8 psychological principles for better donation forms

A good donation form makes it easier for supporters to decide. It clearly explains what a donation will be used for, suggests appropriate amounts and cuts out unnecessary steps. Psychological principles can help to make the donation process clearer and more motivating. It is crucial that these principles are applied transparently and responsibly.

Eight approaches are particularly relevant:

• suggested donation amounts as a guide
• visible campaign goals and progress
• credible social proof
• specific examples of the impact
• a genuine sense of urgency
• Reciprocity through valuable content
• Emotional and respectful storytelling
• As little friction as possible in the donation process

Not every principle is suitable for every organisation or campaign. You should therefore assess which adjustments are best suited to your cause, your supporters and the data you have available. Where possible, avoid changing everything at once; instead, test individual elements and compare the results.

Why psychology plays a role in donation forms

A donation is rarely a purely rational decision. Supporters weigh up various questions: Does the cause align with my beliefs? Can I trust the organisation? What impact will my contribution have? What is an appropriate amount? And how time-consuming is the donation process?

The donation form is the final step in this decision-making process. It should therefore not only function technically, but also reduce uncertainty and provide immediate answers to the most important questions.

Psychological principles can provide guidance here. However, they should not be used to put people under pressure. A responsibly designed form helps supporters make an informed decision that suits their own intentions and circumstances.

You can find out more about the fundamental motivations behind donations in the RaiseNow blog article on the psychology of giving.

1. Use suggested donation amounts as a helpful guide

Suggested donation amounts give supporters a starting point. Without such suggestions, they have to judge for themselves what contribution is customary or appropriate for the campaign. This can make the decision unnecessarily difficult.

At the same time, the amounts displayed act as reference points. They should therefore not be chosen at random. Base your decisions on your organisation’s actual donation figures and take into account the context of the specific campaign.

Different amounts may be appropriate for a local charity initiative than for an international emergency relief campaign. Furthermore, one-off and recurring donations should not automatically be offered the same suggestions.

A sensible selection could, for example, consist of three or four amounts plus a free text field. It is important that even smaller donations remain visibly welcome.

When making your selection, bear the following points in mind:

• Use existing donation data as a basis.
• Choose amounts that are appropriate for the occasion and the target audience.
• Avoid unrealistically high suggested amounts, which could put people off.
• Always offer the option to enter a custom amount.
• Treat one-off and recurring donations separately.

Rather than simply using the highest amount as a psychological contrast, each option should be objectively justifiable. This ensures the form remains credible and fair.

2. Make campaign goals and progress visible

A specific goal makes a campaign easier to understand. Supporters can see not only that money is being raised, but also what is to be achieved together.

A progress bar can visualise this development. It is particularly helpful for time-limited fundraising drives, crowdfunding campaigns or projects with a clearly defined funding target.

For a progress indicator to build trust, the underlying information must be accurate and up to date. Also explain what the target relates to. A sum of 20,000 Swiss Francs is more meaningful if it is clear which project is to be funded with it.

As well as the total amount raised, you can highlight other relevant milestones, for example:

• the proportion of the project that has already been funded
• the amount still required to reach the campaign target
• the number of sub-goals achieved
• the duration of the campaign

However, a progress bar is not essential for every donation form. In the case of general recurring donations or long-term organisational goals, a target display that appears artificial may raise more questions than it answers. You should therefore only use one if there is a clear and verifiable target.

3. Use social proof credibly

People often take their cue from the behaviour of others. In fundraising, social proof can demonstrate that an organisation is already receiving support and that other people identify with its cause.

Possible social proof elements include testimonials from supporters, actual donation figures, campaign updates or short personal accounts. They can help build trust, provided they are relevant, up-to-date and verifiable.

Only use figures for which you have a reliable data source. Phrases such as ‘Join thousands of supporters’ should not be used if they cannot be clearly substantiated.

Data protection is equally important. Names, comments or donation amounts may only be published if the individuals concerned have given their consent.

Credible social proof might look like this, for example:

386 people have already supported this campaign.

Or:

“I’m supporting this project because the aid goes directly to our region.”
Anna M., campaign supporter

Social proof should complement the content of the form, not dominate it. A single, relevant statement is often more helpful than a long feed of constantly changing notifications.

