Calculate the Revenue You're Leaving on the Table by Not Using Testimonials

Testimonials are one of the highest-ROI marketing investments you can make — but most businesses have no idea what they're worth. This calculator shows you the real revenue impact of your current social proof, and what you could be making with a stronger testimonial strategy.

What it does

Put a dollar figure on social proof

Social proof "feels" important, but it's hard to justify investment without numbers. This calculator uses your traffic, conversion rate, and average order value to show the specific revenue uplift you'd see from improving your testimonial strategy by 10%, 25%, or 50%.

Built on real conversion research

The estimates are based on published research and Senja's own data across thousands of businesses. You'll see the conversion uplift ranges for adding testimonials to key pages — homepage, pricing, checkout — and what that translates to in your specific revenue context.

A business case for investing in social proof

If you need to convince a co-founder, a client, or yourself that testimonials are worth the time, this calculator gives you the numbers. Print it, share it, use it — it's the business case for taking social proof seriously.

How it will work

Enter your current business metrics

Input your monthly website visitors, current conversion rate, average order value, and how many testimonials you currently display. These form the baseline for your calculation.

See your Social Proof Gap

The calculator shows you where you sit on the social proof spectrum — from "leaving a lot of money on the table" to "maximising proof potential." It highlights your biggest untapped opportunities: which pages to add testimonials to first.
