Calculators

Each one answers a specific question and shows the formula, the inputs and the assumptions behind its answer.

Investment

Building and upgrade ROI

Is this build or upgrade worth the money?

Payback period, return over your chosen horizon and annualised return for any capital outlay, with construction time counted against the return rather than ignored.

Loan and bond calculator

Should I borrow to fund this?

Total interest, repayment and the hourly cost of the debt — then whether the thing you want to fund is expected to out-earn it.

Planning

Capital allocation

How do these investment options compare?

Ranks competing options by profit per hour, shows return on capital separately, and states the hourly opportunity cost of choosing each alternative.

About these numbers

Every calculator uses one shared engine, so a figure means the same thing wherever it appears. Each result carries its formula, the inputs that produced it, and the confidence we have in the underlying game mechanic — the game’s operators publish no specification, so anything we have inferred is labelled as inferred. See how we calculate for the full list.
