Mahjong Allowance Calculator: $450/mo, $5,400 a Year
On the defaults — a $230.00 monthly base allowance plus 2 mahjong matches a month at $110.00 each — your mahjong allowance totals $450.00 a month and $5,400.00 for the year. This is the MAHJONG version — a monthly base for mahjong club dues and set upkeep plus paid mahjong matches priced monthly — the backgammon-allowance-calculator page is the BACKGAMMON version, the checkers-allowance-calculator page is the CHECKERS version, and the how-to-calculate-mahjong-allowance guide is the METHOD version — the same $230.00 base plus 2 mahjong matches at $110.00 worked step by step.
What does $450.00 a month of mahjong allowance mean?
It means $230.00 of recurring base allowance plus $220.00 of paid mahjong matches: 2 matches at $110.00 each. The base is 51.11% of the monthly total, and the mahjong matches are the remaining 48.89%. Over 12 months that is $2,760.00 of base plus $2,640.00 of mahjong matches, $5,400.00 in all. If the base rises by $10.00, the monthly total rises by exactly $10.00; if one mahjong match is added at $110.00, the monthly total rises by $110.00.

Three things to check before you trust the number
First, the base must be genuinely recurring: club dues, a league fee, an insurance share and mahjong set and table upkeep that repeat every month. A mahjong set bought once is not base, and spreading its price across the base inflates every month that follows. Second, count only paid mahjong matches: matches already covered by a club package or included in the base allowance cost $0.00 extra and must not be entered, or the total counts them twice. Third, the per-match price must be everything that match costs you — the match itself plus any scoring fee and tournament entry you always pay — not the match alone, or the year total quietly understates what mahjong really costs.
Worked example
Base $230.00, 2 mahjong matches, $110.00 per mahjong match. Mahjong matches total: 2 × $110.00 = $220.00. Monthly total: $230.00 + $220.00 = $450.00. Yearly total: $450.00 × 12 = $5,400.00, split as $2,760.00 base and $2,640.00 matches. Add a third match and the month becomes $560.00 and the year $6,720.00; drop to one match and it becomes $340.00 and the year $4,080.00. The base share rises as matches fall, because the base stays fixed while the matches line shrinks.
Every branch, checked
A $250.00 base with the same mahjong matches and per-match amount gives $470.00 a month and $5,640.00 a year. A $100.00 per-match amount with the same base and mahjong matches gives $430.00 a month and $5,160.00 a year. Three mahjong matches with the same base and per-match amount give $560.00 a month and $6,720.00 a year. One mahjong match with the same base and per-match amount gives $340.00 a month and $4,080.00 a year. Each branch changes exactly one input, so the difference from $450.00 isolates that input.
The reverses, worked backwards
The base behind $450.00 a month is $230.00: at $220.00 the figures are $440.00 a month and $5,280.00 a year, and at $250.00 they are $460.00 a month and $5,520.00 a year — a $10.00 step moves the month by $10.00. The per-match amount behind $450.00 a month is $110.00: at $100.00 the figures are $430.00 a month and $5,160.00 a year, and at $120.00 they are $470.00 a month and $5,640.00 a year — a $10.00 step moves the month by $20.00, because it applies to both matches. The mahjong matches behind $450.00 a month are 2: at 1 match the figures are $340.00 a month and $4,080.00 a year, and at 3 matches they are $560.00 a month and $6,720.00 a year — one match either way moves the month by $110.00.
What the defaults assume
The defaults assume a flat $230.00 base every month of the year, 2 paid mahjong matches every month, and a constant $110.00 per mahjong match. Real mahjong runs on the tournament calendar: a busy month may hold 4 matches and a quiet 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 mahjong matches is the honest edge: $230.00 a month and $2,760.00 a year, the base alone. Negative inputs are rejected — a base, a match count, or a per-match price below zero has no meaning here.
Who uses this
A twice-a-month mahjong player budgeting the year: the base covers club dues and the league share, the matches line prices the paid matches, and the year total is the annual budget. A parent pricing a child’s mahjong programme: the base is the monthly club fee and the mahjong matches are the paid match days. A club member comparing memberships: the base is the monthly upkeep allowance and the per-match price is the rate for matches beyond the package. A benefits manager comparing table-game allowances: the same base-plus-matches shape prices mahjong next to other table games 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 match count that mixes covered and paid matches, or a per-match price that omits scoring fees or tournament entries will each move the answer by exactly the amount of the error, every month. The model does not include travel, parking, a match-pack bought as a block, a mahjong set bought once, or employer reimbursement caps — price those separately, and re-check the allowance when the base or the per-match price changes.

Frequently asked questions
What counts as the monthly base allowance?
The recurring amount for club dues, a league fee, an insurance share and mahjong set and table upkeep: the figure set each month. Paid mahjong matches are not part of the base — they have their own line — and one-off charges such as a mahjong set belong in the month they are charged, not spread across the base.
What if my mahjong matches are covered by a club package?
Enter 0 mahjong matches, or a $0.00 cost per mahjong match, and the total is the base alone: $230.00 a month and $2,760.00 over 12 months on these defaults. A covered mahjong match makes its matches 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 matches a month here means 24 matches a year. Enter the busiest 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 package?
No. A package paid yearly is a lump sum, not a monthly base. Either leave it out and price paid matches only, or spread it yourself across the months it covers and add it to the base — but never do both, or the package is counted twice.
Why does one extra mahjong match move the month by $110.00?
Because the per-match price applies once per match: one more match adds exactly one per-match charge. The base does not change when matches change, which is why the matches line, not the base, carries the seasonal swing.
Can I use this for a mahjong allowance my employer pays?
Yes, as a pricing check: enter the employer base and per-match rate and compare the year total with the employer cap. The calculator prices whatever figures you enter; it does not check any employer rules.
