Two Calculators for Planning Your Cleanup

Two small calculators for the two questions the game does not answer: is processing actually worth the power, and how long is the rest of the Moon going to take.

Both tools run entirely in your browser. Nothing is sent anywhere, nothing is saved, and both show their formulas so you can check the result against your own save rather than trusting a black box.

1. Dust value calculator

Estimate hourly income from a dust stream, with the option to send part of it through a Pressure Chamber and a Stone Press. The useful output is the processing uplift — how much better the same dust does after processing.

Inputs

Set the raw dust value to whatever your depot currently pays. The multiplier is what matters, not the absolute number.

Output

$33,600/ hour

$560.00 per minute at these settings

Selling everything raw
$4,800 / hr
Processing uplift
7.00x
Moonstone produced
20.0 kg/min

Assumes the Pressure Chamber outputs sand 1:1 with dust, and the Stone Press consumes dust and sand in equal parts. Power, belt throughput and machine downtime are not modelled.

How the profit maths works

The model is deliberately simple, and it assumes the machines are fed:

  1. Your dust stream splits into raw, chamber-fed, and press-fed portions.
  2. The Pressure Chamber converts dust to Moon Sand 1:1, worth 3x.
  3. The Stone Press needs equal dust and sand, producing 2 kg of Moonstone per pair, worth 7x.
  4. The press can only consume what the sand branch can supply.
  5. Whatever is left over sells at its own multiplier.

Setting the chamber share to around 50% is usually optimal for a single press, because the press needs an equal amount of each input. Push it higher and you produce sand nobody consumes.

Watch outThe model assumes throughput you may not have

A Pressure Chamber processes up to 25 kg per minute and a Stone Press up to 20 kg of Moonstone per minute. If your inputs arrive faster than that, the surplus waits — and this calculator will overstate your income.

2. Moon completion calculator

Convert your current Moon percentage and cleaning rate into an honest time estimate for each of the four completion milestones.

Your save

Based on 163,830 total sectors, the figure shown on an in-game Moon map at launch.

10% of the Moon16,21911 days
50% of the Moon81,75157 days
100% of the Moon163,6660.3 years

A rate measured before automation will be far too pessimistic. Re-measure after adding J.O.O.N.A.S. or a new robot line.

How the time estimate works

  1. The map is assumed to contain 163,830 sectors, the figure shown on an in-game map at launch.
  2. Sectors for a milestone = total × percentage target.
  3. Sectors remaining = milestone sectors − your current sectors.
  4. Hours = remaining ÷ your measured sections per hour.

Measuring your rate properly takes an hour: note the sector count, play normally, note it again. Do not estimate from how fast a single hex feels.

TipThe pessimistic default is the point

Most players measure their rate during manual sweeping and are horrified by the result. That is accurate. Re-measure after you add automation — the number usually improves by an order of magnitude.

What these do not model

  • Power. A machine without enough kW produces nothing regardless of inputs. Pressure Chamber needs 10 kW, Stone Press 18 kW, a Solar Post gives 3 kW.
  • Belt throughput. Conveyors have a practical limit, and a long route through several mergers is slower than a direct one.
  • Downtime. Night cycles, empty batteries, blocked outputs and the occasional reversed belt are not in the model.
  • Region bonuses. Hex and region completion bonuses are real income but vary by region, so they are excluded rather than guessed.

The assumptions behind the multipliers are in the money guide, and the physical layout that keeps the machines fed is in the automation guide.
