Overclock and Somersloop Calculator
Overclocking is not a linear trade. Push a Constructor to 250% and you get 2.5× the output for 3.36× the power. This calculator shows the real numbers for every overclockable building, and marks the point where each extra percent starts costing more than it returns.

How this is calculated
Power scales by an exponent, output scales linearly
For production buildings and miners, power draw follows
P = P_base × (clock / 100) ^ 1.321929.
The exponent is log2(2.5), which is the game's design rule:
doubling output costs 2.5× the power. It is stored in the game's own
building data as 1.321929. It was changed from 1.6
in patch 0.7.0.0, and some third-party calculators still use the old value.
| Clock | Formula | Reference |
|---|---|---|
| 10% | 4.77% | 4.76% |
| 50% | 40.00% | 40.00% |
| 100% | 100.00% | 100.00% |
| 150% | 170.91% | 170.91% |
| 200% | 250.00% | 250.00% |
| 250% | 335.78% | 335.77% |
Generators are the exception
Power generators do not use that exponent. Since patch 0.7.0.0 they
scale linearly: a Coal-Powered Generator at 250% burns 2.5× the fuel and makes
2.5× the power. This matters because the game data file still stores
1.6 in the exponent field for all four overclockable generators.
That value is a leftover. A calculator that reads the field without checking whether
the building is a generator will overstate generator fuel cost badly.
We override it to linear and keep the stored value visible in the math panel.
Somersloops multiply output and square the power
Output rises linearly with each Somersloop installed. Power rises with the square of
the fill ratio: P × (1 + slots_used / slots_total) ^ 2.
A fully slooped Manufacturer runs at 220 MW instead of 55 MW —
four times the power for twice the output.
What this does not cover
- Fuel consumption rates for generators are shown as a multiplier, not in items per minute. Use the building's base burn rate.
- Power Shard cost is not modelled. Clock speed above 100% requires shards regardless of the numbers here.
- Somersloop availability is finite in a save. This tool assumes you have them.
