How the day-fine system works (art. 50 CP)
The fine is the pecuniary penalty par excellence of the Spanish Criminal Code. Unless the law provides otherwise, it is imposed under the day-fine system (art. 50.2 CP), a two-step method designed to make the punishment proportional both to the seriousness of the offence and to the financial capacity of the person who suffers it. First, the court sets a length — a number of days, months or years of fine — within the range the law provides for each offence and under the general sentencing rules. It then sets the daily quota, the amount in euros the convicted person must pay for each day of fine. The final amount is simply length times quota: a six-month fine with a €6 quota means 180 quotas (months count as thirty days, art. 50.4 CP) and therefore €1,080.
The legal limits: length and quota (arts. 50.3 and 50.4 CP)
The length has a minimum of ten days and a maximum of two years (art. 50.3 CP). Where the convicted party is a legal person, the maximum rises to five years. For computation purposes, months are deemed to have thirty days and years three hundred and sixty (art. 50.4 CP), so the two-year cap equals 720 daily quotas and the five-year cap, 1,800.
The daily quota ranges from €2 to €400 for natural persons. For legal persons, art. 50.4 CP provides a different and much higher bracket: from €30 to €5,000 per day. The combination of both factors explains the enormous breadth of the penalty: from the €20 of the absolute minimum fine (10 days at €2) to the theoretical €9 million of a legal person sentenced to the maximum (1,800 days at €5,000).
How courts set the daily quota: financial capacity (art. 50.5 CP)
Art. 50.5 CP contains the most important rule in practice: the court sets the amount of the quotas taking into account exclusively the offender’s financial situation, inferred from their assets, income, obligations, family responsibilities and other personal circumstances. The seriousness of the offence has already been weighed when setting the length; the quota measures only the ability to pay. Two people convicted of the same offence with the same fine length may end up paying very different amounts if one earns a high salary and the other is unemployed with dependent children.
Hence an essential practical consequence for the defence: document your real financial situation before trial. Payslips, benefit certificates, tax returns, mortgage or rent payments, loans and family responsibilities are the material with which a fair quota is argued. In forensic practice, where no financial investigation appears in the file, courts tend to set moderate quotas close to the lower end of the bracket, precisely because imposing high quotas without data on financial capacity would lack the reasoning the provision requires.
What if I cannot pay? Deferral, modification and default
Deferred payment: up to two years (art. 50.6 CP)
Before talking about default, exhaust the flexibility mechanisms. The court may, for justified cause, authorise payment of the fine within a period not exceeding two years from the date the judgment becomes final, either in one payment or in the instalments it determines. The trade-off is serious: failure to pay two instalments makes the remaining ones fall due — the whole outstanding fine becomes immediately payable.
Modifying the quota if your situation changes (art. 51 CP)
If the offender’s financial situation changes after the judgment — losing a job, falling ill, a drop in turnover — art. 51 CP allows the court, exceptionally and after due enquiry into that situation, to modify both the amount of the periodic quotas and the payment deadlines. It is an often overlooked route that can avoid reaching the default scenario altogether.
Subsidiary personal liability (art. 53 CP)
If the convicted person does not pay the fine, voluntarily or through enforcement (asset seizure comes first), they become subject to subsidiary personal liability of one day of deprivation of liberty for every two unpaid daily quotas (art. 53.1 CP). This is the rule that turns a monetary debt into deprivation of liberty: a wholly unpaid six-month fine (180 quotas) translates into 90 days. The law provides two alternatives to custody: for petty offences, the subsidiary liability may be served through permanent localisation (without the duration limit of art. 37.1 CP applying); and, with the offender’s consent, the court may order that it be served through community service, in which case each day of deprivation of liberty equals one day of work.
The regime is completed by three rules. First: for proportional fines — those set in proportion to the damage caused, the value of the object or the profit obtained (art. 52 CP) — subsidiary liability does not follow the one-day-per-two-quotas ratio; the courts set it at their prudent discretion with an absolute cap of one year(art. 53.2 CP). Second: subsidiary liability is not imposed on persons sentenced to a custodial sentence of more than five years (art. 53.3 CP). Third: serving it extinguishes the obligation to pay, even if the offender’s financial situation later improves (art. 53.4 CP).
Default by a legal person (art. 53.5 CP)
A company cannot go to prison, so its default regime is different. Payment of a fine imposed on a legal person may be split into instalments over a period of up to five yearswhere its amount demonstrably endangers the entity’s survival or the preservation of its jobs, or where the public interest so advises. If it still fails to pay the fine within the period set, the court may order its judicial intervention until full payment.
Day-fines and proportional fines: do not confuse them
This calculator works with the day-fine system, which is the general regime. But for certain offences — drug trafficking or tax offences, for instance — the Code orders the fine to be set in proportion to the damage caused, the value of the object of the offence or the profit obtained (art. 52 CP). In those proportional fines there are no daily quotas or time length, the offender’s financial situation remains a principal criterion of individualisation, and default is governed by art. 53.2 CP with the one-year cap already mentioned. If your fine is proportional, the result of this tool does not apply: have the case reviewed by a criminal defense lawyer.
