- Animal Crossing New Leaf turnip calculator tools predict your week's Stalk Market prices from logged data.
- Buy low, sell high: purchase turnips from Joan on Sunday mornings, then track prices twice daily.
- Four price patterns exist in New Leaf: Random, Decreasing, Small Spike, and Big Spike.
- Log every price (Mon–Sat, AM and PM) to narrow down the pattern and the guaranteed minimum.
- Sell before Sunday, or your turnips rot and become worthless.
What Is a Turnip Calculator?
An Animal Crossing New Leaf turnip calculator is a community-built prediction tool that takes your logged Stalk Market prices and tells you which weekly pattern your town is following, what prices are still possible, and when to sell for the best return. The mechanic itself—known as "stalk market" trading, or kabu trading in the Japanese original—has been part of the series since the beginning, and New Leaf uses a well-documented, deterministic pattern system that calculators exploit.
Every Sunday morning from 6 AM to noon, the boar vendor Joan wanders your town selling white turnips. Her price typically ranges from around 90 to 110 Bells per turnip, occasionally dipping lower or spiking higher. For the rest of the week, Reese at Re-Tail buys turnips at a price that changes twice a day—once at opening and again at noon. The calculator's job is to make sense of those twelve buy prices (Monday AM through Saturday PM).
New Leaf's turnip prices follow one of four hidden patterns chosen at the start of the week. A calculator compares your logged prices against every possible pattern outcome and shows which patterns remain possible, along with the guaranteed minimum and most likely price ranges. This turns guesswork into an informed decision.
The Four Weekly Price Patterns
New Leaf assigns one of four patterns to your town each week. Knowing which one you're in is the key to timing your sale.
| Pattern | Base Chance | Behavior | Best Selling Window |
|---|---|---|---|
| Random / Fluctuating | ~35% | Prices wobble up and down all week | Any local peak above 200 Bells |
| Big Spike | ~26% | Decline, then a sharp 2-period surge | The spike peak, often 500+ Bells |
| Small Spike | ~25% | Decline, then a modest 2–3 period rise | Mid-week spike, often 140–200 Bells |
| Decreasing | ~14% | Steady decline from Monday onward | Monday AM, before prices fall further |
Random Pattern
- Prices rise and fall repeatedly
- Guaranteed peak of at least ~150 Bells
- Check prices twice daily to catch it
Big Spike Pattern
- Prices fall early in the week
- Sharp spike for two periods only
- Peak can exceed 500–600 Bells
Small Spike Pattern
- Gradual decline after Monday
- Moderate recovery mid-week
- Sell during the rise, not after
Decreasing Pattern
- Monotonic drop all week
- No recovery—prices never rebound
- Cut losses and sell early
Big Spike windows last only two price periods—sometimes just a few real-time hours. If you see a sudden jump above 300 Bells, treat it as urgent and sell immediately rather than waiting for a better number.
How to Use the Turnip Calculator Step by Step
A popular community tool such as the ac-turnip.com Turnip Calculator is the standard reference workflow, and the same process applies to New Leaf-specific predictors. Follow these steps each week:
Record Joan's Sunday Price
Buy white turnips from Joan between 6 AM and noon on Sunday. Note her price per turnip—this is your Buy Price baseline that the calculator uses for everything else.
Log Prices Twice Daily
Visit Re-Talk and check Reese's turnip price each morning (opening to noon) and each afternoon (noon to close). Enter all twelve values—Monday AM through Saturday PM—into the calculator as you go.
Review the Pattern Probabilities
After a few entries, impossible patterns drop off. The calculator shows the chance of each remaining pattern, the guaranteed minimum you'll see this week, and the most likely price ranges per day.
Set a Sell Target
Compare your buy price to the predicted maximums. A common rule: sell at anything above 2x your buy price, and always sell if the calculator says the peak period has arrived.
Sell Before Saturday PM Ends
Unsold turnips rot at 6 AM Sunday, when Joan returns. Anything left over is worth exactly zero, so a guaranteed decent price beats gambling on a spike that never comes.
Use your own town's buy price and your own Re-Tail prices. Prices from a friend's town follow their pattern, not yours—though visiting friends' towns to sell at their high prices is one of the best legitimate profit strategies in the game.
Stalk Market Strategy Reference
Beyond raw calculation, a few field-tested practices separate consistent profiteers from turnip gamblers.
| Strategy | Risk Level | Typical Return | Notes |
|---|---|---|---|
| Sell at 2x buy price | Low | ~100% profit | Safe benchmark most weeks |
| Wait for Big Spike | High | 300–500% profit | ~26% of weeks; miss it and you may eat losses |
| Buy small (under 2,000 turnips) | Low | Varies | Caps downside on bad weeks |
| Sell in a friend's town | Low | Varies | Combine with online communities for high prices |
| Skip a bad Sunday price | None | 0% | If Joan charges 110+, consider a lighter buy |
Turnips cannot be stored in closets or the museum—only on the ground or in your inventory slots. Plan your purchase volume around how much floor space and how many letters-slots you can dedicate, and remember time traveling can spoil turnips if you rewind past a Sunday.
Weekly Turnip Routine:
- Buy turnips from Joan on Sunday morning (6 AM to noon)
- Log Reese's price every AM and PM period
- Update the turnip calculator after each entry
- Sell once price hits your target or the predicted peak
- Confirm zero turnips remain before Sunday 6 AM
Common Mistakes to Avoid
Even veteran mayors lose Bells to avoidable errors. These are the ones that hurt the most:
| Mistake | Consequence | Fix |
|---|---|---|
| Holding through a Big Spike | Prices crash the next period | Sell the moment a spike appears |
| Time traveling backward | Turnips rot instantly | Never rewind past a Sunday |
| Buying at 110+ Bells | Thin or negative margins | Skip or buy light that week |
| Checking prices once a day | Miss half the AM/PM windows | Check at open and at noon |
| Storing turnips in closets | Not possible in New Leaf | Use floor space in your house |
All white turnips spoil at 6 AM on the following Sunday, and any backward time travel can trigger rotting immediately. There is no way to un-rot turnips—only red turnips, a separate seed item, have a different growth mechanic.
FAQ
Q: What is an Animal Crossing New Leaf turnip calculator?
It's a prediction tool where you enter Joan's Sunday buy price and Reese's twice-daily Re-Tail prices. The calculator compares your data against New Leaf's four known price patterns and shows which patterns are still possible, the guaranteed minimum price, and the most likely peak windows for the rest of the week.
Q: When should I sell my turnips in New Leaf?
A reliable baseline is to sell at double your buy price. If the calculator shows a Big or Small Spike pattern, hold for the spike window—often Tuesday through Thursday—but sell immediately when the spike hits, because it lasts only two price periods.
Q: Can I use a friend's town prices in my calculator?
Enter only your own town's data for predictions, since patterns are tied to each town. However, you can physically sell your turnips at a friend's Re-Tail if their prices are higher, which is a popular cooperative strategy.
Q: What happens if I don't sell my turnips by Sunday?
They rot at 6 AM Sunday morning when Joan arrives, becoming worthless garbage. Selling at a mediocre price is always better than losing your entire investment, so clear your stock by Saturday night at the latest.
