The correct formula of breakeven
it’s probably how the real TP works. the reason is rounding – it always against your favor
buy for 4c is you pay 4c
sell for 5c is you pay 1c to list, then when it sells for 5c, 10% is taken out = rounded to 4c. that’s 3c return = 1c lost.
250 is trickier
sell for 250 × 5c = 62.5c cost to list, rounded to 63c. if all 250 sell at once, final value fee will be 250 × 5 × 0.1 = 125c. if they sell one at a time, final value fee will be 250 x round(5 × 0.1) = 250 × 1 = 250c. so if you sell 250 at 5c, the total fee will range from 188c to 313, making the return range from 937c to 1062c = -63c to 62c profit (when considering you bought it at 4c each)

wow, that blows my mind.
That means the tax is calculated per purchase from buyers, not when the money is collected. And that means especially in large volume, the profit calculated may not be as much as calculated depends on how large the buy orders are.
yes. but selling larger amounts will always be more profitable than smaller. the listing fee will be smaller, and it’s nearly guaranteed people won’t be buying them one at a time, though this depends on the item.
I usually don’t consciously factor this in. Only case I do is saving up several crafting materials (such as carrots) before selling. Like times when TP gives just a bit more profit than merchant (selling one at a time might give 1c profit, but 30 at a time would give 70c profit)
For most things, I will usually assume ~3c less profit than predicted due to this. It basically keeps me away from trying to flip things that sell for less than 10c.
