How to Use the Calculator

Start with a route you can repeat. Time one run from the moment you begin stocking to the moment you would naturally reset or start another loop. Enter that time in minutes, then enter the money you normally earn from the same kind of run. Add your current money and the cost of the upgrade you want. The calculator returns the runs needed, estimated time, remaining money, and money after the target is reached.

The calculator is intentionally simple because public sources do not list a complete upgrade formula. That makes your own values more useful than guessed tables. If your income changes after a purchase, update the money per run and compare the next target again.

Choosing Good Inputs

The most useful calculator inputs come from runs that look like your normal play, not from one lucky run or one interrupted run. If you are still learning the shelves, take three short runs and use the average time. If a friend joins, if the layout feels different, or if an upgrade changes how often you walk back through the store, update the numbers before planning the next purchase. A small change in money per run can move an expensive target by several loops, so the calculator is best used after every meaningful improvement.

The remaining money output tells you how much cash is still missing before the target. Runs needed rounds up because a partial run usually does not buy the upgrade by itself. Estimated time is the number of required runs multiplied by your run time, which makes it useful for deciding whether to buy now or keep farming. Money after target is the expected leftover amount after the final run and purchase. If two upgrades look close, compare them with the same run time and money per run so the decision is based on the purchase, not on changing inputs.

For early game decisions, run the calculator with small targets first. Shorter goals help you learn whether speed, carrying comfort, or interaction flow changes your actual income. For mid game planning, keep a note of your old money per run before buying an upgrade, then compare it with the new value after a few loops. If the improvement is small, the next purchase may need a different priority. For late game targets, estimated time is usually more helpful than runs needed because the difference between two expensive upgrades can be a full play session. The tool is meant to keep those tradeoffs visible without pretending the site has hidden official formulas.
