Snorkeling Allowance Calculator: $270 a Month, $3,240
On the defaults — a $90.00 monthly base allowance plus 3 snorkeling sessions a month at $60.00 each — your snorkeling allowance totals $270.00 a month and $3,240.00 for the year. This is the SNORKELING version — a monthly base for snorkeling extras plus paid snorkeling sessions priced monthly — the climbing-allowance-calculator page is the CLIMBING version, the skateboarding-allowance-calculator page is the SKATEBOARDING version, the sports-allowance-calculator page is the SPORTS version, and the how-to-calculate-snorkeling-allowance guide is the METHOD version — the same $90.00 base plus 3 snorkeling sessions at $60.00 worked step by step.
What does $270.00 a month of snorkeling allowance mean?
It means $90.00 of recurring base allowance plus $180.00 of paid snorkeling sessions: 3 sessions at $60.00 each. The base is 33.33% of the monthly total, and the snorkeling sessions are the remaining 66.67%. Over 12 months that is $1,080.00 of base plus $2,160.00 of snorkeling sessions, $3,240.00 in all. If the base rises by $10.00, the monthly total rises by exactly $10.00; if one snorkeling session is added at $60.00, the monthly total rises by $60.00.

Three things to check before you trust the number
First, the base must be genuinely recurring: mask upkeep, fin straps, snorkel parts, defogger and small extras that repeat every month. A single new wetsuit or full gear set bought once is not base, and spreading it across the base inflates every month that follows. Second, count only paid snorkeling sessions: reef trips bundled into a club membership or already covered by the base allowance cost $0.00 extra and must not be entered, or the total counts them twice. Third, the per-session price must be everything that session costs you — boat fee plus any session-only guide fee or reef entry charge — not the boat fee on its own, or the year total quietly understates what snorkeling really costs.
Worked example
Base $90.00, 3 snorkeling sessions, $60.00 per snorkeling session. Snorkeling sessions total: 3 × $60.00 = $180.00. Monthly total: $90.00 + $180.00 = $270.00. Yearly total: $270.00 × 12 = $3,240.00, split as $1,080.00 base and $2,160.00 sessions. Add a fourth session and the month becomes $330.00; drop to two sessions and it becomes $210.00. The base share rises as sessions fall, because the base stays fixed while the sessions line shrinks.
Every branch, checked
A $110.00 base with the same snorkeling sessions and per-session amount gives $290.00 a month and $3,480.00 a year. A $50.00 per-session amount with the same base and snorkeling sessions gives $240.00 a month and $2,880.00 a year. Two snorkeling sessions with the same base and per-session amount give $210.00 a month and $2,520.00 a year. Four snorkeling sessions with the same base and per-session amount give $330.00 a month and $3,960.00 a year. Each branch changes exactly one input, so the difference from $270.00 isolates that input.
The reverses, worked backwards
The base behind $270.00 a month is $90.00: at $80.00 the figures are $260.00 a month and $3,120.00 a year, and at $100.00 they are $280.00 a month and $3,360.00 a year — a $10.00 step moves the month by $10.00. The per-session amount behind $270.00 a month is $60.00: at $50.00 the figures are $240.00 a month and $2,880.00 a year, and at $70.00 they are $300.00 a month and $3,600.00 a year — a $10.00 step moves the month by $30.00, because it applies to all three sessions. The snorkeling sessions behind $270.00 a month are 3: at 2 sessions the figures are $210.00 a month and $2,520.00 a year, and at 4 sessions they are $330.00 a month and $3,960.00 a year — one session either way moves the month by $60.00.
What the defaults assume
The defaults assume a flat $90.00 base every month of the year, 3 paid snorkeling sessions every month, and a constant $60.00 per snorkeling session. Real snorkeling runs in waves: a holiday month may hold 5 sessions and a winter 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 snorkeling sessions is the honest edge: $90.00 a month and $1,080.00 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 three-times-a-month snorkeler budgeting the year: the base covers mask upkeep, fin straps and defogger, the sessions line prices the paid boat trips and guided reef days, and the year total is the annual budget. A dive-club member comparing plans: the base is the shared club allowance and the per-session price is the boat or guided-day rate. A parent pricing a child snorkeling program: the base is the monthly club fee and the snorkeling sessions are the paid reef days. A benefits manager comparing sport allowances: the same base-plus-sessions shape prices snorkeling 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 guide fees will each move the answer by exactly the amount of the error, every month. The model does not include travel, accommodation, wetsuits bought as a block, camera gear, 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 mask upkeep, fin straps, snorkel replacement parts, defogger and small snorkeling extras: the figure set each month. Paid snorkeling sessions are not part of the base — they have their own line — and one-off charges such as a new wetsuit belong in the month they are charged, not spread across the base.
What if my snorkeling sessions are covered by the base allowance?
Enter 0 snorkeling sessions, or a $0.00 cost per snorkeling session, and the total is the base alone: $90.00 a month and $1,080.00 over 12 months on these defaults. A covered snorkeling 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: 3 sessions a month here means 36 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 snorkeling year.
Does the base include a dive-club membership?
No. A dive-club 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 snorkeling session move the month by $60.00?
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 snorkeling allowance my employer pays?
Yes, as a pricing check: enter the employer base and per-session rate and compare the year total with the employer cap. The calculator prices whatever figures you enter; it does not check any employer rules.
