You should usually buy as many turnips as you can comfortably afford and store , but not literally every last Bell you own.

Quick rule of thumb

For most players in Animal Crossing: New Horizons:

  • Early game: 2,000–5,000 turnips (200k–500k Bells if price is ~100 each) is a safe starting range.
  • Mid/late game: It is common to invest 50–90% of your savings each week, limited by your pocket and storage space.
  • Very cautious approach: Only spend an amount that, if prices are bad and you must sell low, won’t make you quit the game out of frustration.

Remember: turnips bought one Sunday rot the next Sunday if you still have them, so only buy what you know you can track and sell during the week.

How to decide your number

Ask yourself:

  1. How many Bells do you have?
    • Take your current Bells and decide a risk level:
      • Low risk: 25–40% of your money.
      • Medium risk: 50–70%.
      • High risk: 80–90% (only if you’re okay with a big loss).
  2. What’s Daisy Mae’s price this week?
    • If she’s selling for 90–95 Bells, it’s a great time to buy more.
 * If she’s closer to 110 Bells, buy less, since profit margins are tighter.
  1. How much time will you actually play this week?
    • If you’ll check morning and afternoon prices most days, you can safely buy more.
 * If you’ll barely log in, buy less, because you might be forced to sell at a bad price.
  1. Do you have friends/online access?
    • If you use friends’ islands or sites like Turnip Exchange to sell at high prices, you can justify buying a lot more.
 * If you play solo with no online trading, stay conservative since you depend only on your own Nook’s Cranny prices.

A simple example

  • You have 600,000 Bells.
  • Daisy Mae’s price is 95 Bells.
  • You’re medium risk and can play most days.

Medium risk (about 60% of savings) → invest ~360,000 Bells.
360,000 ÷ 95 ≈ 3,789 turnips → round to 3,790 or just buy “max” until you’re near that amount.

If you’re brand new, you could cut that in half and buy ~1,800–2,000 turnips instead to learn how the Stalk Market feels.

Extra tips to avoid regrets

  • Track your prices: Check Nook’s Cranny morning and afternoon Monday–Saturday, and write them down or use a predictor site.
  • Aim for selling at 150+ Bells per turnip if possible (higher is amazing, 400–600 is jackpot).
  • Never hold until Sunday “just in case”; they will rot and you’ll lose everything.
  • Space: you buy in stacks of 10, and your pockets/storage limit how many you can keep on the ground or in rooms.

TL;DR

Start with a few thousand turnips, then ramp up to putting 50–80% of your Bells into turnips each week once you’re comfortable, as long as you can monitor prices and sell before they rot.
