About this calculator
Average cart abandonment rates run 65-75% across ecommerce, meaning most site traffic that adds to cart never completes checkout. That abandoned value is recoverable through email flows, SMS, and retargeting ads, typically recovering 5-15% of abandoned cart value depending on flow quality and timing. This calculator takes your monthly site sessions, add-to-cart rate, average cart value, and current checkout completion rate, computes the total abandoned cart value sitting on the table each month, then applies a realistic recovery rate to show what improving your recovery flow is actually worth in dollars. Enter monthly sessions, percentage that add to cart, average cart value, current checkout completion rate, and your assumed recovery rate for abandoned carts. The output shows total abandoned value per month and recovered revenue at your assumed rate, which justifies the investment in a proper three-email (or email+SMS) abandonment sequence versus relying on Shopify's default single email.
Worked example
Using the values the calculator loads with:
Inputs
- Monthly site sessions: 40000
- Add-to-cart rate: 8 %
- Average cart value: 62 $
- Checkout completion rate (of carts): 28 %
- Assumed recovery rate on abandoned carts: 8 %
Results
- Recoverable revenue per month: $11,428
- Total abandoned cart value/month: $142,848
- Abandoned carts per month: 2,304
- Carts created per month: 3,200

FAQ
What recovery rate should I assume?
A well-built three-email flow (roughly 1 hour, 24 hours, 72 hours after abandonment) typically recovers 5-10% of abandoned cart value; adding SMS to the sequence can push combined recovery to 10-15%. A single generic email recovers closer to 2-4%.
Why is checkout completion rate different from conversion rate?
Overall site conversion rate (purchases ÷ all sessions) is diluted by browsers who never add to cart. Checkout completion rate here specifically measures what happens after someone has already added an item, which is the more relevant number for recovery flow ROI.
Does this include browse abandonment, not just cart abandonment?
No, this specifically models cart abandonment (item added, checkout not completed). Browse abandonment (viewed a product, never added to cart) is a separate, larger and lower-intent audience that needs a different, lighter-touch flow.
What's the biggest lever for improving recovery rate?
Send timing and offer strategy matter most: the first email within an hour with no discount, the second at 24 hours with urgency messaging, and the third at 48-72 hours with a modest incentive (5-10% off) typically outperforms any single-email approach by 2-3x.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
