Frequently Asked Questions
How does the offer acceptance calculator work?
Enter your listing price, the offer received, your COGS, and platform fee rate. The calculator shows your net profit at the offered price, compares it to your target margin, and computes profit per day held. Add your average days-to-sell history and it factors in holding cost to determine whether accepting now beats waiting for a higher offer.
What does profit per day mean and why does it matter for resellers?
Profit per day is your net profit divided by days held. A $30 profit after 90 days ($0.33/day) is often worse than a $22 profit accepted today ($22/day if relisted immediately). High-volume resellers optimize profit per day, not absolute margin — accepting a slight discount for fast turnover frequently outperforms holding for a 20% higher offer that takes months to arrive.
When should I counter instead of accepting or rejecting an offer?
Counter when the gap between the offer and your minimum acceptable price is less than 15-20% and the item has not been held long. Counter at 5-10% below your list price as a flexibility signal. Reject outright when the offer falls below COGS plus fees. Accept immediately when the offered profit-per-day exceeds your average and you have faster-moving inventory waiting for that capital.
How do I factor in holding costs when deciding to accept an offer?
Holding costs include capital tied up in the item (opportunity cost), storage space, and monthly listing fees. The calculator uses an adjustable holding cost rate — typically 0.5-2% of item cost per month — to reduce the "wait" scenario's expected value. A $200 item held 60 extra days for $20 more rarely wins when that capital could fund two faster-turning flips.
Does the offer acceptance calculator work for eBay Best Offer and Poshmark?
Yes — enter the gross offer and select your platform to auto-apply the correct fee rate (eBay ~13.25%, Poshmark 20%). For eBay, Best Offer acceptance locks the sale immediately. On Poshmark, buyers must still complete checkout. For any platform not listed, enter the fee percentage manually and the tool calculates net payout and profit per day for the decision.
