A minimum order value should respond to a real order-cost constraint, not an arbitrary round number. Calculate the cost that occurs once per order and distinguish it from costs that rise with every item.
A threshold can reduce unviable small orders, but it may also turn away customers. The calculation does not predict that response.
Separate per-item and per-order costs
Per-item costs might include the product itself and individual preparation. Per-order costs might include an outer box, a fixed handling step or a fixed component of a fee.
Do not put the same packaging cost in both categories. Record which cost actually changes when a second item is added.
Use a consistent revenue basis and seek accounting advice where tax treatment affects the figures.
Build a simple contribution model
Suppose the products in a hypothetical basket contribute 40% of revenue before a fixed ₹80 per-order handling cost.
A ₹200 basket produces ₹80 at that stage and therefore leaves zero after handling. A ₹300 basket produces ₹120 and leaves ₹40.
This is a simplified mix assumption, not a universal margin or recommended minimum.
Add the contribution you need
If the business wants at least ₹100 remaining after the ₹80 handling cost in this model, it needs ₹180 before handling.
At a 40% contribution rate, the corresponding revenue is ₹180 ÷ 0.40 = ₹450.
That result depends on the product mix and excluded costs. It is not net profit unless every relevant expense has been accounted for.
Check low-margin baskets
A value threshold can be misleading when products have different contribution rates. A ₹450 basket of lower-contribution items may not produce the assumed ₹180.
Test representative combinations, including the least favourable ordinary mix. Do not rely only on the best-selling or highest-margin product.
You may need a different offer design rather than one store-wide threshold.
Compare alternatives
A minimum quantity, a small-order charge or a different packaging arrangement may address the cost more directly, where appropriate and clearly disclosed.
Do not add a surprise charge at the final step. Customers should understand the condition before investing effort in the purchase.
A threshold is one possible response, not an automatic requirement for every store with handling costs.
Consider the customer's task
If the business sells inexpensive replacement items, a high minimum may make the store impractical. If customers normally buy sets, the same threshold may be less disruptive.
Use actual baskets and enquiries where available. Do not assume buyers will add unnecessary products merely to reach a number.
A mathematically sufficient threshold can still be commercially unsuitable.
Define what counts towards the threshold
State whether the threshold uses product value before or after discounts and how delivery charges are treated. Configure the storefront to match the stated rule.
Check a basket just below, exactly at and just above the boundary.
If a coupon changes eligibility, explain the result clearly. The interface should not appear to contradict the advertised condition.
Observe the result carefully
After a controlled introduction, review small-order enquiries, abandoned attempts where measurable and contribution from completed orders.
Do not attribute every change to the threshold if other conditions changed at the same time.
A lower order count may be acceptable if the remaining work is sustainable, but that is a business decision requiring context.
Separate order value from delivery income
If delivery income is passed through to cover a courier cost, counting it towards the threshold may not create the product contribution the model assumes. Define the eligible subtotal explicitly. A ₹400 product basket plus ₹50 delivery is not automatically equivalent to ₹450 of product revenue.
Keep the model revisable
Update the handling cost and contribution assumption when packaging, fees or the product mix changes.
Record why the threshold exists so it does not remain permanently after the original constraint disappears.
The useful minimum is one that addresses a demonstrated cost while remaining understandable to customers. It should be supported by the actual basket economics, not copied from another store or chosen because the number looks familiar.
Examples are illustrative. Confirm current features, charges and suitability before making a business decision.
