Punch Walls To Escape Upgrade Calculator
Put in the price of the next upgrade and what a minute of your runs earns. You get the rubble you still need, how many full bags that is, and how long it takes; add the income the upgrade is supposed to add and you get the payback time as well.
Upgrade payback
The only measurement behind the defaults is one sale: 1,112 rubble paid $42.56 on 31 Oct 2026. Replace it with your own numbers and the result is yours.
Your runs make about $1.90 a minute at these numbers. If this upgrade lifts income by 20%, it pays itself back after 2 h 12 min of the same play.
What this cannot tell you: the next level's price is only on your own panel, prices differ between saves, and GREED or the LOOT GOBLIN class change the dollars per rubble. Hours of play are counted from the bag time you entered, not from a stopwatch this site ran.
What the numbers mean
Rubble needed is the price divided by what one rubble sells for. Full bags is that rubble divided by your bag capacity, so it answers the question the walk back to SELL keeps asking: how many trips is this upgrade. Payback time only appears once you say how much income the upgrade adds, because a price alone cannot tell you whether it is worth it.
Where the defaults come from
A recorded run on 31 October 2026 sold 1,112 rubble for $42.56, which is $0.038 per rubble, and a new run starts with a 150 bag. Those two numbers are measurements, not a published rate. The upgrade prices on your own panel move between runs and levels, so the price field is yours to fill.
When the result is wrong
Three things break the answer. If GREED or the LOOT GOBLIN class is raising your sell value, the real dollars per rubble is higher than the default. If the upgrade you are pricing changes bag capacity instead of income, the payback number describes the wrong thing. And if you are not sure the upgrade does what you think, the tool upgrade lines are read out on the tools page before you spend.
