How accurate are these estimates? +
The estimates are based on real-world benchmarks specifically from the UK third sector. While Meta's auction fluctuates, our tool uses average CPM, CPL, and CPA data observed across hundreds of charity campaigns to give you a 'rough and ready' baseline.
What difference do Objectives and Goals make? +
Objectives (like Awareness or Leads) tell Meta what you want to achieve, while Optimisation Goals (like Reach or Instant Forms) tell the algorithm which specific actions to prioritise. Misalignment here is the #1 reason for wasted ad spend.
What happens after I hit 'Calculate'? +
You'll receive your results on-screen. If you'd like a PDF summary via email, just enter your email address and we'll get this over to you.

Want to know more about Facebook ads for charities?

We run Facebook ad campaigns for a wide range of UK charities, from small local ones to larger national charities. If you're looking to raise awareness, reach more of the people you exist to help, create a community of supporters, and acquire donations, there's no question about it: you need to be running ads on Facebook.

They work because they allow you to choose the audience, enable you to reach significantly more people than you can just by posting organic content on your Facebook page (did you know that only around 10% of your Page fans and followers will ever see your posts?), and give you access to additional analytics tools that you can use to guide your advertising strategies.

Here are some of the common questions we get asked about Facebook ads for charities and non-profits.

What is a good cost per lead for a UK charity Facebook campaign in 2026?

The cost will vary depending on whether you're capturing leads on Facebook using Instant Forms, or on your website. Instant Form leads tend to be less expensive, but also less qualified. Our calculator will provide a solid indication based on the optimisation goal you select.

How do I calculate the potential reach of a £2,000 charity Facebook ad budget?

The cost of reaching Facebook users with ads is usually expressed as Cost per Thousand (CPM). Take the benchmark figure (£/CPM) and divide it by a thousand first. Then divide your total budget by this figure. Our calculator is already programmed to do this for you with real-world CPM values.

Which Meta campaign objective is best for UK charity donor acquisition?

The Sales objective is generally best for donation campaigns. At the AdSet level, you'll provide details of the Conversion location (usually your website or landing page), performance goal (you'll typically set this to 'maximise number of conversions'), dataset (the specific Meta Pixel you'll use for tracking) and conversion event (the action that you want people to take when they see your ads - select 'Donate' from the dropdown list of options). Use our calculator to get a feel for what you could expect to pay per conversion with a donation campaign.
