How many repeat buyers pay back free first-order shipping?
Offering free shipping to every new customer is an investment, and a quick payback calculation tells you how many of them must come back for it to make sense.
"Free shipping on your first order" is a common welcome offer. It feels generous and it removes a reason to hesitate. But it is also a cost you pay before you know whether the customer will ever return. Treat it like any other investment and ask how long it takes to pay back.
The cost of the offer
Suppose 100 new customers place first orders in a month and each ships free, costing you Rs 70.
100 customers times Rs 70 is Rs 7,000.
That Rs 7,000 is your spend for the welcome offer, assuming you would otherwise have charged shipping to them.
How many repeat orders pay it back
Now think about the repeat order. Say each repeat order earns Rs 200 in profit after all costs, including its own shipping.
Rs 7,000 divided by Rs 200 is 35.
You need 35 repeat orders to recover the cost. If each returning customer buys once more, that means 35 of your 100 new customers must come back. Put another way, a little over a third must reorder before the offer breaks even.
If some come back twice, you need fewer customers. If fewer come back, the offer remains a loss, a marketing cost you paid for goodwill.
How realistic is that bar?
I cannot tell you what share of your customers will return. It depends heavily on what you sell. A consumable like tea or skincare invites reorders. A once-in-a-lifetime purchase, like a large decorative piece, does not. Look at your own order history. How many customers from three months ago have bought again? That number replaces my guess.
If you have no history yet, treat your first 100 orders as a test and measure the repeat share before making the offer a permanent policy.
Make the offer cheaper to run
- Restrict free shipping to first orders above a minimum value, so the extra cost is attached to a bigger sale. Our post on free shipping thresholds helps find a safe floor.
- Cap it at a certain number of shipments a month if cash is tight.
- Tie it to joining your email list, so you earn a way to contact them again. Read building an email list from day one.
- Include a reorder reason in the parcel, such as a small note about a refill or a complementary product.
Pair it with a repeat plan
The offer only pays back if customers have a reason to return. A welcome offer without any follow-up is a gamble. Plan the second purchase before you pay for the first. Our piece on why the repeat customer is the whole business explains why that second order is where profit tends to show up, and email for repeat sales covers how to ask for it.
Compare with the alternatives
Free shipping is not the only way to welcome new buyers. A small coupon, a sample or a better unboxing experience may cost less per customer. Work the same payback formula on each option and compare the repeat orders needed.
The short version
Multiply new customers by shipping cost, divide by profit per repeat order, and you get the repeat orders needed. If that number looks achievable from your own history, go ahead. If it looks like a stretch, shrink the offer, restrict it or choose a cheaper welcome gesture.
