A full inventory does not tell you what a farm session earned. In Knight Online, subtract the supplies you consumed and other session costs from the Noah you actually received. Keep unsold loot on a separate list: an asking price is not money in your wallet.

Keep a usable session log
Record the server, spot, gear and start and finish times. Include trips to town, resupply and PvP interruptions. Compare spots using the same time budget. Counting only the minutes spent killing mobs makes an interrupted route look better than it is.
| Entry | Treatment |
|---|---|
| Noah collected | Income |
| Loot already sold | Amount received after any deductions |
| Potions, arrows and scrolls consumed | Quantity used × unit cost |
| Repairs and other session charges | Expense |
| Unsold items | Separate inventory; no realized income yet |
A worked 90-minute example
Use these illustrative numbers: 12 million Noah collected, 8 million received from loot sales and 5 million spent on consumed supplies and repairs. Net income is 12 + 8 − 5 = 15 million Noah. Over 90 minutes, that is 15 × 60 / 90 = 10 million Noah per hour. These numbers are not measured earnings for a farming spot.
Avoid charging yourself twice
Supplies bought yesterday still have a cost when you use them today. Equally, do not charge an entire stockpile to one session if you only used part of it. When adding income entries, subtract expenses separately. When using a wallet balance difference, do not subtract repairs already paid from that wallet again; account for bank transfers too.
One lucky drop does not settle the comparison
Log several sessions under similar conditions. Keep ordinary runs and rare-drop runs visible instead of assuming the same valuable item will drop every hour. If you allocate Premium or timed-support costs, write down your allocation. The accounting method works for USKO and SteamKO without assuming their server rules or drops match.
