Utilisation is the share of your working hours you can actually charge a client for. The currency symbol is for display only; no conversion is done.
Together that adds about a month, or a year.
Your minimum rate is only the floor. Pro (Business licence) is for freelancers and consultants: it compares pricing models, shows profit by client and builds retainers, with an optional discount.

Billable hours per week = working hours × utilisation. Annual billable hours = working weeks × billable hours per week. Required annual revenue = (monthly income × 12 + monthly costs × 12) ÷ (1 − profit margin). Minimum hourly rate = required revenue ÷ annual billable hours. Day rate = hourly rate × hours per day. Project price = hourly rate × project hours × (1 + buffer). Retainer price = hourly rate × retainer hours per month. Rates are calculated unrounded and rounded only for display.
Your biggest opportunity compares up to three changes: raising your rate when it is more than 5% below your minimum, billing more of your time when utilisation is under 65%, and adding a retainer when retainers are under 25% of your income. The first two are ranked by what they add per year. A retainer is shown as predictable monthly income and ranks first only when the other two do not apply.
Good to know: these are rates, not guaranteed earnings. They assume you can sell every billable hour at the rate shown. Income is take-home, and tax and social contributions are not modelled. Typical ranges are broad indicative figures, not audited statistics.
