Ranked by estimated profit per hour; Barrows repair has no hourly rate, so it ranks by its 4-hour buy-limit profit. Open a method for every option, its inputs and outputs, and the cited rate.
Inputs are priced at the latest instant-buy price and outputs at the latest instant-sell price, minus the 2% GE tax on each item sold and any NPC fee. Profit per hour multiplies that by an actions-per-hour rate cited from the OSRS Wiki on each method's page.
Of these 12 methods, making unfinished potions (Toadflax potion) leads at about +1,068,000 gp an hour after tax at current prices. That is an estimate, and prices move.
The GE only lets you buy a set number of each item every 4 hours. For fast methods the limit, not your speed, decides how much you can make, so each method shows what one 4-hour limit is worth.
Informational only: Offerbook never plays the game for you. gp only, no promise of income. For trading the GE itself, see today's flips, high alch profit, item sets and decanting.
