carry the weight — people anchor to it and drift towards the centre, so if your buttons read £10, £25, £50 and £100, the £25 and £50 do most of the lifting. Set them too low and you cap generosity; set them all too high and you scare people into the open field or away entirely.
Give each amount a meaning where you honestly can, because a number tied to an outcome outperforms a bare figure. "£25 stocks a family's food parcel for a week" gives the donor a picture of what their money becomes, and a picture is far more persuasive than a price. Keep the descriptions short and true — inflated claims read as sales patter and quietly erode trust.
Always keep an open "other amount" box alongside the presets, but don't lead with it. An empty field asks the donor to invent a number from nothing, which is work, and work at the moment of giving costs you gifts. The presets do the thinking; the open field catches the person who already knows they want to give £37.
Make Monthly Giving the Obvious Option
A recurring supporter is worth many times a one-off donor, yet most forms bury the monthly option or omit it. Put a clear one-time / monthly toggle at the top, and frame the recurring gift by its monthly cost, not its annual total. "£5 a month" feels smaller and more doable than "£60 a year", even though it is more — the per-month framing is what makes the ask land.
Be honest in how you present it rather than clever. Showing the monthly option prominently is fair; pre-ticking recurring so someone signs up for it without noticing is the kind of dark pattern that produces chargebacks, angry emails and cancelled memberships. Let the donor choose, make the better-for-you choice easy to see, and let the framing — not a hidden default — do the persuading.
Once someone gives monthly, the confirmation is your chance to cement it: tell them exactly what the date and amount will be, and how to change or stop it in one click. Donors who know they are in control cancel less, because the anxiety that drives cancellations is usually "how do I get out of this", not the money itself.
Small Frictions Removed, Small Amounts Recovered
Payment processing quietly eats a slice of every gift, and there is a graceful way to recover most of it: a small opt-in checkbox that lets the donor add the fee so the full amount reaches you. Worded plainly — "Add £0.95 to cover processing so we receive your whole £25" — a surprising share of people tick it, because they would rather the cause got the full sum than the payment provider.
The rest is about removing hesitation at the exact moment of giving. Don't force account creation to donate; a guest gift that takes ten seconds will always beat a signup wall. Offer the wallet buttons — Apple Pay and Google Pay — because a thumbprint is faster than typing a card number on a phone, and phones are where most people will meet your form.
- A pre-selected middle preset to anchor the gift upward
- A "cover the fees" tick so the full amount reaches you
- Guest donations — no account required to give
- Apple Pay / Google Pay for one-tap mobile gifts
