How Income Is Calculated

"Silver per day" is the single most abused number in BDO planning, so here is the whole chain with nothing hidden.

It is raw selling, not crafting

Every figure in this tool is the market value of what workers deposit in storage, sold as-is. No cooking, no alchemy, no processing, no imperial crates, no trade routes. Those can all beat raw selling, sometimes by a lot, and none of them are modelled here.

So read the headline as a floor on what this node set is worth, not a ceiling. Turning raw drops into something better is upside this tool does not claim.

The chain

1. A worker finishes a cycle. How often depends on its workspeed, the distance from its lodging to the node, and the node's own cycle time. The solver already accounts for this - cycles/day in the worker table is the result. 2. A cycle drops items. Quantities per cycle come from Workerman's plantzone_drops.json, scaled by the worker's luck for the drops luck affects. Multiply out and you get qty/day per item, which is what the item table shows. 3. Each item gets a price. In this order, exactly as build_prices.py does it:

• the raw market price, pre-tax;
• or a fixed vendor price, if the item is one of the 45 that sell to an NPC instead - these are never taxed;
• market-priced items are then multiplied by the sale tax, ×0.845 here;
• sacks last. 5 items are containers whose value is the sum of their contents at the prices just computed. 4. Sum it. 681.7m/day gross. 5. Subtract food. 815 units a day at the untaxed market price, 5.3m - about 0.8% of gross. Worker upkeep is close to a rounding error at this scale.

Why the page recomputes instead of storing silver

The dashboard carries the price model - raw prices, the vendor list, the sack recipes - not baked silver figures. Every number is derived in the browser. That is why changing the tax rate, pulling a live market, or switching to median pricing all re-price the entire page instantly and identically: they are the same operation with a different input.

Exposure is measured, not assumed

You cannot work out how much a price matters by summing that item's own sales. Sacks are priced off other items, so value arrives indirectly.

Some Archaeologist's Sack is the case that makes the point: it is untaxed and sells to an NPC, so it looks like fixed-price vendor income - but its price is derived from Trace of Nature, so it moves with the market anyway. Treating it as price-immune overstated the plan's safety by a factor of twenty.

So exposure is measured by nudging each price 1% and reading what the whole plan does:

What is deliberately not in the number

• Processing, cooking, alchemy, imperial delivery, trade runs. Upside, unmodelled.
• Your own time. The plan is chosen to minimise fiddling, but collection trips are real and are not priced.
• Storage. 71 item types against 16 warehouse slots, or 32 with a Value Pack. Past that you rent space with CP this budget never counted.
• Whether the market will absorb it. Turn on order-book pricing in the drawer for the honest version - see Volatility and Price Bands.
