One shared inventory
Every crop unit can enter only one route. Keg, Jar, and Dehydrator recommendations cannot double-count the same stack.
About ValleyMath
A small tool for a crowded shed
ValleyMath is an independent, fan-made planning site for players who have more crops than machines and want to know what to load next.
Last updated August 26, 2026Why this site exists
Stardew Valley already has good references for item prices and machine recipes. The harder late-game problem is practical: crops, brews, mushrooms, Honey, and Roe arrive in different batches, every machine is limited, and a high-value recipe can occupy capacity that another stack needs. A price table does not tell you what to load this morning.
ValleyMath combines inventory, raw-sale opportunity cost, machine counts, processing cycles, arrival dates, and a deadline. It returns an allocation and a morning action list; it does not claim that one machine is always best.
What makes the planner different
Finite machine time
Each job occupies a real machine slot until its morning collection day, so the plan respects the workshop you own.
Transparent opportunity cost
Input quality and profession affect the value sacrificed by processing. Gross revenue is never presented as if it were extra profit.
Independent and deliberately lightweight
The core planner runs inside the browser and does not require an account. Plans are stored on the player's own device. The interface uses original typography, color, and CSS shapes; it does not reuse official game artwork or present itself as an official product.
ValleyMath is not affiliated with or endorsed by ConcernedApe. Game names are used only to identify the rules the calculator models. Calculation scope and known limitations are published on the methodology page.
How the site may support itself
ValleyMath is intended to remain free. Display advertising may be added after the planner has stable usage and its calculations have been validated. Ads will not be placed inside inventory controls, disguised as navigation, or allowed to cover the plan. Any future ad and consent behavior will be disclosed in the privacy policy.
