What is an AC Turnip Calculator?

An AC Turnip Calculator is a specialized tool used by players of Nintendo’s Animal Crossing: New Horizons to predict the selling prices of turnips for the week. In the game, players can buy turnips from a character named Daisy Mae every Sunday morning. The goal is to sell these turnips later in the week at Nook’s Cranny for a higher price than the purchase price, an activity playfully known as the “Stalk Market.” The selling price changes twice a day, and it’s not entirely random. Instead, it follows one of four main patterns. An AC Turnip Calculator analyzes the prices you input to forecast which pattern your island is currently experiencing, helping you decide the best time to sell for maximum profit.

Anyone who participates in the Stalk Market should use this AC Turnip Calculator. Whether you’re a casual player looking to make a few extra bells or a dedicated trader aiming to pay off your final home loan, this tool provides invaluable insight. A common misconception is that these calculators can predict the exact price with 100% accuracy. In reality, they provide a probable range and identify the likely pattern, significantly improving your odds but not eliminating the “market” risk entirely.

AC Turnip Calculator Formula and Mathematical Explanation

The core of an AC Turnip Calculator isn’t a single formula but a pattern-recognition algorithm based on datamined information from the game itself. The prices are not random; they are generated based on one of four predetermined patterns for the week. The calculator works by comparing your entered prices against the known behaviors of these patterns.

The four main patterns are:

• Fluctuating/Random: Prices go up and down with no clear trend. It consists of a high phase and a low phase, randomly switching between them. Profit is possible but not guaranteed.
• Large Spike: This is the most profitable pattern. It starts with a few days of decreasing prices, followed by three consecutive, sharp price increases. The third increase is the peak, which can be as high as 660 bells, followed by a sharp decline.
• Decreasing: A consistently frustrating pattern where the price slowly but surely drops throughout the week. In this case, the best strategy is often to sell early for a minimal loss or visit a friend’s island.
• Small Spike: Similar to the large spike but less dramatic. It features a period of decreasing prices followed by a series of four smaller price increases, offering a modest profit. The peak is usually around 200 bells.

The calculator narrows down the possibilities as you enter more data points. For example, if your prices decrease on Monday and Tuesday but then jump up on Wednesday morning, the calculator will heavily favor the “Large Spike” or “Small Spike” patterns and advise you to wait.

Variables in the AC Turnip Calculator

Variable	Meaning	Unit	Typical Range
Buy Price	The price paid per turnip on Sunday.	Bells	90 – 110
Daily Prices	The selling price at Nook’s Cranny (AM & PM).	Bells	~15 – 660+
Pattern	The underlying price trend for the week.	Category	Fluctuating, Large Spike, Small Spike, Decreasing

Practical Examples (Real-World Use Cases)

Example 1: The “Large Spike” Windfall

• Inputs:
  • Buy Price: 105 Bells
  • Monday AM/PM: 88 / 84
  • Tuesday AM/PM: 81 / 77
  • Wednesday AM: 130
• Calculator Output:
  • Most Likely Pattern: Large Spike (90% chance)
  • Guaranteed Minimum: 130 Bells
  • Potential Maximum: 650+ Bells
• Interpretation: After a few days of discouraging, decreasing prices, a sudden jump occurs on Wednesday. The AC Turnip Calculator correctly identifies this as the start of a spike. The advice would be to HOLD and wait for the peak, which is likely to occur on Wednesday PM or Thursday. Selling now would be a mistake.

Example 2: The “Decreasing” Trap

• Inputs:
  • Buy Price: 92 Bells
  • Monday AM/PM: 85 / 81
  • Tuesday AM/PM: 76 / 72
  • Wednesday AM/PM: 68 / 65
• Calculator Output:
  • Most Likely Pattern: Decreasing (95% chance)
  • Guaranteed Minimum: 65 Bells
  • Potential Maximum: 85 Bells
• Interpretation: The prices have been falling steadily all week with no sign of an increase. The AC Turnip Calculator flags this as a Decreasing pattern. The best financial decision is to cut your losses and sell immediately, or better yet, check online forums or with friends to see if you can sell on their island where they have a more favorable pattern. Holding your turnips until Saturday will only result in a greater loss.

