How much are abandoned carts costing you?
The cart abandonment calculator that hands you a recovery plan
Cart abandonment rate is the percentage of shoppers who begin a checkout but leave before completing payment — calculated as (checkouts started − completed orders) ÷ checkouts started. The online average sits near 70%, per Baymard Institute's meta-analysis of 50+ studies, meaning that for most stores the revenue sitting in abandoned carts exceeds completed-order revenue at the same volume. This calculator gives you the abandonment rate, values the lost revenue at your average order value, and shows how much you can realistically recover — this period and annualized — based on channel-specific recovery benchmarks.
Seven in ten checkouts that start online never finish. That is not a typo — the Baymard Institute, which pooled 50+ separate studies, puts the average documented cart abandonment rate near 70%. For most stores the abandoned carts are worth more than the completed orders, which is exactly why recovery is one of the highest-leverage things a seller can work on.
The math is simple and we keep it transparent. Abandonment rate = abandoned carts ÷ checkouts started, where abandoned carts is just the checkouts that started minus the orders that completed. From there we value the abandoned carts at your average order value to get lost revenue, then apply your recovery rate to show recoverable revenue — and multiply both by how often the period repeats to annualize them. So a single monthly snapshot becomes a yearly opportunity figure.
Beyond the rate, this calculator carries the figure forward into a decision you can act on: is it worth building an email or SMS win-back flow, and what is the prize if you do? We surface realistic channel recovery benchmarks — email recovers about 5–15% of abandoned carts, SMS 8–18%, exit-intent offers 4–8%, retargeting ads 2–5%, and web push 3–7% — so the recovery rate you plug in is grounded, not a guess.
The tool is currency-agnostic. Your average order value is already in whatever currency you trade in, and the rate, completion rate, and recoverable share are universal ratios, so the answer comes out the same everywhere. We also keep sales tax, VAT, and GST out of the math: that money is collected from the buyer and remitted to the government, so it was never your revenue and folding it in would overstate what you can recover.

How it works
From checkout counts to a recovery opportunity
Four short steps — seconds to a benchmarked rate and an annual recovery figure.
02
Add order value & recovery rate
Your average order value puts a money figure on each lost cart, and your expected recovery rate sets how much you aim to win back.
03
Read your rate and lost revenue
Get your cart abandonment rate, the abandoned carts, and the gross lost revenue — with a verdict against the ~70% average.
04
See the recovery prize
We show the recoverable revenue at your rate, this period and annualized, so you know whether a win-back flow is worth building.

Formula
Exactly what the calculator computes
No black boxes — the abandonment, lost-revenue, and recovery math in plain algebra.
01
Cart abandonment rate
Abandonment Rate = (Carts Created − Completed Orders) ÷ Carts Created × 100
The share of started checkouts that never finished. Completed orders are capped at carts created (a completed order is, by definition, a started checkout), so the rate stays between 0% and 100%.
02
Abandoned carts & completion rate
Abandoned Carts = Carts Created − Completed Orders · Completion Rate = 100 − Abandonment Rate
The count of walked-away checkouts, and the flip side of the rate — the share that did convert. The two rates always sum to 100%.
03
Lost revenue
Lost Revenue = Abandoned Carts × Average Order Value
The gross potential revenue sitting in the abandoned carts this period. It uses average order value net of tax, since tax you collect is never your revenue.
04
Recoverable revenue
Recoverable Revenue = Lost Revenue × (Recovery Rate ÷ 100)
The realistic slice you can win back with a recovery flow. The recovery rate is a planning assumption — anchor it to channel benchmarks (email 5–15%, SMS 8–18%) rather than wishful thinking.
05
Annualized totals
Annual Lost = Lost Revenue × Periods/Year · Annual Recoverable = Recoverable Revenue × Periods/Year
Both figures scaled to a full year. Use 12 if the counts above are monthly, 52 for weekly, 365 for daily, or 1 if you already entered a whole year.
Worked example
1,000 checkouts, 300 orders, 80 average order value
Watch a single month of checkout data turn into an annual recovery figure.
Scenario
A store sees 1,000 checkouts started in a month and 300 of them turn into paid orders. Its average order value is $80.00. With a basic email win-back flow it expects to recover 10% of abandoned carts. What is the rate, and what is the recovery prize over a year?
1
Step 1 · Abandoned carts & rate
Carts created minus completed orders: 1,000 − 300 = 700 abandoned carts. As a rate that is 700 ÷ 1,000 = 70% abandonment, so 30% completion.
Abandonment rate: 70%
2
Step 2 · Lost revenue this month
Value the abandoned carts at the average order value: 700 × $80.00 = $56,000.00 of potential revenue that walked away this month.
