Campaign Thermometer
A campaign thermometer is a visual progress indicator showing how close a fundraising campaign is to reaching its goal, creating urgency and social proof.
A campaign thermometer is a visual representation of fundraising progress that shows how much has been raised toward a campaign goal. Typically displayed as a vertical or horizontal bar that fills up as donations come in, it's one of the most effective tools for driving campaign momentum.
Why It Matters for Fundraising
Campaign thermometers leverage powerful psychological principles. Social proof — seeing that others have given — motivates new donors to participate. The progress effect — seeing a goal within reach — creates urgency as campaigns approach their target. Research shows that campaigns with visible progress indicators raise significantly more than those without. The key is showing real-time (or near-real-time) progress to maintain momentum.
Best Practices
Set realistic, achievable goals — a thermometer stuck at 10% discourages giving, while one at 70% energizes donors. Consider securing early gifts before launching publicly to show immediate progress. Update the display in real-time on your donation page. Use the thermometer in email appeals and social media to drive traffic to the campaign page.
