Slot RTP and Expected Loss Calculator.

Convert a slot RTP into house edge and estimate theoretical loss from coin-in. See the assumptions and why one session can differ sharply.

RTP session model

Use only configuration-specific published RTP.

$500.00 action · 4.00% theoretical edge$20.00theoretical loss; actual results can vary dramatically

How this calculator works

House edge is 100% minus RTP. At 96% RTP, the edge is 4%; $1,000 of coin-in therefore has a theoretical loss of $40.

Assumptions and limits

RTP is a long-run design figure. It does not describe hit frequency, volatility, or the result of a particular session.

Interpretation: Calculator results are long-run mathematical estimates under the entered assumptions. They are not session predictions, guarantees or recommended loss limits.
