Rafting Allowance Calculator: $245/mo, $2,940 a Year
On the defaults — a $95.00 monthly base allowance plus 2 rafting sessions a month at $75.00 each — your rafting allowance totals $245.00 a month and $2,940.00 for the year. This is the RAFTING version — a monthly base for rafting extras plus paid rafting sessions priced monthly — the kayaking-allowance-calculator page is the KAYAKING version, the rowing-allowance-calculator page is the ROWING version, the fishing-allowance-calculator page is the FISHING version, and the how-to-calculate-rafting-allowance guide is the METHOD version — the same $95.00 base plus 2 rafting sessions at $75.00 worked step by step.
What does $245.00 a month of rafting allowance mean?
It means $95.00 of recurring base allowance plus $150.00 of paid rafting sessions: 2 sessions at $75.00 each. The base is 38.78% of the monthly total, and the rafting sessions are the remaining 61.22%. Over 12 months that is $1,140.00 of base plus $1,800.00 of rafting sessions, $2,940.00 in all. If the base rises by $20.00, the monthly total rises by exactly $20.00; if one rafting session is added at $75.00, the monthly total rises by $75.00.

Three things to check before you trust the number
First, the base must be genuinely recurring: paddle grip checks, helmet strap replacement, dry-bag patches and small extras that repeat every month. A single new raft bought once is not base, and spreading it across the base inflates every month that follows. Second, count only paid rafting sessions: days already covered by a club membership or included in 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 — raft hire plus river access, and any session-only guide fee or water insurance charge — not the hire charge on its own, or the year total quietly understates what rafting really costs.
Worked example
Base $95.00, 2 rafting sessions, $75.00 per rafting session. Rafting sessions total: 2 × $75.00 = $150.00. Monthly total: $95.00 + $150.00 = $245.00. Yearly total: $245.00 × 12 = $2,940.00, split as $1,140.00 base and $1,800.00 sessions. Add a third session and the month becomes $320.00; drop to one session and it becomes $170.00. The base share rises as sessions fall, because the base stays fixed while the sessions line shrinks.
Every branch, checked
A $115.00 base with the same rafting sessions and per-session amount gives $265.00 a month and $3,180.00 a year. A $65.00 per-session amount with the same base and rafting sessions gives $225.00 a month and $2,700.00 a year. Three rafting sessions with the same base and per-session amount give $320.00 a month and $3,840.00 a year. One rafting session with the same base and per-session amount gives $170.00 a month and $2,040.00 a year. Each branch changes exactly one input, so the difference from $245.00 isolates that input.
The reverses, worked backwards
The base behind $245.00 a month is $95.00: at $85.00 the figures are $235.00 a month and $2,820.00 a year, and at $105.00 they are $255.00 a month and $3,060.00 a year — a $10.00 step moves the month by $10.00. The per-session amount behind $245.00 a month is $75.00: at $65.00 the figures are $225.00 a month and $2,700.00 a year, and at $85.00 they are $265.00 a month and $3,180.00 a year — a $10.00 step moves the month by $20.00, because it applies to both sessions. The rafting sessions behind $245.00 a month are 2: at 1 session the figures are $170.00 a month and $2,040.00 a year, and at 3 sessions they are $320.00 a month and $3,840.00 a year — one session either way moves the month by $75.00.
What the defaults assume
The defaults assume a flat $95.00 base every month of the year, 2 paid rafting sessions every month, and a constant $75.00 per rafting session. Real rafting runs on river levels: a high-water month may hold 4 sessions and a low-water 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 rafting sessions is the honest edge: $95.00 a month and $1,140.00 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 rafter budgeting the year: the base covers paddle checks and dry-bag patches, the sessions line prices the paid river days and guiding, and the year total is the annual budget. A club member comparing plans: the base is the monthly upkeep allowance and the per-session price is the hire or guide rate for days beyond the membership. A parent pricing a teen rafting program: the base is the monthly club fee and the rafting sessions are the paid river days. A benefits manager comparing sport allowances: the same base-plus-sessions shape prices rafting next to kayaking, rowing 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 river access or guide charges will each move the answer by exactly the amount of the error, every month. The model does not include travel, accommodation, rafts 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 paddle grip checks, helmet strap replacement, dry-bag patches and small rafting extras: the figure set each month. Paid rafting sessions are not part of the base — they have their own line — and one-off charges such as a new raft belong in the month they are charged, not spread across the base.
What if my rafting sessions are covered by a club membership?
Enter 0 rafting sessions, or a $0.00 cost per rafting session, and the total is the base alone: $95.00 a month and $1,140.00 over 12 months on these defaults. A covered rafting 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 highest-water 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 highest-water month only when you are pricing that month itself, and say so, or the year total will overstate the season.
Does the base include a club membership?
No. A 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 rafting session move the month by $75.00?
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 rafting 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.
