Bouldering Allowance Calculator: $185 a Month, $2,220 a Year
On the defaults — an $85.00 monthly base allowance plus 2 bouldering sessions a month at $50.00 each — your bouldering allowance totals $185.00 a month and $2,220.00 for the year. This is the BOULDERING version — a monthly base for bouldering extras plus paid bouldering sessions priced monthly — the climbing-allowance-calculator page is the CLIMBING version, the gym-allowance-calculator page is the GYM version, the sports-allowance-calculator page is the SPORTS version, and the how-to-calculate-bouldering-allowance guide is the METHOD version — the same $85.00 base plus 2 bouldering sessions at $50.00 worked step by step.
What does $185.00 a month of bouldering allowance mean?
It means $85.00 of recurring base allowance plus $100.00 of paid bouldering sessions: 2 sessions at $50.00 each. The base is 45.95% of the monthly total, and the bouldering sessions are the remaining 54.05%. Over 12 months that is $1,020.00 of base plus $1,200.00 of bouldering sessions, $2,220.00 in all. If the base rises by $10.00, the monthly total rises by exactly $10.00; if one bouldering session is added at $50.00, the monthly total rises by $50.00.

Three things to check before you trust the number
First, the base must be genuinely recurring: chalk, tape, shoe care, brush replacement and small extras that repeat every month. A single new pair of climbing shoes bought once is not base, and spreading it across the base inflates every month that follows. Second, count only paid bouldering sessions: gym time bundled into a membership or already covered by the base allowance costs $0.00 extra and must not be entered, or the total counts it twice. Third, the per-session price must be everything that session costs you — wall time plus any session-only coaching or clinic charge — not the wall fee on its own, or the year total quietly understates what bouldering really costs.
Worked example
Base $85.00, 2 bouldering sessions, $50.00 per bouldering session. Bouldering sessions total: 2 × $50.00 = $100.00. Monthly total: $85.00 + $100.00 = $185.00. Yearly total: $185.00 × 12 = $2,220.00, split as $1,020.00 base and $1,200.00 sessions. Add a third session and the month becomes $235.00; drop to one session and it becomes $135.00. The base share rises as sessions fall, because the base stays fixed while the sessions line shrinks.
Every branch, checked
A $105.00 base with the same bouldering sessions and per-session amount gives $205.00 a month and $2,460.00 a year. A $40.00 per-session amount with the same base and bouldering sessions gives $165.00 a month and $1,980.00 a year. One bouldering session with the same base and per-session amount gives $135.00 a month and $1,620.00 a year. Three bouldering sessions with the same base and per-session amount give $235.00 a month and $2,820.00 a year. Each branch changes exactly one input, so the difference from $185.00 isolates that input.
The reverses, worked backwards
The base behind $185.00 a month is $85.00: at $75.00 the figures are $175.00 a month and $2,100.00 a year, and at $95.00 they are $195.00 a month and $2,340.00 a year — a $10.00 step moves the month by $10.00. The per-session amount behind $185.00 a month is $50.00: at $40.00 the figures are $165.00 a month and $1,980.00 a year, and at $60.00 they are $205.00 a month and $2,460.00 a year — a $10.00 step moves the month by $20.00, because it applies to both sessions. The bouldering sessions behind $185.00 a month are 2: at 1 session the figures are $135.00 a month and $1,620.00 a year, and at 3 sessions they are $235.00 a month and $2,820.00 a year — one session either way moves the month by $50.00.
What the defaults assume
The defaults assume a flat $85.00 base every month of the year, 2 paid bouldering sessions every month, and a constant $50.00 per bouldering session. Real bouldering runs in waves: a trip month may hold 4 sessions and a rest month none, so the honest use is to enter the average month, or to run the calculator once per stretch of the year and add the stretches. Zero bouldering sessions is the honest edge: $85.00 a month and $1,020.00 a year, the base alone. Negative inputs are rejected — a base, a session count, or a per-session price below zero has no meaning here.
Who uses this
A twice-a-month boulderer budgeting the year: the base covers chalk, tape and shoe care, the sessions line prices the paid wall time, and the year total is the annual budget. A climbing-gym member comparing plans: the base is the shared gym allowance and the per-session price is the drop-in rate. A parent pricing a child’s bouldering program: the base is the monthly gym fee and the bouldering sessions are the paid climbing days. A benefits manager comparing sport allowances: the same base-plus-sessions shape prices bouldering next to climbing, gym and other sports on equal terms.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is in the inputs. A base that bundles one-off purchases, a session count that mixes covered and paid sessions, or a per-session price that omits coaching fees will each move the answer by exactly the amount of the error, every month. The model does not include travel, outdoor trip lodging, shoes bought as a block, competition and event entry fees, or employer reimbursement caps — price those separately, and re-check the allowance when the base or the per-session price changes.

Frequently asked questions
What counts as the monthly base allowance?
The recurring amount for chalk, tape, shoe care, brush replacement and small bouldering extras: the figure set each month. Paid bouldering sessions are not part of the base — they have their own line — and one-off charges such as new shoes belong in the month they are charged, not spread across the base.
What if my bouldering sessions are covered by the base allowance?
Enter 0 bouldering sessions, or a $0.00 cost per bouldering session, and the total is the base alone: $85.00 a month and $1,020.00 over 12 months on these defaults. A covered bouldering session makes its sessions line $0.00 by definition, and that is the honest edge, not a missing input.
Should I enter my average month or my busiest month?
The average month, if you want the year total to be right: 2 sessions a month here means 24 sessions a year. Enter the busiest month only when you are pricing that month itself, and say so, or the year total will overstate the climbing year.
Does the base include a gym membership?
No. A gym membership paid yearly is a lump sum, not a monthly base. Either leave it out and price paid sessions only, or spread it yourself across the months it covers and add it to the base — but never do both, or the membership is counted twice.
Why does one extra bouldering session move the month by $50.00?
Because the per-session price applies once per session: one more session adds exactly one per-session charge. The base does not change when sessions change, which is why the sessions line, not the base, carries the seasonal swing.
Can I use this for a bouldering allowance my employer pays?
Yes, as a pricing check: enter the employer’s base and per-session rate and compare the year total with the employer’s cap. The calculator prices whatever figures you enter; it does not check any employer’s rules.
