What does $2,800.00 a month of bassoon allowance mean?
It means $1,600.00 of recurring base allowance plus $1,200.00 of paid bassoon classes: 5 classes at $240.00 each. The base is 57.14% of the monthly total and the classes are the remaining 42.86%. Over 12 months that is $19,200.00 of base plus $14,400.00 of bassoon classes, $33,600.00 in all. If the base rises by $10.00 the month rises by $10.00 and the year by $120.00; if the per-class price rises by $10.00 the month rises by $40.00 and the year by $480.00, because the per-class price applies to all five classes.

Three things to check before you trust the number
First, the base must be the recurring monthly amount only: bassoon class dues, a class-fee share, an insurance share and reed, bocal and bell upkeep that repeat every month. A one-off purchase — a new reed bought once — is not a monthly cost, and spreading it across the base inflates every month that follows. Second, count only classes you pay for individually; a class covered by a class package costs $0.00 extra and must not be counted, or the total counts it twice. Third, keep the per-class price complete: the class charge plus any booking fee and class entry you always pay, because pricing only the class charge understates every class. Bassoon itself is hands-on — note by note — so its costs are simple too: reed, bocal and bell, with the base itself carrying just over half the money.
Worked example
Base $1,600.00, 5 bassoon classes, $240.00 per class. Classes total: 5 × $240.00 = $1,200.00. Monthly total: $1,600.00 + $1,200.00 = $2,800.00. Yearly total: $2,800.00 × 12 = $33,600.00, split as $19,200.00 base and $14,400.00 classes. Add a sixth class and the month becomes $3,040.00 and the year $36,480.00; drop to four classes and the month becomes $2,560.00 and the year $30,720.00. Raise the base to $1,625.00 and the month becomes $2,825.00 and the year $33,900.00. Lower the per-class price to $230.00 and the month becomes $2,750.00 and the year $33,000.00. Raise it to $250.00 and the month becomes $2,850.00 and the year $34,200.00.
Every branch, checked
A $1,610 base with the same bassoon classes and per-class amount gives $2,810.00 a month and $33,720.00 a year. A $230.00 per-class price is the lower branch; at $230.00 per bassoon class with the same base and bassoon classes the figures are $2,750.00 a month and $33,000.00 a year. Six bassoon classes with the same base and per-class amount give $3,040.00 a month and $36,480.00 a year. Four bassoon classes with the same base and per-class amount give $2,560.00 a month and $30,720.00 a year. Each branch changes exactly one input, so the difference from $2,800.00 isolates that input.
The reverses, worked backwards
The base behind $2,800.00 a month is $1,600.00: at $1,590.00 the figures are $2,790.00 a month and $33,480.00 a year, and at $1,610.00 they are $2,810.00 a month and $33,720.00 a year — a $10.00 step moves the month by $10.00. The per-class amount behind $2,800.00 a month is $240.00: at $230.00 the figures are $2,750.00 a month and $33,000.00 a year, and at $250.00 they are $2,850.00 a month and $34,200.00 a year — a $10.00 step moves the month by $50.00, because it applies to all five classes. The bassoon classes behind $2,800.00 a month are 5: at 3 classes the figures are $2,560.00 a month and $30,720.00 a year, and at 5 classes they are $3,040.00 a month and $36,480.00 a year.
What the defaults assume
The defaults assume a steady $1,600.00 base, 5 paid bassoon classes a month and a steady $240.00 per-class price, all year. Real bassoon practice clusters around busy class 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 classes is the honest edge: $1,600.00 a month and $19,200.00 a year, the base alone. Negative inputs are rejected, and a per-class price of $0.00 simply means every class is covered by the base or a package.
Who uses this
A bassoon practitioner pricing a monthly allowance: the $2,800.00 monthly total is the figure to budget, and the $33,600.00 yearly total is the reason to check the per-class price. A class leader setting membership tiers: the base line prices the recurring share, and the classes line prices the paid guided classes on top of it. A parent planning a family practice budget: the classes line shows exactly how much each extra paid class per month is worth over a year. A household cutting leisure spending without giving up bassoon: 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-class price that omits the booking fee, or a class count that includes covered classes will each move the answer by exactly the amount of the error, every month. The model does not include travel to the class, craft 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: bassoon class dues, a class-fee share, an insurance share and reed, bocal and bell upkeep. Paid classes are a separate line, and one-off purchases belong in the month they are charged, not spread across the base.
What if my classes are covered by a class package?
Enter 0 classes, or a $0.00 per-class price, and the total is the base alone: $1,600.00 a month and $19,200.00 a year on the example figures. A covered class 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 classes line from the monthly total to recover the base; subtract the base and divide by the classes to recover the per-class price; subtract the base and divide by the per-class price to recover the classes. 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-class 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 class count is right — 60 classes a year is 60 classes a year however they are spread.
