1. Source and version
The calculator's crop names, seasons, growth time, regrowth interval, yield, seed cost, and sale values come from the Official Moonlight Peaks Wiki crop table. The current snapshot is revision 12780, timestamped2026-07-28T02:11:33Z.
The dataset is attributed under CC BY-SA 4.0. The game's official Steam pageconfirms the developer, publishers, release date, and that crops and magic are core game systems.
2. Single-harvest crops
For a crop that must be replanted, the calculator uses:
Harvests per plot = floor(days remaining ÷ growth days)
Net profit = (harvests × yield × sale price × plots) − (harvests × seed cost × plots)
Example: Carrot takes 6 days, yields 1, sells for 160 regular coins, and costs 80 per seed. In 28 days it fits four complete cycles. One plot earns 640 gross, spends 320 on seeds, and nets 320 coins.
3. Regrowing crops
A regrowing crop buys one seed pack per plot. The first harvest arrives after the full growth time; later harvests use the regrowth interval.
Harvests per plot = 1 + floor((days remaining − growth days) ÷ regrowth days)
Seed packs per plot = 1, but only when the first harvest can finish
Example: Blueberry takes 9 days, then regrows every 3 days. In 28 days it produces on days 9, 12, 15, 18, 21, 24, and 27: seven harvests from one seed pack.
4. Quality prices and missing values
Regular, 1-star, and 2-star values are read independently. They are not generated with a multiplier. When the pinned source does not list a selected quality value, that crop is removed from that quality ranking and the interface shows a warning. This prevents a plausible-looking estimate from becoming false evidence.
5. Magic-crop constraints
Every magic crop requires Aquaflux. Some also need manual or material inputs. Drikker needs its cup filled; Gobbler consumes requested fish or critters; Mandrake outcomes depend on spacing; Wicca outcomes depend on a companion setup. The tool displays these notes but does not convert mana, fish, critters, or companion land into coin costs because the source does not provide a stable universal price for them.
6. Data conflicts and update policy
Post-launch guides can disagree. For example, some early tables list Gobbler's regular sale price as 550, while the current Official Wiki crop table and Gobbler item page list 500. The calculator pins the current official table value and publishes its revision number. It never silently averages conflicting values.
A future update should replace the snapshot only after checking the new source revision, rerunning formula tests, rebuilding every generated table, and reviewing visible ranking changes.
7. Deliberate exclusions
The current profit number does not include:
- processed outputs such as wine, juice, or jam;
- fertilizer, moon-phase effects, or probabilistic quality distribution;
- labor, mana, missed care, or travel time;
- feed-item opportunity cost or companion-crop land;
- cross-season survival assumptions.
These exclusions are not claims that the effects do not matter. They define a narrow, comparable question:what is the raw-sale net return if every listed harvest succeeds?
