Resale Profit Calculator (what you keep after fees & shipping when selling used items)

How it works

You keep = selling price − percentage fees (price × fee %) − fixed fee − shipping − packaging. Value kept = what you keep ÷ what you originally paid. Cost of owning it per month = (original price − what you keep) ÷ months used — the real monthly cost of having the item. The lowest sensible price is the one where fees and shipping take everything: (fixed fee + shipping + packaging) ÷ (1 − fee %).

FAQ

Should I offer free shipping?

Only if you add it to the price. Shipping you pay comes straight out of what you keep, which matters most on cheap items.

Why show cost per month?

It shows what using the item really cost you. Something bought for 300 and sold for 111 after 18 months cost about 10.50 a month.