How to Use This AC Turnip Calculator

1. Enter Your Buy Price: Start by inputting the price you paid Daisy Mae on Sunday into the “Buy Price” field. This is the baseline for all profit calculations.
2. Log Prices Daily: Each day from Monday to Saturday, visit Nook’s Cranny to check the turnip price. There’s a morning (AM) price before 12 PM and an afternoon (PM) price after 12 PM. Enter each price into the corresponding field in the calculator. The more prices you enter, the more accurate the prediction becomes.
3. Analyze the Results: As you input prices, the “Results” section will update in real-time.
   • Most Likely Pattern: This tells you which of the four patterns your week is probably following.
   • Guaranteed Minimum: This is the lowest price you are guaranteed to see at some point during the rest of the week, based on the possible patterns.
   • Potential Max Price: This shows the highest possible price you might see if the most favorable pattern plays out.
4. Consult the Chart and Table: The chart visualizes your current prices and the potential future paths. The table provides a detailed breakdown of the price ranges for each possible pattern, helping you understand the risk and reward.
5. Make Your Decision: If the calculator predicts a “Large Spike,” it’s best to wait. If it predicts a “Decreasing” pattern, it’s wise to sell as soon as possible or find another island. This powerful AC Turnip Calculator is your best friend in the Stalk Market.

Key Factors That Affect AC Turnip Calculator Results

Several factors influence your Stalk Market outcomes. Understanding them can help you better interpret the results from our AC Turnip Calculator.

• Your Buy Price: A lower buy price (closer to 90 bells) gives you a larger profit margin and makes it easier to break even, even on a mediocre week.
• Previous Week’s Pattern: The game’s code makes it less likely to get the same pattern two weeks in a row. If you had a Large Spike last week, your chances for one this week are reduced.
• First-Time Buyer: The very first week you buy turnips on your island, you are locked out of the “Decreasing” pattern and have a very high chance of getting a “Large Spike” pattern.
• Data Entry Accuracy: The calculator is only as good as the data you provide. Missing even one price period can sometimes make it harder to distinguish between a Small Spike and a Large Spike.
• Patience and Discipline: A key factor is resisting the urge to sell too early. Seeing a price that’s 50 bells over your buy price is tempting, but if the AC Turnip Calculator suggests a Large Spike is likely, holding out could mean a 500-bell profit instead.
• Community and Friends: The single biggest factor that’s outside the calculator’s scope is your social network. If you have a decreasing week, the ability to visit a friend’s island with a high price spike turns a guaranteed loss into a massive profit.

Frequently Asked Questions (FAQ)

What is the highest possible turnip price?

In Animal Crossing: New Horizons, the maximum possible selling price for turnips during a Large Spike pattern is typically 660 bells. In very rare cases, it could be slightly higher, but prices over 600 are considered an excellent outcome.

What happens if I don’t sell my turnips by Sunday?

If you still have turnips in your inventory when the clock strikes 5 AM on Sunday morning, they will all rot and become worthless. You cannot sell spoiled turnips; you can only throw them away (or leave one on the ground to attract ants).

Does Time Traveling affect turnip prices?

Yes, significantly. Traveling back in time, even by one minute, will instantly rot all of your turnips. Traveling forward day-by-day within the same week is possible, but it can lock you into a specific price pattern, which our AC Turnip Calculator can help track.

When is the best day to sell turnips?

There is no single “best day.” It entirely depends on your weekly pattern. For a Large Spike, the peak is usually Wednesday or Thursday. For a Fluctuating pattern, you should sell whenever you see a price that gives you a decent profit (e.g., above 150 bells).

Is this AC Turnip Calculator guaranteed to be correct?

This tool is based on extensive research and datamined logic, making it highly accurate at predicting the *potential* patterns and price ranges. However, there is still an element of randomness, especially early in the week when multiple patterns are possible. The more data you provide, the more certain the prediction becomes.

Why are my prices only going down?

You are likely in a “Decreasing” pattern. This is an unlucky but common occurrence in the Stalk Market. The best advice is to use an AC Turnip Calculator to confirm the trend early and sell before your losses mount.

Can I just leave my turnips on the ground?

Yes, you can drop turnips on the ground outside your home to free up inventory space. Unlike in past games, they will not rot if left outside. However, visitors to your island can pick them up, so be careful!

Do I have to check prices twice a day?

For the most accurate prediction from the AC Turnip Calculator, yes. Missing a price point means the calculator has less information to work with, which can make it harder to differentiate between similar patterns like the Small and Large spikes until later in the week.
