Email marketing consistently shows best ROI of any channel - typically 30-50 per 1 spent. Depends on list size, send frequency, click rate, conversion rate, and order value. This calculator projects monthly and annual revenue.

10,000 subscribers × 4 sends/mo × 15% click × 2% conversion × 75 AOV = 900/mo = 10,800/yr. Against 50/mo platform cost (600/yr): 10,200 net = 1,700% ROI. Typical for active email programs.

Frequency matters - sending 2x weekly beats 1x monthly. But don't over-send (fatigue increases unsubscribes). 2-4 sends monthly is optimal for most brands.

Run it with sensible defaults

Using subscribers of 10,000, sends per month of 4, click rate of 15%, conversion rate of 2%, the calculation works out to 9,000.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Subscribers, Sends per Month, Click Rate %, Conversion Rate %, and Average Order Value — do not pull with equal force. 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.

How the math works

Monthly revenue = subscribers × click rate × sends × conversion × AOV. Annual = monthly × 12. Net = annual - platform costs. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using this as a check-in

Re-run this every three months. A single reading tells you where you stand; four readings tell you whether things are improving. The trend matters more than any individual snapshot.

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

10,000 subs × 4 sends × 15% × 2% × £75 £ = $9,000.00.

Inputs

Subscribers:10,000
Sends per Month:4
Click Rate %:15
Conversion Rate %:2
Average Order Value:75 £
Platform Monthly Cost:50 £
Expected Result$9,000.00

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