The short version
- Flipping needs no levels or quests at all — only capital, which is why it works identically on a new account and a maxed one.
- Check trading volume before margin. A wide spread on an item nobody buys is a number on a screen, not money.
- The 2% sale tax means a spread has to clear roughly 2.04% before the trade makes anything.
- Buy limits cap what one item can earn per four-hour cycle, so spreading across several items is how you scale.
Flipping is buying an item below what people are paying for it and selling it above what people are accepting for it. That is the whole idea. Everything else — margins, volume, buy limits, tax — is detail that decides whether a particular trade is worth making.
It is also the only money-making method in Old School RuneScape that has no level requirements at all. A brand new account and a maxed one use exactly the same technique. The only thing that changes is how much you can put to work.
How the Grand Exchange actually matches trades
You never trade with a specific person on the Grand Exchange. You post an offer at a price, and the system pairs it with someone posting a matching offer on the other side. If you offer to buy at 1,000 GP and someone is already selling at 950, you get it for 950 — the Grand Exchange always fills at the better price for whoever placed their offer later.
This has one important consequence: an offer that fills instantly usually means you paid too much. If you set a buy offer well above the going rate, it completes immediately, and you have bought at the price sellers were happy with rather than the price you could have got.
Every members account has eight offer slots. Free accounts have three. Slots are the real constraint on how much you can earn, more than GP is at small bank sizes.
The two prices that matter
Every item has two numbers worth knowing:
- Buy now — what the most recent buyer paid to purchase immediately.
- Sell now — what the most recent seller accepted to sell immediately.
The gap between them is the spread. Flipping means capturing that gap: you place a buy offer near the sell-now price, wait, then place a sell offer near the buy-now price.
The important word is near. If you offer exactly the sell-now price, you are competing with everyone else doing the same, and you may wait a long time. Offering one or two percent above it will usually fill much faster, at the cost of some of your margin.
Your first flip, step by step
- Pick a liquid item. Anything trading tens of thousands of units a day will fill quickly, which matters more than the margin when you are learning.
- Check the numbers before committing. Look at the margin after tax and the buy limit. A 20 GP margin on an item with a 13,000 buy limit is 260,000 GP per cycle — better than most people expect.
- Place a buy offer slightly above the sell-now price. Buy as many as your budget and the buy limit allow.
- Wait. Do something else in game. Do not cancel the offer after two minutes.
- When it fills, place a sell offer slightly below the buy-now price.
- Collect. The 2% tax comes off your side automatically.
Do this once and the mechanics will make sense. Do it twenty times and you will start to notice which items behave predictably.
Good items to learn on — high volume, generous limits, always in demand:
The three numbers that decide everything
Volume
This is the one beginners ignore and it matters most. Volume is how many units trade in a day. It tells you whether an offer will fill at all.
A 50,000 GP margin on an item that trades four times a day is not an opportunity — it is a number on a screen. A 30 GP margin on an item trading two million times a day is real money you can collect every four hours, forever.
Buy limits
Every item has a cap on how many units you can buy in any four-hour window. This puts a hard ceiling on what one item can earn you per cycle:
maximum profit per cycle = margin × buy limit
That formula is why profit per limit is the number to rank by, rather than margin. An item with a huge margin and a limit of eight is worth less than a modest margin on something you can buy ten thousand of. Read more in how buy limits work.
Tax
Selling anything for 50 GP or more costs you 2% of the sale price. It comes out of your proceeds, not the buyer's payment.
This means a spread has to be wider than about 2.04% before the trade makes any money at all. On thin margins it is the difference between profit and slow loss. See how GE tax works for the cap and the exemptions.
Mistakes that cost new flippers money
Chasing a falling price. If your buy offer fills the instant you place it, the price may be dropping through you. You have just caught a falling item and will struggle to sell it for more.
Cancelling too early. Most flips need time. An offer that has not filled in five minutes has not failed; it is working. Cancelling and repricing upward is how you turn a good margin into a bad one.
