Use this page for treadmill upgrade costs, reward milestone planning, farming estimates, and repeat-run ROI decisions.
Enter the cash, income, and price you can see on your own screen. The calculator answers two questions: how long until you can afford the upgrade, and whether that upgrade pays for itself.
Example scenarios use made-up numbers so you can see how the maths behaves. They are not game values, and they are not what the upgrade costs in your server.
Saving takes about 16m 40s in this example scenario.
Every number above is the one you typed. Nothing is preloaded from the game, so if a price or income value changes in a new build, this page cannot go stale — your input decides the answer.
The maths assumes your income stays flat while you save. Events, other players, and upgrades you buy in the meantime will move the real time.
Next: follow the progression checkpoints and confirm the price on your own screen before spending.
The treadmill is the upgrade this game's own how-to-play text points at, and the decision is arithmetic on your own screen: how long until you can afford the price you can see, and how long until the upgrade earns that price back.
Enter three numbers you can read in your own game: the cash you hold, the cash per second your placed Brainrots print, and the price on the upgrade you are looking at. The tool divides the gap by the income and returns the wait. It assumes nothing about the game.
Treadmill upgrades change the per-step Speed readout on your own plot. Take that reading before and after a purchase and the tool compares the income change with the price you actually paid, so the payback time comes from your readings rather than from a copied table.
It ships no cash ladder for treadmill levels, no timer table and no cash-per-second roster, because the developer publishes none and no rate for this experience survived the checks behind this site. Every number in a result is one you typed. The only prices this page holds are the Rubux bundles listed above, read from footage. The one worked cash example we can cite is a treadmill step printed as "Upgrade Level 1 -> Level 2 $15k" with later states reading +19 and +50 per step in the run reviewed on 2026-09-17: use it as a guide to what is readable on screen, not as a price.
One thing to settle first, because treadmill searches land here: the treadmill level, upgrade and multiplier tables and the speed calculators those searches return belong to the differently named game Steal An Egg, not to this one. This game does have a treadmill you can upgrade, but no level list for it has been published, so the tool above takes readings off your own screen instead. If you want the one treadmill reading this site does hold, it sits with the rest of the observed sample in the zone and system notes.
Six bundles from the shop panel in the one recording this site holds. Each price was read off the panel itself, so treat the list as a dated sample of one build and re-read the number on your own screen before you spend.
| Bundle | What the panel showed | Rubux |
|---|---|---|
| Aura Pack, Hatch 1 | Four item slots, labelled 40%, 30%, 20% and 10% | 35 |
| Aura Pack, Hatch 3 | Same four slots, three hatches | 80 |
| Aura Pack, Hatch 10 | Same four slots, ten hatches; the panel carried a Limited Time label | 260 |
| Speed +150k | A flat speed amount added to the account | 30 |
| Speed +1M | A flat speed amount; the purchase printed its confirmation on screen | 80 |
| Speed +10M | A flat speed amount | 225 |
The recording uploaded on 8 September 2026 by AlphaXD, "I Stole The Verity Egg in Steal a Brainrot Egg in Roblox". The Aura Pack panel is on screen around 3:02-3:08 and the Speed panel opens at 9:58. These are read off that footage, not from a developer post: the place publishes no price list, so one recorded session is the whole sample behind this table.
The Speed panel carried a second row of larger bundles. Its price buttons sat below the visible edge of the panel in every frame we hold, so those prices are not listed here and we did not copy them from anywhere else. The same applies to cash-priced upgrades: a treadmill or plot upgrade shows its price in your own game, and there is no published ladder to check it against.
Check the current egg list, code status, and progression mechanics before you commit cash.
