Carrier Correction Fee Estimator
Most Shopify merchants lose four figures a month to FedEx + UPS address-correction fees and never realize it - the line items hide in carrier invoices. Plug in your numbers, see the leak.
From your Shopify Analytics > Overview
International addresses fail ~3x more often
Carrier mix (% of orders)
Don't need to add to exactly 100 - we use the proportions you give. Any unaccounted carriers just don't add to the cost.

What Tacey would prevent
$412 / month saved
Tacey's AUTO-RESOLVE catches roughly 85% of carrier-correction-fee-triggering formatting issues (apartment in wrong field, non-standard street suffix, ZIP/city mismatches) and silently fixes them before the shipping label is created. The rest get held and the customer corrects via the fix page.

What this tool does
Quantify the silent four-figure leak in your carrier invoices
FedEx charges $25.50 and UPS charges $23.50 per package every time the address format doesn't match the carrier's database. Apartment in the wrong field, street suffix not abbreviated, ZIP/city mismatch - the package usually delivers fine, but the carrier bills the merchant for the 'correction' anyway. Most stores don't realize they're paying these until they audit their invoices line-by-line. This calculator estimates monthly cost based on your order volume, carrier mix, and international shipping percentage.
How to use it
Two minutes from inputs to dollars
- 1
Enter your monthly orders (Shopify Analytics > Overview > Sessions and Orders).
- 2
Enter your carrier mix as percentages: FedEx, UPS, USPS. Doesn't have to add to exactly 100 - we use proportions.
- 3
Enter the % of orders that ship internationally. International addresses fail at roughly 3x the rate of domestic.
- 4
Read the headline figure: monthly carrier cost from bad addresses, plus the breakdown by carrier and the Tacey-prevented amount.
Merchant tips
Reading the result honestly
These are blended industry averages: 2.1% domestic bad-address rate (Shippo), 6% international (Loqate). Your store's actual rate may be higher or lower depending on category, customer mix, and your current address-validation approach.
Tacey's AUTO-RESOLVE catches roughly 85% of carrier-correction-fee triggers (formatting issues that don't need customer input). The remaining 15% get held and the customer corrects via the fix page.
USPS doesn't charge correction fees, but failed-delivery reships still cost an average of $8 (return shipping + reprocess). We include this in the total.
The recommended-plan ROI is conservative: it counts only carrier savings. Tacey's plans also include the full Operations Toolkit (40+ tools), customer fix flow, fraud detection, and Intel Hub - none of which show up in this calculator.
When to use this
When this calculator earns its keep
Justifying Tacey to a CFO
The number this calculator produces is usually 5-15x Tacey's monthly cost. Show it next to the plan price.
Auditing carrier invoices
If the calculator says you should be paying $X in correction fees and your invoice shows 2x that, your label software has a formatting problem.
Quarterly board update
Track this number quarter over quarter as a KPI. It shrinks as you grow IF you have order-layer validation.
What you get out
Monthly cost breakdown + Tacey-prevented amount + recommended plan ROI
Headline monthly figure, three-card breakdown (FedEx fees / UPS fees / USPS reships), Tacey-prevented amount per month based on AUTO-RESOLVE catch rate, and net ROI vs the recommended plan tier for your order volume. All math is transparent - no hidden multipliers.
