How to Calculate Skateboarding Allowance: Step-by-Step

Price the base, count the sessions, add the lines, multiply by 12. This guide works the $80.00 base plus 3 skateboarding sessions at $50.00 example step by step — $230.00 a month, $2,760.00 a year — and shows how to check any skateboarding allowance backwards. For the interactive version, use the skateboarding-allowance-calculator.

Skateboarding allowance in one line

A skateboarding allowance is simple: a monthly base amount, plus the number of paid skateboarding sessions multiplied by the price of one skateboarding session, all multiplied by twelve for the year. Base plus skateboarding sessions times price, then times twelve. The worked example throughout is a $80.00 monthly base, 3 skateboarding sessions a month, and $50.00 per skateboarding session, which totals $230.00 a month and $2,760.00 a year.

Step 1: Price the monthly base allowance

The base allowance is the flat amount set each month for skateboarding extras, before any paid skateboarding sessions. Grip tape, bearings, bushings, hardware, wheel wear and small recurring extras belong here. A new deck or set of trucks, a skatepark membership and travel do not: a membership paid yearly is a lump sum, decks and trucks are one-off purchases, and travel varies by session and by venue. If your park or employer sets the base, use their figure exactly. If you set it yourself, look at last season: add up a typical month of grip tape, bearings, bushings, hardware, wheel wear and small extras, and use that monthly average. Check that your base is monthly before multiplying by twelve.

Step 2: Count only the paid skateboarding sessions

Session-counting is the heart of this step: count the skateboarding sessions you pay for individually each month, and nothing else. Sessions covered by a skatepark membership or already included in the base allowance cost $0.00 extra, and counting them inflates the total by a full per-session price each time. A month with 3 paid sessions and 8 covered park visits is a 3-session month for this calculation, not an 11-session month. If your schedule varies, use the average month across the season: 36 paid sessions over a 12-month year is 3 a month, even if one month held 5 and another held only 1.

Step 3: Add the lines and multiply by 12

Multiply the paid sessions by the per-session price — 3 × $50.00 = $150.00 — then add the base: $80.00 + $150.00 = $230.00 a month. Multiply by 12 for the year: $230.00 × 12 = $2,760.00, split as $960.00 of base ($80.00 × 12) and $1,800.00 of sessions ($150.00 × 12). Keep the two lines separate all the way through: the split is what lets you check the result, compare seasons, and see which line is driving the total. A single combined figure hides all of that, and it hides the one error most people make, which is a sessions line that counts covered visits as paid ones.

Step 4: Check the result backwards

Work backwards from the monthly total to prove each input. The base behind $230.00 a month is $230.00 − $150.00 = $80.00; move it to $70.00 and the month falls to $220.00, move it to $90.00 and the month rises to $240.00. The per-session price behind $230.00 a month is ($230.00 − $80.00) ÷ 3 = $50.00; at $40.00 the month is $200.00, at $60.00 it is $260.00. The sessions behind $230.00 a month are ($230.00 − $80.00) ÷ $50.00 = 3; at 2 sessions the month is $180.00, at 4 sessions it is $280.00. If any backward check lands somewhere you did not expect, the input behind it is the one to re-examine.

A season in numbers

Skateboarding rarely runs flat across the year, so test the method on a short season before trusting the yearly figure. Take four months: a contest month with 5 sessions, two ordinary months with 3 sessions each, and a rainy month with 1 session. The months cost $330.00, $230.00, $230.00 and $130.00, which add to $920.00 over the four months — an average of $230.00 a month, exactly the worked example. That average is the honest input for the year total: pricing the contest month as if it were every month would turn the season into $1,320.00 for those four months alone, while pricing the rainy month as typical would understate it at $520.00.

Common mistakes

The most common mistake is counting covered sessions as paid ones: a park visit already inside the membership is not a $50.00 session, and adding it double-counts the membership. The second is putting one-off kit into the base: a new deck belongs in the month it is bought, not spread across every month of the year. The third is entering the busiest month as if it were every month: a 5-session contest month priced as the average turns a $2,760.00 year into a $3,960.00 year on paper. The fourth is a per-session price that omits coaching fees: park entry alone is not the session cost when a coach is also paid, and the missing coaching fee repeats every session, so a $10.00 omission becomes $360.00 over a 36-session year.

Worked example, start to finish

Base $80.00, 3 skateboarding sessions, $50.00 per skateboarding session. Sessions line: 3 × $50.00 = $150.00. Monthly total: $80.00 + $150.00 = $230.00. Yearly total: $230.00 × 12 = $2,760.00 — $960.00 base plus $1,800.00 sessions. Check it backwards: $230.00 − $150.00 = $80.00 base, ($230.00 − $80.00) ÷ 3 = $50.00 per session, ($230.00 − $80.00) ÷ $50.00 = 3 sessions. Add a fourth session and the month becomes $280.00; drop to two sessions and it becomes $180.00. The base share is $80.00 ÷ $230.00 = 34.78% of the month, and it rises whenever sessions fall, because the base stays fixed while the sessions line shrinks.

What changes the answer most

Sessions move this allowance more than anything else, because each one carries a full per-session price: a $10.00 change in the per-session price moves the month by $30.00, while the same $10.00 change in the base moves it by only $10.00. A miscounted session is a $50.00 monthly error, or $600.00 over the year. Check the sessions first when an allowance feels wrong.

Frequently asked questions

What counts as the monthly base allowance?

The recurring monthly amount for grip tape, bearings, bushings, hardware, wheel wear and small skateboarding extras. Paid skateboarding sessions have their own line, and one-off purchases such as a new deck belong in the month they are charged.

What if all my skateboarding sessions are covered by my membership?

Enter 0 paid sessions: the total is the base alone, $80.00 a month and $960.00 a year on the worked example. A covered session costs $0.00 extra by definition, and the honest edge is the base on its own.

Should I use my average month or my busiest month?

The average month, if the year total is what matters: 3 sessions a month means 36 sessions a year. Price the busiest month only when you are budgeting that month itself, and say so, or the year total will overstate the season.

Why does the base share change when sessions change?

Because the base is fixed and the sessions line moves: at 2 sessions the base is $80.00 of $180.00, or 44.44%, while at 4 sessions it is $80.00 of $280.00, or 28.57%. The base never changed — only its share of a moving total did.
