The verdict in three sentences
Unconditional free shipping destroys margin; always-paid shipping stalls the purchase. The right setting is a threshold calculated at about 1.3 times your average cart, which nudges the buyer to add an item to reach it. Done well, this threshold lifts average order value (AOV) by 15 to 25 % while preserving margin.
The threshold, a psychological and financial lever
A buyer in Kampala who sees "just 4,000 FCFA more for free shipping" almost always adds a product. It is more rewarding for them (shipping feels free) and for you (bigger cart, shipping cost absorbed). The threshold must cover shipping cost + margin so you never sell at a loss.
| Shipping strategy | Effect on AOV | Effect on margin | Risk |
|---|---|---|---|
| Always free | Neutral | Negative | Eroded margin |
| Always paid | Negative | Neutral | High abandonment |
| Threshold = avg cart | +8-12 % | Stable | Low |
| Threshold = 1.3x avg cart | +15-25 % | Positive | Low |
| Threshold too high (2x+) | +5 % | Positive | Frustration |
| Cheaper pickup point | +5-10 % | Positive | Logistics |
Calculate your threshold in three steps
The method is simple and should be recomputed each quarter as the average cart evolves.
| Step | Data | Kampala example |
|---|---|---|
| 1 | Current average cart | 15,000 FCFA |
| 2 | Multiply by 1.3 | 19,500 FCFA |
| 3 | Round to a clean threshold | 20,000 FCFA |
| Check | Shipping cost + margin | 2,500 FCFA -> ok |
| Message | "Just X more for free shipping" | dynamic |
Threshold-hit rates run around 30 to 45 % of carts: those who reach it grow their basket, those who do not pay shipping. Either way, your margin is protected.
Mini case study
Kossi runs an online delicatessen in Kampala. Average cart: 15,000 FCFA across 80 orders/month, or 1,200,000 FCFA monthly revenue. He sets the free-shipping threshold at 20,000 FCFA (1.3x).
Result: about 40 % of buyers grow their cart to reach it, lifting AOV by 20 %, to 18,000 FCFA. New revenue: 80 x 18,000 = 1,440,000 FCFA/month, or +240,000 FCFA/month and +2,880,000 FCFA/year (2026 estimate), while absorbing shipping on the larger carts.

FAQ
How do I set the free-shipping threshold?
Multiply your average cart by 1.3 and round to a clean figure. Then check the threshold covers at least shipping cost plus your margin, otherwise you sell at a loss on the carts that reach it.
Is always-free shipping a bad idea?
Often, yes. It reassures but erodes margin on every order, including small carts. A well-calibrated threshold keeps the reassuring effect while protecting profitability.
What if my average cart is very low?
A 1.3x threshold still works, but also consider a cheaper pickup point and bundles (2 for X). The goal is to make adding an item economically logical.
How often should I recompute the threshold?
Each quarter, or whenever your average cart moves more than 10 %. A frozen threshold quickly becomes too low (lost margin) or too high (frustration and abandonment).
Does the "just X more" message really help?
Yes, it is one of the most effective checkout messages. It turns an unwanted cost into a reachable goal and pushes 30 to 45 % of buyers to grow their cart.
