How can one fine be fair to a rich person and a poor person at once?
Two systems answer by separating what the offence deserves from what the offender can pay. Germany splits the fine into a number of daily units and a value per unit; England and Wales fixes one amount that must reflect seriousness and take account of means — upwards as well as downwards.
In short
A fine is the most frequently imposed criminal sanction in many systems and the least examined. It carries a problem no other sanction has in the same form: the same sum is a minor inconvenience to one person and a catastrophe to another, so a fixed amount punishes unequally while appearing to punish identically.
Why it exists
AnalysisEvery other sanction is measured in something the state distributes equally. A day of custody is a day for everyone; an hour of unpaid work is an hour. Money is the exception: a unit of it means different things to different people, so a sanction denominated in money cannot be equal and fixed at the same time.
How it works
Germany splits the calculation in two. Section 40(1) of the Criminal Code provides that the fine is imposed in daily units — Tagessätze — at least five and, unless the law provides otherwise, at most 360 full units. The number of units expresses the offence.
The value of a unit expresses the offender. Section 40(2) directs the court to determine it taking into account the personal and economic circumstances of the offender, as a rule proceeding from the net income the offender has or could have on average in one day, while ensuring that the offender is left at least the minimum income indispensable for living. A daily unit is set at not less than one euro and not more than thirty thousand.
The statute accepts that the second figure is often unknowable precisely. Section 40(3) permits the offender’s income, assets and other bases for assessing a daily unit to be estimated — which keeps the system working without requiring a financial investigation in every case.
England and Wales reaches the same problem with one figure and two requirements. Section 125(1) of the Sentencing Act 2020 provides that the amount of any fine must be such as, in the opinion of the court, reflects the seriousness of the offence. Section 125(2) requires the court, in fixing the amount, to take into account the circumstances of the case including in particular the financial circumstances of the offender so far as they are known or appear to the court.
What happens when a fine is not paid is where the two designs meet again. German law converts: section 43 provides that an irrecoverable fine is replaced by a default custodial sentence, with two daily units corresponding to one day, and a minimum of one day. The unit that was the sentence becomes the unit of the conversion.
Common misconceptions
Widely held beliefs that do not match how the system actually operates.
Common belief: A fine is a fixed amount attached to an offence.
In practice: Not in the systems described here. German law imposes a number of daily units whose value depends on the offender’s circumstances; English law requires the amount to reflect seriousness and to take account of financial circumstances.
Common belief: Taking means into account is a discount for poor offenders.
In practice: Section 125(3) of the Sentencing Act 2020 states that the duty applies whether the effect is to increase or reduce the fine. The point is equal severity, not lower figures.
Common belief: A day-fine system means the court decides how much someone can afford.
In practice: It decides two things separately: how many units the offence merits, and what a unit is worth for this person. Section 40(4) requires both to be stated in the decision.
Common belief: An unpaid fine is simply a debt.
In practice: Under German law an irrecoverable fine is replaced by a default custodial sentence at a statutory conversion rate of two daily units to one day. The sanction does not disappear; it changes form.
Common belief: Fines are a minor sanction not worth explaining.
In practice: They are the most frequently imposed criminal sanction in many systems, and the one whose severity varies most between people receiving the same nominal penalty. That is exactly why two legislatures legislate the calculation in detail.
How this varies between jurisdictions
A required section on every guide. Arrangements differ between countries, and we say how.
Two mechanics for the same equality problem.
- A number of daily units for the offence, and a separate value per unit for the offender, both stated in the decision — Germany, StGB § 40.
- Estimation permitted where the financial basis cannot be established — Germany, StGB § 40(3).
- One amount that must reflect seriousness and take account of means, increasing or reducing — England and Wales, Sentencing Act 2020 s. 125.
- A statutory conversion of an irrecoverable fine into default custody at two units to one day — Germany, StGB § 43.
Rights and accountability
Stating the number of units and their value separately makes a fine reviewable in two independent ways. A person can say the offence did not merit that many units, or that a unit was valued on a mistaken view of their circumstances, and the two arguments do not collapse into one another.
AnalysisThe default-custody rule is the reason the calculation matters beyond money. Where an unpaid fine converts into custody at a fixed rate, an amount set without regard to what the person can pay is a route into a prison, and the provisions requiring means to be considered are the safeguard against it.
What we could not establish
- Two systems are described from primary text. How often fines are imposed, at what levels, and how reliably they are collected are empirical questions this platform has not researched.
- Nothing here indicates what any offence attracts. It describes the mechanics of calculation, not any outcome.

- What has to be true before a court is allowed to send someone to prison?
In one system, a ladder written into statute. A community order needs the offence to be serious enough; custody needs it to be so serious that neither a fine alone nor a community sentence can be justified; and if custody follows, it must be the shortest term commensurate with the seriousness.
- Is imprisonment the normal outcome of a criminal conviction?
In the systems whose statutes are quoted here, it is the outcome the law tells courts to reach for last. Two legislatures write restraint into the text — one as a principle of sentencing, one as a rule about specific sentence lengths.
- What is a sentence supposed to achieve?
Four legislatures answer in their own words, and they do not agree — not on the purposes, and not even on whether the question belongs in sentencing law at all. Where a system puts its answer turns out to be as informative as the answer.

The authoritative German text of both provisions, each read directly (§ 43 at the corresponding URL). Supports § 40(1): "Die Geldstrafe wird in Tagessätzen verhängt" — the fine is imposed in daily units — at least five and, unless the law provides otherwise, at most 360 full daily units. Supports § 40(2): the court determines the amount of a daily unit taking into account the personal and economic circumstances of the offender, as a rule proceeding from the net income the offender has or could have on average in one day, ensuring that the offender is left at least the minimum income indispensable for living, with a daily unit set at not less than one and not more than thirty thousand euros. Supports § 40(3): the offender's income, assets and other bases for assessing a daily unit may be estimated. Supports § 40(4): the decision states the number AND the amount of the daily units. Supports § 43 in full: an irrecoverable fine is replaced by a default custodial sentence (Ersatzfreiheitsstrafe); "Zwei Tagessätzen entspricht ein Tag Ersatzfreiheitsstrafe" — two daily units correspond to one day of default imprisonment — and the minimum is one day. Cited for the STRUCTURE of the day-fine system, which separates the number of units from their value. It supports no claim about how often fines are imposed, about amounts in practice, or about any other country.

The official revised text, each section read directly at its own page. Supports s. 125(1): "The amount of any fine fixed by a court must be such as, in the opinion of the court, reflects the seriousness of the offence"; s. 125(2): in fixing the amount the court must take into account the circumstances of the case including in particular the financial circumstances of the offender so far as known or apparent; and s. 125(3): that this applies "whether taking into account the financial circumstances of the offender has the effect of increasing or reducing the amount of the fine". Supports s. 204(2): the court must not make a community order unless it is of the opinion that the offence, or the combination of the offence and associated offences, "was serious enough to warrant the making of such an order"; s. 204(3): the court must take into account all available information about the circumstances including aggravating and mitigating factors; and s. 204(5): the fact that the court MAY make a community order "does not require it to do so". Supports s. 230(2): the court "must not pass a custodial sentence unless it is of the opinion that" the offence, or the combination, "was so serious that neither a fine alone nor a community sentence can be justified for the offence"; and s. 230(3): that the section does not apply where a mandatory sentence requirement applies. Supports s. 231(2): a custodial sentence "must be for the shortest term (not exceeding the permitted maximum) that in the opinion of the court is commensurate with the seriousness" of the offence or combination, subject to stated exceptions for sentences fixed by law and required life sentences.
