Gambling Loss Tracker
Turns deposits and withdrawals into the turnover behind your result, priced off published Nevada hold data. Nothing saved.
This tells you the scale of play a stated hold rate implies for a loss you already know you have. It says nothing about luck, and it is not a prediction about future results.
Total deposits, total withdrawals and your current withdrawable balance, the same three figures your operator’s own transaction history already has. Nothing you enter is saved or sent anywhere.

A turnover figure like this reveals scale, not luck. It is not a sign you are due to win back what you lost, and it is not evidence anything was unlucky. If you want to check the exact figures behind it, your operator’s own transaction history is the authoritative record, this page holds nothing to compare it against.
See the PGSI self-assessment and the responsible gambling page for free, confidential support, whatever your result above.

The idea
What this tool shows
Every operator's transaction history already has the figures: what you deposited, what you withdrew, and what is sitting in the account now. What it does not tell you is what those three numbers imply about how much actually went through the game. Memory is not a reliable source for that question either, in a specific, documented direction: a win stands out and a dozen small repeated deposits fade into the background.
This tool takes the same three figures every deposit/withdrawal tracker asks for and adds the one thing they do not compute: the turnover, priced at a stated hold rate, that would have had to run through the game to produce your result. The hold rates are not typed in from memory. The slot figures are pooled, dollar-weighted Nevada Gaming Control Board filings this site already sources and tests elsewhere (the house edge comparison table); the table-game figures are the same benchmarks that page prices its own comparison strip against.
The turnover figure is an estimate, printed as one: rounded to two significant figures, with the word "about" in front of it, because a number like this should never read as more precise than the model behind it. If you are ahead over the period you looked at, the page says so plainly and prints no turnover figure at all: the inversion only means something for a result that has actually happened.
FAQ
Questions players ask
What does this tool actually calculate?
Two things. First, your net position over the period: (withdrawals plus current balance) minus deposits, the same identity every deposit/withdrawal tracker uses. Second, only if that net position is negative, the turnover a stated hold rate implies: how much would have had to go through the game, at that hold rate, to produce a loss this size. Being ahead prints no turnover figure, because the inversion is only defined for a result that happened.
Why does it ask which kind of play dominated the period?
The turnover figure depends on the hold rate, and hold rate varies a lot by game: a slot machine and a blackjack table at basic strategy are not close. The six options are Nevada statewide slot figures (all slot machines, $1-and-up machines pooled, and penny machines) and three table benchmarks (blackjack basic strategy, European roulette, American roulette). Pick whichever dominated your play; the figure is an estimate either way.
Is the turnover figure exact?
No, and it is printed with the word "about" and rounded to two significant figures so it never reads as more precise than it is. It assumes every session in the period was played at the selected hold rate, that your results over the period were close to that hold rate's average, that no bonus or promotional credit distorts the deposit and withdrawal figures, and that the figures you entered are complete for the period. The averaging assumption usually moves the figure the most: a worse-than-average stretch needed less real turnover to produce the same loss than this figure shows, and a better-than-average stretch that still ended down needed more. For a table-game selection it is initial-bet turnover, the total wagered on the base hand, not total action: a hand played with doubles or splits puts more money on the felt than this figure counts.
Does a large turnover figure mean I was unlucky?
Not directly, and not because luck is irrelevant to the figure: it isn't, it's assumed away. The estimate assumes your results over the period were close to the hold rate's average, so it can't tell you whether a loss came from an ordinary bad stretch or from genuinely heavy play. If you ran worse than average, the real turnover behind your result was lower than this estimate; if you ran better than average but still ended down, it was higher. Either way, it is not evidence you are due to win back what you lost, and the expected value of further play at the same hold rate is negative regardless of where your net position sits right now.
Is anything I enter saved or sent anywhere?
No. The three figures and your selection exist only in this page's memory while you have it open, and are gone the moment you leave or reload. Nothing is written to storage on your device, nothing is put in the page's URL, and nothing is sent anywhere. This page carries none of the scroll-tracking event the site's other tool pages send. If you have accepted the cookie banner, the site-wide page-view analytics every page carries still records that this page was opened; it never sees a figure you typed.
Why doesn't this tool save my figures so I can track them over time?
Because a stored ledger of one person's gambling losses is the worst asset a site like this could hold, and your operator's own transaction history is already the authoritative record. Re-checking it there is better advice than a local copy on this site would be, and it is a trust position a site that stores your figures cannot make.
Methodology
How this is calculated
Net position is (withdrawals + current balance) - deposits, computed in computeLossTracker() in math.ts. When net position is negative, the same function prices the loss as turnover at the selected hold rate: turnover = netLoss / (holdPercent / 100). When net position is zero or positive, no turnover figure is computed or shown.
The turnover figure is rounded to two significant figures for display, in roundToSignificant().
Common misreadings2
- A large turnover figure is not evidence of bad luck, and it is not a sign that a win is due. It describes how much play happened, not what the next bet will do.
- Being ahead when you check is not evidence of an edge and is not a reason to keep playing at the same pace; the expected value of further play at any of these hold rates stays negative.
Assumptions4
- Your results over the period were close to what the selected hold rate predicts on average. This is the assumption that moves the figure most: a worse-than-average stretch needed less real turnover to produce the same loss than this estimate shows, and a better-than-average stretch that still ended down needed more. The figure cannot tell you which case applies to you.
- All play in the period happened at the selected hold rate. Mixing a slot session with a blackjack session and picking one rate for both understates or overstates the true turnover.
- No bonus or promotional credit is mixing into the deposit, withdrawal or balance figures you entered.
- The deposits, withdrawals and balance figures you entered are complete for the period you mean to measure.
Limits4
- The estimate assumes your results matched the hold rate's average, and this is usually the largest source of error in the figure, bigger than the other assumptions combined. It does not diagnose whether a loss reflects an ordinary bad stretch or genuinely heavy play.
- For a table-game selection the figure is initial-bet turnover only: the total wagered on the base hand. Doubles, splits and side bets put more money on the felt than this number counts.
- The hold rates are statewide Nevada averages (for slots) or optimal-strategy house edges (for table games), not the rate for any specific machine or table. A real machine or table can hold meaningfully more or less than its pooled average.
- The inversion is undefined for a reader who is not down, so no turnover figure is shown in that case, on purpose, rather than a misleading positive number.
