What does this result mean?
A move-up readiness calculator translates your current bankroll into buy-ins at the next stake, then estimates the risk of ruin there from your win rate and standard deviation. It answers the bankroll part of moving up, not whether you are technically or emotionally ready for the tougher game. A larger stake can turn a comfortable roll into a thin one immediately, even when the cash balance has not changed. Use conservative performance inputs and treat a short hot run as unproven. If the result shows too few buy-ins or an unacceptable risk, keep building at the current stake. If the bankroll gate clears, separate a shot from a permanent move: set a fixed shot budget, a drop-back point and a review date before sitting. A lasting move still needs evidence that your decisions and edge survive the new pool.
