The arithmetic
Spendable Ducats = max(0, balance minus reserve). Whole items affordable = floor(spendable divided by unit price).

A budget, not a prediction
The calculation does not estimate digging speed, item values, pet bonuses, bone probabilities or time to earn the shortfall.
Using the Ducat calculator
Does it know current equipment prices?
No. Enter the current price shown for the device you are considering. Blank defaults avoid assigning a guessed price to equipment.
Can I combine different item prices?
This form uses one unit price. Run separate calculations for different prices and update the remaining balance between purchases.
Does it tell me how long farming takes?
No. It calculates affordability and shortfall from your inputs. It does not predict junk values or a fixed income rate.
What does the reserve do?
It removes the Ducats you want to keep from the spending budget before calculating whole purchases. A reserve above the balance leaves no money available for this plan.
