Setting a Free Shipping Threshold That Does Not Lose You Money

Free shipping works. It is also the fastest way to ship your margin to a customer if the threshold is set by feel.

The number you need first

Not your rate. Your fully loaded cost per delivered order: freight, COD fee if applicable, GST, and your RTO cost spread across the orders that succeed.

For a typical seller shipping a 700 g parcel nationally with 60% COD and a 22% COD RTO rate, that lands somewhere around ₹150–₹190 per delivered order — well above the ₹80 freight line most people budget with.

The threshold formula

Set the threshold so the extra gross margin from the larger basket covers the shipping you are absorbing:

threshold ≥ shipping cost ÷ gross margin %

At ₹170 all-in shipping and a 40% gross margin:

₹170 ÷ 0.40 = ₹425

So a ₹425 basket generates ₹170 of gross margin — exactly enough to cover the shipping and nothing else. You want the threshold comfortably above that, because the point is to make money, not to break even. ₹599 or ₹699 against a ₹425 break-even is a sensible band.

Set it just above your current average order value

If your AOV is ₹520, a ₹599 threshold gives most customers a reason to add one more item, and that added item is where the profit is. A ₹1,200 threshold on a ₹520 AOV is invisible — nobody is doubling their basket for free delivery.

The rule of thumb that survives contact with reality: 10–25% above current AOV, and never below your break-even.

Two refinements worth making

Free shipping on prepaid only. You save the COD fee and, much more importantly, the RTO exposure. This one change often pays for the entire programme.

Zone-aware thresholds, if you ship a lot into Zone E. A national flat threshold means North East orders are subsidised by everyone else. Either raise the threshold for those pincodes or accept it as a customer acquisition cost — but decide it, do not discover it.

Frequently asked questions

Does free shipping actually increase orders?

Consistently, yes — shipping cost shown at checkout is among the most cited reasons for cart abandonment. The question is never whether it works, only whether the threshold is set high enough to pay for it.

Should the threshold be before or after discounts?

After. Otherwise a coupon can drop a ₹610 basket to ₹450 and you have given away both the discount and the shipping.

What about heavy or bulky products?

Exclude them, or set a separate threshold. A 12 kg volumetric parcel cannot ride on the same threshold as a 400 g one.