Lost revenue: $56,000.00
3
Step 3 · Recoverable at your rate
Apply the 10% recovery rate: $56,000.00 × 10% = $5,600.00 you could realistically win back this month with a recovery flow.
Recoverable this month: $5,600.00
4
Step 4 · Annualize it
Multiply by 12 months: lost revenue $56,000.00 × 12 = $672,000.00 a year, and recoverable $5,600.00 × 12 = $67,200.00 a year.
Recoverable per year: $67,200.00
The takeaway
A 70% rate sits right on the ~70% online average, so demand is fine — the leak is at checkout. The headline is the $67,200.00 a year a modest 10% recovery flow could bring back. That is usually more than enough to justify building an email or SMS win-back sequence, and lifting the recovery rate just a few points moves the annual figure sharply.

Common mistakes
Where cart abandonment numbers go wrong
Confusing cart abandonment with checkout abandonment
Why it matters
Adding to cart and starting checkout are different funnel stages. Cart abandonment (measured from add-to-cart) runs higher than checkout abandonment (measured from checkout start), so mixing the two makes your rate look worse or better than it is.
Fix
Pick one consistent starting point — we recommend "checkouts started" — and count completed orders against the same set. Keep the denominator stable period to period.
Treating the rate as the whole story
Why it matters
A 70% rate is just a number until you attach money to it. Two stores with the same rate can be leaking wildly different amounts depending on order value and volume.
Fix
Always pair the rate with lost revenue and recoverable revenue, which is exactly what this calculator does — the money decides whether recovery is worth your time.
Assuming an unrealistic recovery rate
Why it matters
Plugging in a 40–50% recovery rate makes the annual prize look enormous, but no channel recovers that share of abandoned carts. The projection then drives bad decisions.
Fix
Anchor the recovery rate to channel benchmarks: email 5–15%, SMS 8–18%, exit-intent 4–8%, retargeting 2–5%, push 3–7%. Start conservative and raise it as your flows prove out.
Counting more completed orders than carts created
Why it matters
Every completed order is, by definition, a started checkout, so completed can never exceed created. Reversed or mismatched data sources produce a negative abandonment rate.
Fix
Check that both numbers come from the same period and the same funnel definition. This calculator caps completed at created and warns you when it has to.
Including sales tax / VAT in average order value
Why it matters
Tax you collect is remitted to the government — it was never your revenue. Folding it into order value inflates lost and recoverable revenue, overstating the prize.
Fix
Enter average order value net of tax. This calculator never touches sales tax, VAT, or GST in its math.
Forgetting to annualize
Why it matters
A single month's lost revenue can look small and easy to ignore, hiding a six-figure yearly leak.
Fix
Set "periods per year" to match your data (12 for monthly, 52 for weekly) so you see the full-year cost — the number that actually justifies investment.
Tips
Recover more abandoned carts
Surface total cost early
Unexpected shipping, tax, and fees at the final step are the single biggest reason carts get abandoned. Show the all-in price before checkout so there are no surprises.
Offer guest checkout
Forcing account creation drives shoppers away. Let people buy as a guest and invite them to create an account after the purchase, not before.
Build an email win-back
A short sequence — reminder within an hour, a nudge a day later, sometimes a small incentive — recovers 5–18% of carts depending on channel. Start with email, layer SMS on top.
Add an exit-intent offer
A well-timed offer or free-shipping nudge as the shopper tries to leave recovers another 4–8% before they ever abandon, often cheaper than chasing them afterward.
Cut checkout friction
Fewer fields, address autofill, and wallet payments (Apple Pay, Google Pay, UPI, etc.) cut friction. Every removed step lifts your completion rate.
Track the rate monthly
Re-run this calculator each month. A rising rate after a checkout change is an early warning; a falling one proves your fixes are working.
Use cases
When sellers reach for a cart abandonment calculator
The Cart Abandonment Calculator works across every stage of the workflow.
Justifying a recovery tool
Show the annual recoverable revenue to decide whether a paid email/SMS recovery app or flow is worth the subscription — the prize usually dwarfs the cost.
Diagnosing a checkout problem
A rate well above 80% signals friction, not weak demand. Use the figure to prioritise fixing shipping surprises, forced sign-up, or a clunky form.
Setting a recovery target
Model what a few extra points of recovery rate are worth per year, then set a concrete win-back goal for the marketing team.
Reporting to a founder or client
Translate a vague "our abandonment is high" into a hard annual lost-revenue and recoverable figure that makes the case for investment.
Comparing channels
Run the numbers at email vs SMS vs retargeting recovery rates to see which channel returns the most for the effort before you build it.
Forecasting after a checkout redesign
Estimate how much extra revenue a lower abandonment rate would unlock, to size the upside of a checkout overhaul.
