Refund impact measures how much revenue and profit are reversed by customer refunds. Even a modest refund rate can materially reduce margin after operating costs.
Use refund impact together with return rate to separate product return problems from payment or customer service refund problems.
If revenue is $100,000 and refunds are $4,000, refund rate is 4%. At 45% margin plus $600 extra costs, profit loss is $2,400.
A healthy refund rate is usually low enough that gross margin and advertising payback remain stable after refund costs.
Refunds reduce profit by reversing gross profit and adding costs such as payment fees, shipping, support, and restocking.
Store credit can protect cash flow and future revenue, but refund policies must remain fair and legally compliant.
Reduce refund requests by improving product accuracy, shipping reliability, customer support, and pre-purchase education.