Ignoring the buy limit. Buying your full limit of a thin-margin item and then finding you cannot buy more for four hours is fine — that is the system working. Buying an item with a limit of 70 and expecting to make millions is not.
Trading items you cannot exit. Capital tied up in something that trades twice a day is capital you cannot use. Always ask how you would sell before you buy.
Believing the spread is the profit. It is not. The profit is the spread minus tax, and only if both sides actually fill at the prices you planned around.
How much money do you need to start?
Less than most people think, but the amount changes what you should trade.
- Under 1M — high-volume, low-price items. Runes, ammunition, food, common supplies. Margins are pennies but they compound and the offers always fill. See low budget flipping.
- 1M to 10M — you can start using all your slots on separate items and hitting full buy limits on mid-priced goods.
- 10M and up — mid to high-value equipment and consumables become viable, and diversification starts to matter more than picking winners.
There is no threshold below which flipping stops working. There is only a point below which it stops being worth the time compared with just training a skill.
Where to go next
Once the mechanics are second nature, the skill is entirely in item selection. How to pick items to flip covers what actually separates a real opportunity from a wide spread, and margin and ROI explains why the same margin means completely different things on different items.
If you want to check a specific trade before making it, the GE profit calculator will tell you exactly what it leaves after tax.
Your first week, concretely
Advice like "start small and learn the mechanics" is true and useless. Here is what the first week actually looks like if you follow it.
- Day one: pick two items and do nothing clever
Choose two items from the high-volume screen that you can afford a full buy limit of. Buy both at the insta-sell price. Do not try to time anything. The goal today is to watch how long a fill takes, not to make money.
- Day two: add the sell side
List both at the insta-buy price. Note how long each takes. If one has not moved in a few hours, undercut by a fraction of a percent and watch what happens. That single observation teaches more about liquidity than any guide.
- Days three to five: add one item per day
Only add an item once you can afford its full limit without touching the money committed to the others. Stop at whatever number you can comfortably check twice a day.
- Days six and seven: measure, do not guess
Count what you actually made, not what the margins said you would. The gap between those two numbers is the thing worth studying.
What a good first candidate looks like
Four checks, in this order. An item failing any of them is not worth a slot while you are learning.
| Check | Threshold | Why it matters |
|---|---|---|
| 24-hour volume | Above 50,000 | Fills in minutes rather than hours |
| Price per item | 100–10,000 gp | Full limits stay affordable |
| Margin after tax | 1% or better | Survives the 2% drag |
| Buy limit | Large enough that a cycle is worth doing | 10 units of anything is not a business |
Cheap, liquid and boring is exactly right at this stage. The items that make experienced traders money are usually items that would bankrupt a beginner if they got stuck.
When an offer does not fill
This is the situation nobody prepares for, and the wrong reaction is the expensive one.
What most people do
Costly
Cancel, re-list a few percent worse, cancel again, chase the price down.
Each move locks in a worse position than the one before.
What to do instead
Cheaper
Check the volume first. If the item is genuinely liquid, wait — most fills that feel stuck are simply queued.
If volume is thin, accept one small loss and stop trading that item.
What to expect, honestly
With a few hundred thousand GP, a realistic first week is a few percent growth, not a multiple. That is not a failure of technique; it is what the maths gives you at that size. The value of the first week is that it costs you almost nothing to learn on, and the habits you build now are the ones you will still be using with a hundred times the capital.
Common questions
- How do you start flipping in OSRS?
- Pick a high-volume item, place a buy offer slightly above the sell-now price, wait for it to fill, then place a sell offer slightly below the buy-now price. The difference minus the 2% sale tax is your profit. No levels or quests are required.
- How much money do you need to start flipping in OSRS?
- There is no minimum. Under 1M you are limited to cheap, high-volume items like runes and ammunition, where margins are small but offers always fill. What changes with a larger bank is which items your capital fits, not whether the technique works.
- Why did my buy offer fill instantly in OSRS?
- Usually because you offered above the going rate, or because the price is falling through your offer. An instant fill often means you paid more than you needed to, so it is worth re-checking the item before selling.
