Flipping is buying an item at the instant-sell price and reselling it at the instant-buy price. The difference — the spread — minus GE tax is your profit. No combat level required, no quest requirements, no membership gate. You need capital and an understanding of how the Grand Exchange actually works.
Every item on the Grand Exchange has two prices at any given moment: the price a buyer is willing to pay instantly (instant-buy, also called the high price), and the price a seller will accept instantly (instant-sell, also called the low price). The margin is the gap between them. Flipping means you buy at the low price and sell at the high price, keeping the spread.
In May 2025, Jagex raised the GE tax from 1% to 2%, capped at 5 million GP per trade. That means your margin needs to exceed 2% of the sell price just to break even. A 100 GP margin on a 10,000 GP item is 1% — that trade loses money after tax.
The margin shown in any tool is an estimate based on the most recent trade data. The real margin is what you discover in-game by placing a buy offer 1 GP above the market price and seeing what it actually fills at. This is called price checking. Do it before committing capital to a flip, especially on items you haven't traded before.
The procedure: buy 1 unit at a price you know will fill immediately (offer well above the listed buy price). The actual fill price tells you the real instant-buy value right now. Then sell it at 1 GP below what you think the sell price is and see where it fills. Those two numbers give you your actual margin, not an estimate.
Every item has a buy limit — a cap on how many units a single account can buy within any four-hour window. Once you hit the limit, the order sits unfilled until the window resets. Common buy limits: runes 13,000 per 4 hours; potions 2,000; most gear 8; high-volume commodities like arrows 11,000; rarer items 1 or 2.
Buy limits determine the maximum GP per 4-hour window achievable on any given item regardless of how wide the margin is. An item with a 500 GP margin and a buy limit of 8 earns at most 4,000 GP per window — trivial. An item with a 20 GP margin and a buy limit of 13,000 earns up to 260,000 GP — much more useful. Good flippers optimise GP per window, not margin per unit.

Every OSRS account has 8 Grand Exchange slots. The most important habit in flipping is keeping all 8 occupied. While one item is filling, seven others should be in motion. Sitting on one flip at a time means your gold is idle for the entire fill window.
High volume means orders fill quickly. A 500 GP margin is useless if it takes six hours to fill because nobody trades the item. Volume is the first filter, not margin size.
Margin stability matters more than raw margin width. An item with a consistent 150 GP spread is more reliable than one that swings between 0 and 800 GP — the latter will catch you with a bad fill half the time.
Avoid items with irregular supply: rare drops, quest reward items that spike during game updates, or anything whose price chart shows sudden cliffs rather than steady variation. Cliffs mean you're likely to buy at the peak and sell into the crash.
You can technically start flipping with any amount. In practice, below 100,000 GP the item selection is thin and margins are narrow. Most flippers find the 1–5 million GP range to be where meaningful hourly profit becomes possible. At 25 million GP, you can access most high-value flips. Above 100 million, options open up further but the number of genuinely liquid items at that price point shrinks.
Scale into flipping. Start with cheap high-volume items — runes, basic food, mid-tier ores — to learn how fills behave in practice before committing your entire stack to a single high-value position.
