Enter your donation form data per month
Everyone who opened or started your donation form, from your form or platform analytics.
Gifts that finished payment in the same window, from your CRM or processor.

Form conversion rate
Drag the blue marker to model any target rate. Funraise's placed form converts 31%, its pop-up form 38%.
Add your donation form opens and completed donations above. The best competing forms convert about 30%; Funraise pop-up forms convert 38%.
Funraise pop-up forms turn 38% of starts into completed payments, 28% better than the next best form, and even the inline placed form converts 31%, matching the leading competitor. Switching a plain donation link to a pop-up form lifts conversion 78% on its own. With the average online gift at $281 and 87% of donors covering their own fees, every point of form conversion compounds.
Your form conversion rate and revenue upside in three steps
Form conversion rate is the last and most leveraged step in online giving: it measures how many of the donors who start your form actually finish paying. Every abandoned form is a donor who already decided to give and then hit friction. This calculator turns three numbers into a benchmarked rate and a clear revenue opportunity.
Enter three numbers
Add your donation form opens, completed donations, and average gift for a month, year, or single campaign. The calculator instantly returns your form conversion rate, total raised, and where you land against the benchmarks.
Compare to the benchmarks
See your rate against the best competing forms at about 30% and Funraise forms that convert 31% (placed) to 38% (pop-up, 28% better than the next best form), so you know instantly whether your form is leaking donors at checkout or already ahead.
Model the revenue you're leaving on the table
Drag the target slider to any conversion rate and watch the recovered donations and dollars update in real time. It is the fastest case you can make for investing in a higher-converting donation form.
How to calculate donation form conversion rate
Donation form conversion rate is completed donations divided by the number of people who opened or started your donation form, expressed as a percent. If 2,000 people started your form last month and 480 finished giving, you converted at 24%. Unlike page conversion rate, which measures visitors who reach your page, form conversion rate isolates the checkout itself: it tells you how many donors who already decided to give actually made it through, which is why it belongs on every fundraising dashboard.
The benchmark to clear is the best competing forms, which convert about 30% of starts into completed gifts. Funraise forms go further: the placed (embedded) form converts 31%, matching the leading competitor, and the pop-up form converts 38%, 28% better than the next best form. The gap matters because form conversion sits at the very bottom of the funnel, in front of every dollar you already spent to get a donor to the form. Lifting it is almost always cheaper than buying more traffic.
Why forms leak donors at checkout: too many fields, no recurring option, no mobile-first layout, a slow or redirecting payment step, and a checkout that does not feel safe. Switching a plain donation link to a pop-up form lifts conversion 78% on its own. Funraise's average one-time gift is $281 (2x the benchmark) and 87% of donors cover their own processing fees, so every donation you recover flows almost entirely to the bottom line. Pair this tool with the Donation Page Conversion Rate Calculator and the rest of the Funraise free tools to turn a higher rate into a revenue plan.
Questions?
What is a good donation form conversion rate?
The best competing donation forms convert about 30% of starts into completed gifts, so anything near that is solid and anything below it has clear room to grow. Best-in-class forms do better: Funraise's placed form converts 31% and its pop-up form converts 38%, which is 28% better than the next best form. Use this calculator to see exactly where your form lands and how much closing the gap is worth.
How do I calculate my donation form conversion rate?
Divide your completed donations by the number of people who opened or started your donation form, then multiply by 100. For example, 480 completed donations from 2,000 form opens is a 24% conversion rate. Enter those two numbers above (plus your average gift) and the calculator does the math, benchmarks the result, and shows the revenue impact of a higher rate.
What's the difference between donation form and donation page conversion rate?
Donation page conversion rate is completed donations divided by everyone who visited the page; donation form conversion rate is completed donations divided by everyone who actually opened or started the form. Page rate captures the whole funnel including people who never engaged; form rate isolates the checkout step, so a low form rate points straight at friction in the form itself. Many teams track both: use this tool for the form, and the Donation Page Conversion Rate Calculator for the page.
Where do I find my form opens and donations numbers?
Pull form opens or starts from your donation platform's form analytics or an analytics event on the form-open action. Completed donations and average gift come from your CRM, payment processor, or giving platform reports. Match the timeframe for opens and donations so the rate is accurate.
How can I increase my donation form conversion rate?
The highest-impact moves are reducing form fields, making the form fast and mobile-first, keeping the donor on-page through payment instead of redirecting, prompting recurring gifts, showing suggested amounts tied to impact, and offering fee coverage. Switching a plain donation link to a pop-up form alone lifts conversion 78% on average, and Funraise pop-up forms convert 38% of starts into completed payments.
Does this calculator save or share my numbers?
Your inputs save in your browser's local storage so they are there when you come back, and nothing is sent to a server unless you copy a share link. Use the share link to send your benchmarked result to a colleague or your board; they will open the same scenario, ready to adjust.
