Premium Payback Calculator
How many days of farming to earn back the coin you paid for premium? Enter the premium price, your daily farm hours and hourly net income — it works over 30 days.
Payback time: how many days it takes to earn the premium cost back at your current farm pace.
30-day net result: answers whether the premium pays for itself by month end and whether there's profit on top.
Required target: if you fall short, it also says how many hours a day or how much coin an hour you'd need.
| Daily play | Daily net income | Payback time | 30-day net |

The formula is simple: premium cost ÷ daily net income = payback days. Daily net income is your daily farm hours times your hourly net income. The period is always judged over 30 days.
What premium brings depends on your character and what you do. On a farm character the drop and Noah boost goes straight to income; on a pure PK character the value of premium is in NP and comfort, not measurable in coin. This tool only counts income measurable in coin.
You should also weigh the market value of the gifts that come with premium — Trina, bonus KC, hammer — they're not counted here, so the real payback can be a bit shorter than the number shown.
- Measure hourly net income in the same zone at the same hour. Crowds and spawn luck skew the result.
- Measure at least 1 hour — a 15-minute sample is too exposed to luck.
- Value drops at market price, not NPC price.
- Subtract expenses like pots, scrolls and repairs; the number you enter should be net.
