How do I calculate how much I am actually spending on gambling each month?

Your actual monthly spend on gambling is a single number: total deposits minus total withdrawals over the period. That's it. Not your "bets placed," not your "time at the table" — just the net cash that left your bank account and didn't come back. Everything else is noise.

Where to pull the raw numbers

Ontario's regulated online casinos make this straightforward. Your account balance is always displayed in Canadian dollars and must be kept at zero or above — no negative balances are permitted, which means the math is clean. Log into each account you use, pull the transaction history for the calendar month, and tally:

• Total deposits in — every top-up you made
• Total withdrawals out — every cashout back to your bank

Net spend = deposits − withdrawals. If you deposited $400 and withdrew $150, you spent $250 that month. Simple.

If you play across more than one site — which is common in Ottawa given the range of operators registered in Ontario — repeat this for each account and add them up. Your bank or credit card statement is a useful cross-check: search for each operator's name and confirm the figures match what the casino's transaction history shows.

The tools Ontario operators are required to give you

You don't have to do the arithmetic entirely by hand. Ontario operators must offer deposit limits (capping how much you can put in over a chosen period) and loss limits (capping how much you can lose, calculated as winnings subtracted from the amount spent). The time periods available must include 24 hours, 7 days, and one month. Setting a monthly deposit limit is effectively a real-time spending cap that does the tracking for you — when you hit it, the site stops accepting deposits for the rest of that month.

These financial and time-limit functions must be easy to find, reach, and initiate or change at any time after you've registered. Look for them in your account settings, usually under a "responsible gambling" or "safer play" section. One important rule: if you've already set a limit and want to relax or remove it, that change only takes effect after a cooling-off period of at least 24 hours. That built-in pause prevents in-the-moment decisions from undoing your own guardrails.

For OLG.ca specifically, My PlaySmart Tools let you customize time and money budgets, and the My Play Customizer gives players control to set those budgets and stick to a plan. My Play History uses your actual play behaviour and patterns to surface habits that might be affecting your experience. It's a built-in spending diary, essentially.

The Responsible Gambling Council also offers a Cost2Play Calculator at responsiblegambling.org — a practical tool if you want a structured way to estimate spending across different game types.

One thing the account history won't show you accurately

Deposit history is not the same as loss history. If you deposited $200 on the 1st, played it down to $50, deposited another $200, and ended the month with $180 still in your account, your transaction history says $400 in / $0 out — but your real net loss is only $220 (the $400 deposited minus the $180 still sitting there). Always subtract your current account balance from your total deposits to get your true out-of-pocket figure for the month.

If you're playing on any site that doesn't carry the iGaming Ontario and BetGuard logos, those transaction records carry no regulatory weight and the spending controls described above may not apply — stick to registered operators to keep your data clean and your protections intact. The full list of registered operators is at the official iGaming Ontario registry.