4. Explain the impact of a donation in concrete terms

A sum of money remains abstract as long as it is unclear what can be achieved with it. Examples of the impact establish a clear link between a donation and the project being supported.

For example, an organisation can explain what a specific contribution helps to fund on a pro rata basis. However, the information must be factually correct and match the actual use of funds.

Examples of the impact should therefore be developed in collaboration with the relevant programme or project teams. Check regularly whether costs, outputs and wording are still up to date.

One possible presentation is:

• CHF 25 helps to provide the necessary materials.
• 50 Swiss Francs contribute to the provision of a consultation.
• 100 Swiss Francs help to finance a significant portion of the project costs.

If a donation cannot be clearly linked to a specific service, this should be stated transparently. Avoid giving the impression that every single donation directly funds the stated purpose if the funds are in fact used flexibly within the project.

A suitable way of phrasing this could be:

For example, with a donation of 50 Swiss Francs, you’ll help us to fund the necessary materials and the implementation of the project.

Examples of the impact work best when they are specific enough to be understandable, but do not convey a false sense of precision.

5. Clearly communicate genuine urgency

A sense of urgency can help supporters understand the time-sensitive nature of a donation. It is particularly useful in the case of acute crises, seasonal campaigns, binding project deadlines or time-limited matching fund schemes.

It is crucial that the urgency is genuine. Artificial scarcity, countdown timers that are constantly reset, or unsubstantiated claims such as ‘Help today only’ can damage trust.

Instead,communicate clearly:

• why support is needed right now
• the actual deadline
• what is to be achieved by that point
• what conditions apply to a ‘double your donation’ campaign
• what will happen once the deadline has passed

A clear way of phrasing this might be, for example:

Donations received by 15 December will be matched by our funding partner up to a total of 10,000 Swiss Francs.

This statement is more specific than a general reference to a ‘one-off opportunity’. Supporters understand what the conditions are and how their donation will be used.

6. Offer genuine added value before asking for a donation

Reciprocity describes the human tendency to respond positively to a favour or gesture of kindness received. In fundraising, this principle should not be seen as a barter arrangement. Rather, it is about building a relationship before making a request for a donation.

Organisations can, for example, share knowledge, insights or helpful resources:

• a clear impact report
• up-to-date information on the project
• a guide on the relevant topic
• transparent insights into how funds are used
• specific ways to get involved even without making a donation

Content like this demonstrates expertise and builds trust. It helps potential supporters to better understand the cause and make an informed decision.

However, avoid linking free content to an unspoken moral obligation. Anyone who downloads a report or takes part in a webinar does not owe the organisation a donation.

In responsible fundraising, reciprocity therefore does not work through pressure, but through relevant communication and a long-term relationship.

7. Building rapport through stories

Stories make complex topics understandable. They show how a problem affects the everyday lives of real people, communities or projects. On a donation form, such a story must be brief enough to support the donation process rather than interrupt it.

An effective story ideally answers three questions:

1. Who or what is it about?
2. What is the challenge?
3. How does the donation contribute to the solution?

Ensure the narrative is respectful. People supported by a project must not be reduced to their need for aid or used merely as a means to elicit an emotional response. Their dignity, self-determination and consent must always be respected.

Also, avoid generic stories with no verifiable link to the project. A specific example should be authentic and reflect the actual work of your organisation.

Instead of a dramatic but vague statement, a factual and personal account can have a greater impact:

At the youth centre, children and young people find a safe place to learn and take part in group activities. With your donation, you are supporting the staff, the materials and the ongoing programmes.

The story creates a sense of connection, whilst the impact of the donation remains clear.

8. Reduce friction in the donation process

Supporters should be able to make a donation without unnecessary detours. Every additional field, every unclear phrase and every avoidable intermediate step increases the effort required.

A frictionless donation form therefore only asks for information that is actually required. At the same time, it must clearly explain which data is being processed and why.

Check the following in particular:

• Is the form easy to read and use on a smartphone?
• Is the key information immediately clear?
• Are only the necessary mandatory fields used?
• Are error messages clearly worded?
• Is it easy to select the amount and payment method?
• Is it clear whether this is a one-off or a recurring donation?
• Does the entire process work with a keyboard and assistive technologies?
• Are loading times and redirects kept to a minimum?

