Social media ROI is tricky because most value is indirect: brand recall, trust, future purchases. This calculator focuses on the measurable part - followers gained, engagement, conversions, and revenue in a defined period. The headline is monthly ROI as a percentage of spend.

Spending 5,000/month gaining 2,000 new followers at 3% engagement = 60 engaged users. At 1% purchase conversion = 0.6 conversions. At 500 average customer value = 300 revenue. That's -94% ROI for the direct attribution. Most social media channels look terrible on this narrow measurement.

The real argument for social is compound: followers in month 1 might not buy until month 8. A 3-year-old Instagram follower is worth more than a new one. If you can only justify social by direct ROI, you're probably over-spending or targeting the wrong audience. Brands that win on social treat it as an 18-24 month investment, not a monthly ROI campaign.

Quick example

With monthly social spend of 5,000 and followers gained monthly of 2,000 (plus engagement rate of 3% and conversion rate of 1%), the result is -94.00%. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Monthly Social Spend, Followers Gained Monthly, Engagement Rate %, Conversion Rate %, and Avg Customer Value. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

What's happening under the hood

Engaged = followers × engagement %. Conversions = engaged × conversion %. Revenue = conversions × value. ROI = (revenue - spend) / spend × 100. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

What the score tells you

Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

£5,000 £ spend → 2,000 followers × 3% engagement × 1% conversion = -94.00%.

Inputs

Monthly Social Spend:5,000 £
Followers Gained Monthly:2,000
Engagement Rate %:3
Conversion Rate %:1
Avg Customer Value:500 £
Expected Result-94.00%

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Sources & Methodology

Methodology

Engaged = followers × engagement %. Conversions = engaged × conversion %. Revenue = conversions × value. ROI = (revenue - spend) / spend × 100.

Frequently Asked Questions

Why is my social ROI negative?
Most brands show negative direct ROI on social. The measurable conversion rate from social is usually 10-30% of what paid search delivers. The real value comes from brand compounding - customers who see you 20 times over 2 years eventually buy.
What's a good engagement rate?
1-3% is average, 3-6% is strong, 6%+ is excellent. Micro-influencer accounts (<10k followers) often show 5-15%; mega-accounts (>1M) usually settle at 0.5-1.5% due to algorithm dilution.
Should I count brand searches?
Yes, if you can attribute them. Google Analytics shows brand-name searches; these often spike after big social pushes. Many social managers report this as 'organic' channel revenue but it's really social-driven.
What's the right attribution window?
Last-click attribution under-counts social massively because social followers often convert via direct or paid search later. Use 28-day view-through attribution minimum. Even then you'll miss the 3-12 month compounding effects.
