The margin is the easy part. Whether you can hit it is the question.
RSpill prices every Grand Exchange flip against the tax, the four-hour buy limit and the cash you actually have — then tells you how much of the book is thin enough to strand you.

Margins you can actually hit
Most flip finders show you a spread and stop. Profit here is capped by whichever bites first — the item’s four-hour buy limit, or what you can afford. A 28k margin on an item costing 1.5m reads as zero profit on a 500k stack, because you cannot buy one.
Tax and breakeven, built in
The Grand Exchange takes 2% of every sale, rounded down, free under 50gp and capped at 5m. So buy at 100 and sell at 101 and you are down a gp. Every row carries the lowest sell price that actually clears.
Confidence, not just a number
A fat margin on something that trades twice an hour is a trap — you will sit on it while the price moves. Volume and price age ride alongside every margin, and thin or stale books are labelled as such.
Getting set up
- Set your cash stackEverything reprices around it. The table only shows flips you could actually fund.
- Add your RSNSkills, total level and XP pulled from the hiscores, with goal ETAs worked out from your own measured rate rather than a generic table.
- Log what you tradeRecord a flip and it tracks tax paid and realised profit, so your P&L is what you actually made, not what the margin column promised.
Questions
- Where do the prices come from?
- The OSRS Wiki’s real-time price API, polled every five minutes, with hourly trade volumes alongside. It is the same source most of the community uses.
- How is the tax calculated?
- 2% of the sale price, rounded down to whole gp, not charged below 50gp, and capped at 5,000,000gp per item. Bonds and a handful of tools are exempt. The rate has changed before, so it lives in one place and every number follows it.
- Do I need an account?
- Not for the flip finder or item pages. You need one to track RSNs, save a cash stack, log flips or set price alerts.
- Is this allowed?
- Yes. It reads public price data and public hiscores, the same as any wiki page. It does not connect to the game, read your client, or automate anything.