The experience should remain consistent even after submission. A clear confirmation page and a prompt thank-you message show that the donation has been successfully received and is appreciated.

RaiseNow offers donation forms for one-off and recurring donations, which can be shared online or embedded on your own website. Forms, transactions and supporter data are managed centrally in RaiseNow Hub.

How to optimise your donation form step by step

The eight principles should not be implemented all at once and without a data-driven approach. Otherwise, it is almost impossible to assess which change contributed to which result.

Start by taking stock:

Next, select a single adjustment. For example, you could revise the suggested amounts, add a statement of impact or remove an optional form field.

Afterwards, monitor how relevant metrics develop over a sufficiently long period. Depending on your objectives, these may include, amongst others:

• completed donations
• Form abandonment
• average and median donation amount
• Ratio of one-off to recurring donations
• Usage by device type
• Use of suggested and customised donation amounts

When analysing the results, also take external factors into account. The campaign period, target audience, communication channel or current events can influence donation behaviour. A result cannot therefore automatically be applied to all future campaigns.

A well-designed donation form makes it easier to make an informed decision

Psychological principles can make donation forms easier to understand and more accessible. However, trust remains the strongest foundation. Supporters should be able to recognise who is behind a campaign, what happens to their donation and what decision they are making.

Suggested donation amounts provide guidance. Examples of the impact make the cause tangible. Stories create a sense of connection. A simple process prevents technical or content-related obstacles from disrupting an existing intention to donate.

The most important rule is therefore: do not optimise at the expense of transparency. A donation form that is successful in the long term combines a good user experience with honest communication and a respectful approach to supporters.

Frequently asked questions about psychologically optimised donation forms

Which psychological principles are suitable for donation forms?

Particularly relevant are guidance through suggested amounts, concrete examples of impact, credible social proof, genuine urgency, respectful storytelling and a donation process that is as simple as possible. Which approach makes sense depends on the campaign, the target audience and the available data.

Are psychological principles in fundraising manipulative?

Not necessarily. It depends on how they are used. A donation form is designed responsibly if it presents relevant information clearly and allows donors to make a free choice. Artificial time pressure, misleading amounts or unsubstantiated claims about impact, on the other hand, are problematic.

How do I choose the right suggested donation amounts?

Use your previous donation data as a starting point and examine both the average and the median amount. Also take into account the occasion, the target audience and the type of donation. Always offer a field for a freely chosen amount alongside the suggested amounts.

How many donation amounts should a form display?

A small, clear selection is usually easier to take in than a large number of options. Three or four suggested amounts, plus a field for a custom amount, can be a good starting point. However, the appropriate number should be assessed based on how the specific form is used.

What is an example of the impact of a donation?

An example of the impact explains what work a specific donation amount enables or supports. It should be based on actual project costs and updated regularly. If a clear link cannot be established, the wording must make it clear that this is an example.

Should I preselect one-off or recurring donations?

A default setting influences the decision and should therefore be used transparently. Supporters must be able to clearly see at all times whether they are making a one-off or a recurring donation. Both options should be easy to understand and accessible without any hidden defaults.

Which area should I optimise first?

Start with basic hurdles. Check the mobile experience, the length of the form, the clarity of the donation amounts and how the impact is presented. These areas directly affect the user experience and can often be assessed more clearly than additional psychological elements.

Can I apply several principles at the same time?

Yes, provided the individual elements complement each other and the form remains clear and uncluttered. Too many messages, counters, notes and options can compete with one another. You should therefore set priorities and, where possible, test major changes one at a time.

How do I measure whether an adjustment is working?

Before making the change, define a specific question and a suitable metric. Then compare the results with a previous period or a suitable control group. Take into account campaigns, channels and seasonal influences before drawing any conclusions.

What makes for a good experience after a donation?

A clear confirmation, transparent information on how the donation will be processed, and a fitting thank-you are all part of a complete donation experience. Post-donation communication should be consistent with the campaign and should not overwhelm supporters with further requests straight away.
