Start cash is a batch estimate, not an hourly budget

An hourly profit rate and the cash needed to begin answer different questions. Mixing them can make a fast bank method look far more expensive than it is.

Making kwuarm potions was the highest low-effort result in a live 22 August 2026 snapshot. The model used 4,000 actions per hour and estimated 1,380,000 GP per hour. Its starting-capital figure was 1,101,500 GP.

That capital number does not buy a full hour of supplies. The current calculator prices a short batch. It multiplies the input cost for one action by one sixth of the hourly action rate, then caps the batch at 500 actions. At 4,000 actions per hour, one sixth would be about 667 actions, so the cap applies. The live inputs were worth 2,203 GP per action, which gives 1,101,500 GP for 500 actions.

This proxy keeps the result useful for players who want to test the method before committing a larger cash stack. It also prevents extremely fast actions from producing an unrealistic full-hour starting requirement.

The OSRS Money Maker finder shows the capital estimate next to profit, actions per hour, requirements, and risks. For this method it also warns that the published pace needs fast banking and may exceed the herb's four-hour Grand Exchange buy limit.

A player still needs to plan the session. Five hundred actions at the modeled pace covers about seven and a half minutes, not an hour. Reinvesting sale proceeds may extend the run, but slow sales, incomplete buys, and moving herb prices can interrupt that loop.

The safest first step is to buy one small inventory, make it, sell the output, and compare the observed margin with the live result. Starting capital tells you whether that test is possible. It does not promise that the market will support the headline rate for sixty minutes.
