Loan rules may differ by game version, difficulty or mod. This calculator uses simple interest on the entered principal for the full planning period.
Capital discipline
Borrow only when the return clears the cost
Compare the interest charge with the profit created by the purchased field, production point or machine. A positive project return can still be a poor use of debt when the margin is narrow.
Principal repayment is applied at the end of the period in this simple model, so it does not reduce interest during the selected days.
