What does $930.00 a month of watercolor allowance mean?
It means $410.00 of recurring base allowance plus $520.00 of paid watercolor workshops: 4 workshops at $130.00 each. The base is 44.09% of the monthly total and the workshops are the remaining 55.91%. Over 12 months that is $4,920.00 of base plus $6,240.00 of watercolor workshops, $11,160.00 in all. If the base rises by $10.00 the month rises by $10.00 and the year by $130.00; if the per-workshop price rises by $10.00 the month rises by $40.00 and the year by $480.00, because the per-workshop price applies to all four workshops.

Three things to check before you trust the number
First, the base must be the recurring monthly amount only: watercolor workshop dues, a workshop-fee share, an insurance share and watercolor paint, brush and paper upkeep that repeat every month. A one-off purchase — a new paint set bought once — is not a monthly cost, and spreading it across the base inflates every month that follows. Second, count only workshops you pay for individually; a workshop covered by a workshop package costs $0.00 extra and must not be counted, or the total counts it twice. Third, keep the per-workshop price complete: the workshop charge plus any booking fee and workshop entry you always pay, because pricing only the workshop charge understates every workshop. Watercolor itself is simple — paint each wash layer by layer — so its costs are simple too: paints, brushes and paper, with the guided workshops themselves carrying more than half the money.
Worked example
Base $410.00, 5 watercolor workshops, $130.00 per class. Classes total: 4 × $130.00 = $520.00. Monthly total: $410.00 + $520.00 = $930.00. Yearly total: $930.00 × 12 = $11,160.00, split as $4,920.00 base and $6,240.00 workshops. Add a fifth workshop and the month becomes $1,060.00 and the year $12,720.00; drop to three workshops and the month becomes $800.00 and the year $9,600.00. Raise the base to $435.00 and the month becomes $955.00 and the year $11,460.00. Lower the per-workshop price to $120.00 and the month becomes $890.00 and the year $10,680.00. Raise it to $140.00 and the month becomes $970.00 and the year $11,640.00.
Every branch, checked
A $420 base with the same watercolor workshops and per-workshop amount gives $940.00 a month and $11,280.00 a year. A $120.00 per-workshop price is the lower branch; at $120.00 per watercolor workshop with the same base and watercolor workshops the figures are $890.00 a month and $10,680.00 a year. Five watercolor workshops with the same base and per-workshop amount give $1,060.00 a month and $12,720.00 a year. Three watercolor workshops with the same base and per-workshop amount give $800.00 a month and $9,600.00 a year. Each branch changes exactly one input, so the difference from $930.00 isolates that input.
The reverses, worked backwards
The base behind $930.00 a month is $410.00: at $400.00 the figures are $920.00 a month and $11,040.00 a year, and at $420.00 they are $940.00 a month and $11,280.00 a year — a $10.00 step moves the month by $10.00. The per-workshop amount behind $930.00 a month is $130.00: at $120.00 the figures are $890.00 a month and $10,680.00 a year, and at $140.00 they are $970.00 a month and $11,640.00 a year — a $10.00 step moves the month by $40.00, because it applies to all four workshops. The watercolor workshops behind $930.00 a month are 4: at 3 workshops the figures are $800.00 a month and $9,600.00 a year, and at 5 workshops they are $1,060.00 a month and $12,720.00 a year.
What the defaults assume
The defaults assume a steady $410.00 base, 4 paid watercolor workshops a month and a steady $130.00 per-workshop price, all year. Real watercolor practice clusters around busy workshop months, so the honest use is to enter your average month, or to run the calculator once per stretch of the year and add the stretches. Zero workshops is the honest edge: $410.00 a month and $4,920.00 a year, the base alone. Negative inputs are rejected, and a per-workshop price of $0.00 simply means every workshop is covered by the base or a package.
Who uses this
A watercolor practitioner pricing a monthly allowance: the $930.00 monthly total is the figure to budget, and the $11,160.00 yearly total is the reason to check the per-workshop price. A workshop leader setting membership tiers: the base line prices the recurring share, and the workshops line prices the paid guided workshops on top of it. A parent planning a family practice budget: the workshops line shows exactly how much each extra paid workshop per month is worth over a year. A household cutting leisure spending without giving up watercolor: the branches show which input moves the total most.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is in the inputs. A base that hides a one-off purchase, a per-workshop price that omits the booking fee, or a workshop count that includes covered workshops will each move the answer by exactly the amount of the error, every month. The model does not include travel to the workshop, art fairs, or books — price those separately, and re-check the allowance when class dues or class prices change.

Frequently asked questions
What counts in the monthly base allowance?
Everything that repeats monthly: watercolor workshop dues, a workshop-fee share, an insurance share and watercolor paint, brush and paper upkeep. Paid workshops are a separate line, and one-off purchases belong in the month they are charged, not spread across the base.
What if my workshops are covered by a workshop package?
Enter 0 workshops, or a $0.00 per-workshop price, and the total is the base alone: $410.00 a month and $4,920.00 a year on the example figures. A covered workshop costs $0.00 extra by definition.
Should I use my average month or my busiest month?
The average month, if you want the year total to be right. Use the busiest month only when pricing that month itself, and say so, or the year total will overstate the season.
How do I check my answer backwards?
Subtract the workshops line from the monthly total to recover the base; subtract the base and divide by the workshops to recover the per-workshop price; subtract the base and divide by the per-workshop price to recover the workshops. If any recovery misses, an input is wrong.
Does the calculator handle employer-paid allowances?
Yes, as a pricing check: enter the employer base and per-workshop rate and compare the year total with the employer cap. It prices whatever figures you enter; it does not check any employer rules.
What if I practise more in some months than others?
Use the average month, or run the calculator once per stretch of the year and add the stretches. Both methods agree when the workshop count is right — 48 workshops a year is 48 workshops a year however they are spread.
