OSRS GE Tax Calculator
Enter any buy and sell price to instantly calculate your GE tax, post-tax profit, and ROI. Supports shorthand like "1.5m" and "500k".
How GE Tax Works
The Grand Exchange tax is a 2% fee applied to every sale on the GE, paid by the seller. It was introduced in December 2021 as part of the item sink mechanic. The formula is:
Tax = min(Sell Price × 0.02, 5,000,000)
Profit = Sell Price − Tax − Buy Price
ROI = (Profit ÷ Buy Price) × 100
The tax is capped at 5,000,000 GP per item. Items selling for more than 250M GP are effectively taxed at under 2%. Buyers pay the full listed price — only sellers are taxed.
Enter a sell price and buy price above to calculate profit and tax.
How to Use This Calculator
Enter the sell price — the price at which you are selling the item (what you receive before tax). Enter the buy price — the price you paid to acquire the item. You can use shorthand: "1.5m" for 1,500,000 GP, "500k" for 500,000 GP, or plain numbers like "1200000". Optionally enter a quantity to calculate total profit across a full buy limit cycle.
The calculator shows your tax per item, post-tax profit per item and in total, and your ROI as a percentage of your original investment. If profit is negative (shown in red), the flip is losing money after tax at those prices.
Why Tax Matters for Flipping
Before the GE tax was introduced, a 3% margin meant 3% pure profit. With the 2% seller's tax, that same 3% margin yields only approximately 1% profit — two-thirds of the apparent spread is consumed by tax. This makes it critical to use post-tax profit figures when evaluating flip opportunities.
A common beginner mistake is spotting what looks like a 20 GP margin, calculating 20 × 10,000 buy limit = 200,000 GP profit, and placing the trade — only to find that after a 2% tax on the sell price, the real margin per item was 6 GP, yielding only 60,000 GP for the cycle. Always calculate tax first.
07Flip's flip finder deducts GE tax automatically from all profit figures, so every margin and ROI shown on the dashboard is already post-tax. You should never need to manually adjust for tax when using 07Flip. This calculator is here for when you want to verify a specific trade or check a price you found in-game before committing.
Tax-Exempt Items
Not all items are subject to the 2% GE tax. Exempt items include:
- Old School Bonds — fully exempt from GE tax by design.
- Items under 100 GP — the effective tax rounds to zero, making them functionally exempt.
- Various very low-value supplies, basic tools, and other items defined by Jagex as exempt (the full list is in the game client).
For exempt items, the raw margin is the full profit — no tax deduction applies. This makes them particularly attractive for high-volume flipping since every GP of margin is captured as profit. See the GE tax guide for a fuller explanation of exemptions and their implications for flipping strategy.
