Why a fundraising thermometer works
Donors give more when they can see a goal and how close you are to it. A thermometer turns an abstract target into a picture anyone understands at a glance, creates momentum as the fill rises, and shows supporters that their gift will help close the gap. Update it often and mention it in emails, newsletters, and social posts.
Tips for a better fundraising thermometer
Set a realistic goal you can reach, so the thermometer fills visibly. Use a clear title that says what the money is for. Place it above the fold next to your donate button. Update it at least weekly, and celebrate milestones at 25%, 50% and 75%.

Frequently asked questions
What is a fundraising thermometer?
A fundraising thermometer is a visual chart that shows how close a campaign is to its goal — like a real thermometer, the "mercury" rises as more money is raised. It motivates donors by making progress concrete and visible. Fundraising thermometers have been used by charities, schools, and churches for decades; the online embeddable version was first published in 2009.
Is it really free?
Yes. The Original thermometer style is free forever — no account, no credit card, no time limit. It includes a small thermometerchart.net watermark. Premium ($49/year) removes the watermark, unlocks all 28 styles, enables custom colors, and adds Google Sheets live sync. Pro ($8 for 5 styles of your choice) also removes the watermark.
How do I embed a thermometer on my website?
After creating your thermometer you'll get a one-line embed code: an
<img> tag pointing to your chart. Paste it into any page that accepts HTML — WordPress, Squarespace, Wix, raw HTML, or even an email. No JavaScript is needed on your site. The chart is a plain image that updates on each page load.Can I update the amount raised without recreating the thermometer?
Yes. Free users can update their goal and current amount anytime using the edit link — the embedded chart reflects changes on the next page load. Pro users can connect a Google Sheet so the chart updates automatically whenever the spreadsheet changes, with no manual editing needed.
Does the thermometer work in WordPress?
Yes. Because the embed code is a plain
<img> tag, it works anywhere WordPress accepts HTML — in a post, page, widget, or a Custom HTML block in the Gutenberg editor. No plugin is required.How long has thermometerchart.net been online?
The thermometer tool was first published on July 22, 2009 — predating most competitors. thermometerchart.net launched as a dedicated domain to expand the tool with more styles, Pro features, and Google Sheets integration.
