What stock price does my put need to reach?

Direct answer
A put premium target does not correspond to one guaranteed stock price before expiration. Under a named pricing scenario, a lower underlying price will generally support a higher put value, but the required price also depends on the strike, checkpoint date, implied volatility, rates, and dividends. A different date or volatility input can produce a different stock-price condition for the same target
A put reverses the target direction
A long put gains intrinsic value when the underlying falls below the strike. Before expiration, however, its premium can also include time value, so subtracting the target premium from the strike does not answer every checkpoint question. That shortcut describes a simplified expiration relationship, not a live or future quote
The checkpoint preserves remaining time value
A target set for next week and the same target set for expiration are different scenarios. At the earlier checkpoint, the contract still has time remaining after that date. A reverse pricing calculation must value that remaining term instead of treating the option as though it expires at the checkpoint
Volatility can move the required put condition
Higher assumed implied volatility generally supports more time value for both calls and puts, while lower assumed volatility generally removes some of it. Holding the target and checkpoint fixed, that change can shift the underlying price that makes the modeled put value equal the selected premium
A modeled price is not an executable quote
Buyers and sellers determine the premium available in the market. The required underlying price is therefore best read together with the contract, target, checkpoint, volatility input, and quote time. It describes one internally consistent scenario; it does not promise that a bid or ask will appear at that value
Common questions
Can expiration break-even answer a put target set before expiration?
Not by itself. Expiration break-even uses the final payoff and net premium, while a checkpoint before expiration leaves time value in the contract. The earlier estimate needs a pricing model and stated assumptions
Does the required stock price guarantee my put will trade at its target?
No. It is the stock-price condition that matches the target in the selected model scenario. Live implied volatility, market liquidity, and available bids and asks can produce a different premium
