How to calculate RTP

[okin2o]

Hello guys, I was wondering if someone happens to know how to calculate the RTP?

My thoughts are:

your wins / wagered amount * 100 + 100 = RTP

Example:
lost -11$
wagered 65$

-11 / 65 * 100 + 100 = 83%

Hey, almost! You’re really close, but there’s a small adjustment to make.

The general formula is:

RTP=

Total Returned (wins/payouts)
________________________________________     * 100
Total wagered 

 

So in your case:

Wagered = $65

Net result = –$11 → that means your total returned was $65 – $11 = $54

Now plug that in:

RTP=

54
______   * 100 = 83,1%

65

So the correct RTP is ~83%.

Your formula with “+100” isn’t needed, because the ratio already gives you the percentage.

Keep in mind though: this is your personal RTP over a small sample size. The theoretical RTP of a game (what providers publish, like 96% for a slot) is based on billions of simulated spins, so your short-term results will usually differ a lot.
