Enter your buy price and how many turnips you bought to see profit.
How it works. Each week your island secretly rolls one of four patterns; prices are your buy price times a random multiplier from fixed ranges (Ninji's datamine). The forecast keeps only patterns consistent with what you've entered, so it tightens as you add data. The buy helper simulates thousands of weeks from last week's pattern to estimate what a fresh stack is worth. Bands show the full min–max the game can produce. Turnips rot next Sunday — sell before then. Still accurate on the Switch 2 Edition (Ver. 3.0), which kept the same algorithm. Your data is saved only in this browser.
