OSRS GE Tax Calculator

How to use this GE tax calculator

Enter the price you buy at and the price you expect to sell at. Optionally set a quantity for the full offer. The tool shows tax paid, GP you receive after tax, profit per item, total profit, ROI, and the lowest sell price that still breaks even after the 2% tax.

Use the item search to pull live Wiki buy/sell snapshots into the fields, then adjust to the offers you actually placed. For scanning many flips at once, use the GE Tracker Flip Finder, which already subtracts tax on every row.

How the OSRS Grand Exchange tax works

Since the 2022 economy update, every successful GE sale takes 2% of the sale price from the seller, rounded down per item, with a hard cap of 5,000,000 GP per item. Buyers do not pay this tax.

• Sell at 10,000 GP → tax is 200 GP → you receive 9,800 GP.
• Sell at 10,000,000 GP → tax is 200,000 GP → you receive 9,800,000 GP.
• Sell at 250,000,000 GP → tax hits the 5,000,000 GP cap.
• Sell at 500,000,000 GP → tax is still only 5,000,000 GP (1% effective), not 10M.

That last point matters for Twisted bows, scrapes, and other ultra-expensive items: above 250,000,000 GP the effective rate keeps falling, so after-tax math is not a flat 2%.

Break-even sell price after tax

If you buy an item for B, you do not break even by selling at B. You need a sell price S where S − floor(S × 0.02) ≥ B (or S − 5M ≥ B once the cap applies).

Rough rule under the cap: sell at least about B ÷ 0.98. Example: buy at 980,000 → break-even sell is about 1,000,000 before you make a single GP. This calculator solves the exact floored value so you are not guessing.

Why thin flips fail after tax

A 1% spread that looked free money pre-2022 is usually a loss now. If you buy at 100k and sell at 101k, tax on the sell is 2,020 GP — you lose money. Aim for spreads that still clear a few percent after tax, and prefer items with enough daily volume that the offer actually fills. Pair this page with the GE Tracker volume filter (5K+ by default) when hunting flips.

FAQ

How much is the OSRS GE tax?

The Grand Exchange charges 2% of the sale price per item, rounded down, paid by the seller when the offer completes. Tax is capped at 5,000,000 GP per item.

When does the 5M tax cap apply?

At 2%, the 5,000,000 GP cap is reached at a 250,000,000 GP sell price. Above that you still pay only 5M tax, so the effective rate drops below 2%.

How do I calculate flip profit after tax?

Profit per item = sell price − floor(sell × 0.02) − buy price (with the 5M tax cap). Thin margins often disappear once tax is included — always check after-tax numbers before locking a buy.

Who pays the GE tax — buyer or seller?

Only the seller. Buy offers are not taxed. Your buy price is what you pay; tax comes out of the sell side when your sell offer fills.

Is GE tax the same as high alchemy tax?

No. High Level Alchemy has no GE tax — alch value is fixed. GE tax only applies to Grand Exchange sales. Bond and some other special sales can differ; this calculator models the standard 2% item tax.

Why does my in-game profit not match?

Tax is calculated per item sold and floored (rounded down). Multi-item offers apply tax to each unit. If you used mid prices from a tracker instead of your actual fill prices, the numbers will diverge.
