Should I offer a partial refund?

For minor damage, late delivery, or a small mismatch, a partial refund often costs less than a return and keeps the review. Compare it against a full refund and a replacement before you offer.

How much should a partial refund be?

Start from the maximum refund before loss shown above, then offer the smallest amount that genuinely resolves the buyer's issue. Many sellers land between 10% and 30% of the order.

How do I know if I'm over-refunding?

If the refund is larger than the profit left on the order, the order becomes a loss. The profit-after-refund figure tells you exactly where that line sits.

How do I calculate the true cost of a return?

Add the refund, product cost, shipping both ways, packaging, and non-refundable fees, then subtract anything you can resell.

What this means

A partial refund is usually cheaper than a return because you keep the fees you already paid but skip return shipping. The "maximum refund before loss" number is your negotiating ceiling. This is a planning estimate only — not legal, tax, financial, or platform-policy advice.

All calculations are estimates based on average platform fees. Real profits may vary depending on category, ads, and shipping.

Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.

When to use this calculator

A buyer reports minor damage, a small defect, or a late delivery and you want to keep the sale.
You want a firm ceiling before you start negotiating a discount with a customer.
Return shipping would cost more than the goodwill discount the buyer is asking for.
You're deciding between a partial refund, a full refund, and a replacement.

Formula

Order revenue = Sale price + Shipping charged · Fee = Revenue × Fee% + Fixed fee · Original profit = Revenue − Product − Shipping − Packaging − Fee · Profit after refund = Original profit − Refund + Recovery · Max refund before loss = max(Original profit + Recovery, 0)

Worked example

$60 sale, $5 shipping charged, $18 product, $7 shipping paid, $1.50 packaging, 6.5% + $0.30 fees, $15 partial refund.

Revenue = $65
Fee = 4.23 + 0.30 = $4.53
Original profit = 65 − 18 − 7 − 1.50 − 4.53 = $33.97
After $15 refund = $18.97
Max refund before loss ≈ $33.97

Answer: ≈ $18.97 profit left; up to about $33.97 before a loss

How it works

Partial refunds are usually the cheapest way to resolve a minor issue: the customer keeps the item, you skip return shipping, and you avoid a full loss. The maximum-refund figure gives you a firm ceiling before you start negotiating.

Expert tips

Work out the maximum refund before loss first, then offer well below it — that keeps room to move if the buyer pushes back.
Percentage-off offers (10%, 20%) feel fair but ignore your margin. Check the dollar figure against profit before you send it.
Remember platform fees were charged on the original order revenue, so a partial refund rarely refunds a matching share of fees.
Only count recovery value when the item actually comes back to you — if the buyer keeps it, recovery is zero.

How to interpret your results

Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.

Common mistakes

Offering a percentage off the order total without checking profit first.
Forgetting that platform fees are charged on the original revenue, not the reduced amount.
Counting recovery value when the customer keeps the item.