Glossary
Cart abandonment vocabulary
Every important term you'll encounter in this calculator and the broader topic.
- Cart abandonment rate
- The share of started checkouts that never become a paid order: (carts created − completed orders) ÷ carts created. The online average is about 70%.
- Abandoned cart
- A checkout a shopper started — added items and began the process — but did not complete with a payment.
- Checkout completion rate
- The flip side of abandonment: the share of started checkouts that became an order. It plus the abandonment rate always equal 100%.
- Lost revenue
- The gross potential revenue sitting in abandoned carts: abandoned carts × average order value, net of tax.
- Recovery rate
- The share of abandoned-cart value you win back with a recovery effort. Varies by channel — email 5–15%, SMS 8–18%, exit-intent 4–8%.
- Recoverable revenue
- Lost revenue multiplied by the recovery rate — the realistic amount a win-back flow can bring back.
- Average order value (AOV)
- The average money value of a completed order, before sales tax / VAT / GST. Used to value each abandoned cart.
- Win-back flow
- An automated sequence (email, SMS, push) that reminds shoppers about an abandoned cart and nudges them to finish — the main tool for recovering lost revenue.
- Exit-intent offer
- A message or incentive shown as a shopper is about to leave the page, designed to recover the sale before the cart is ever abandoned.
Help & answers
Frequently asked questions
Everything you need to know about how the Cart Abandonment Calculator works.
01What is a cart abandonment calculator?
This calculator finds the share of started checkouts that never become orders and what that costs you. Enter checkouts started, completed orders, and average order value, and it returns your abandonment rate, lost revenue, and realistically recoverable amount — for the period and annualized.
02How do you calculate cart abandonment rate?
Cart abandonment rate = (carts created − completed orders) ÷ carts created × 100. If 1,000 shoppers start a checkout and 300 complete it, 700 carts are abandoned — 700 ÷ 1,000 = 70%. Completion is the flip side: 30% here. The two always sum to 100%.
03What is a good cart abandonment rate?
Baymard Institute's meta-analysis puts the average online rate at ~70%. Below 60% is strong, 60–70% around average, 70–80% high, above 80% very high and usually points to a checkout problem. Rates vary — travel and finance run higher; well-optimised stores can push below 60%.
04Why is the average cart abandonment rate around 70%?
Shoppers start checkouts to compare prices, save items, or browse — not always to buy. Add friction (surprise shipping, forced accounts, long forms, limited payment options) and the average hits ~70%. That is why fixing these levers recovers revenue more reliably than chasing more traffic.
05How much abandoned-cart revenue can I actually recover?
Recovery rates vary by channel: email typically recovers 5–15% of abandoned carts, SMS 8–18%, exit-intent offers 4–8%, retargeting 2–5%, and web push ~3–7%. Plug your expected rate into this calculator to see the realistic period and annual recovery prize.
06How is lost revenue from cart abandonment calculated?
Lost revenue = abandoned carts × average order value. 700 abandoned carts at an 80 AOV is 56,000 per period. Multiply by periods per year to annualize (×12 for monthly, ×52 for weekly). We exclude sales tax, VAT, and GST — that money goes to the government, not to you.
07What is the difference between cart abandonment and checkout abandonment?
Different stages of the same funnel. Cart abandonment starts from add-to-cart; checkout abandonment starts from checkout-start — lower, because checkout is further down the funnel. The key is consistency: pick one starting point, count completed orders against it, and never mix the two between periods.
08Why do shoppers abandon their carts?
Most common: extra costs revealed late (shipping, taxes, fees), forced account creation, a long or complicated checkout, and limited payment options. Most are fixable — surface total cost early, offer guest checkout, and trim the form to lift completion rate.
09What happens if I enter more completed orders than carts created?
Every completed order is by definition a started checkout, so completed can never exceed created. If your numbers come from mismatched sources and completed is higher, this calculator caps it at carts created, gives a 0% rate, and shows a warning. It never returns a negative rate.
10Does this cart abandonment calculator work in any currency?
Yes — abandonment rate and recovery rate are ratios and work in any currency. Enter your AOV in your local currency and the lost and recoverable revenue come out in that same currency. We exclude sales tax, VAT, and GST entirely — that money was never your revenue.
11How do I annualize my cart abandonment numbers?
Set "periods per year" to match your data: 12 for monthly checkouts, 52 for weekly, 365 for daily, or 1 for a full year already. The calculator multiplies lost and recoverable revenue by that number, turning a snapshot into the yearly figure that justifies a recovery flow.
12Is a high cart abandonment rate always bad?
Not necessarily — browsing and price-comparing inflate any rate. What matters is the recoverable slice: carts lost to fixable friction. This calculator pairs the rate with lost revenue and a realistic recoverable figure, so you can see how much is genuinely on the table to win back.
