The usual mistake
8:45 is not 8.45 hours. It is 8.75.
The clock counts in sixties; the invoice counts in hundreds. Anyone who copies the minutes after the decimal point loses minutes every single day, and always in the same direction: the one that bills less.
8 h 45 min → 8 + 45 ÷ 60 = 8.75 h
Minutes are divided by 60, not by 100. It is the only piece of arithmetic on this page worth memorising.
0:15 → 0.25
The quarters are the easy ones, and that is exactly why they mislead: 15, 30 and 45 minutes come out round at 0.25, 0.50 and 0.75.
1:10 → 1.17
Here the shortcut runs out. One hour and ten minutes is not 1.10: it is 1.1666… and on the invoice it is written with two decimals.
8:45 at 45 € an hour → 393.75 €
Read as 8.45 it comes to 380.25 €. Thirteen and a half euros less every day, two hundred and seventy over a twenty-day month.

Adding hours up is not recording them
This calculator is for a one-off sum. A working-time register must keep every clocking, make it available and leave a trace whenever it is corrected.

The clock-out was at 18:26, not at 21:40.
The correct clock-out is added with its reason and approval. The 21:40 entry remains in the record.
Sample entries.
Article 34.9 of the Spanish Workers' Statute, as worded by Royal Decree-Law 8/2019, requires the company to record the daily working time of every worker.
- Kept for four years
- It is not a history you can purge the day it takes up too much room. Four years from the moment the record is made.
- Produced on request
- To the worker, to their legal representatives and to the Labour and Social Security Inspectorate.

What comes up when you add hours
Four questions that change the result
Enter the weekly hours stated in your contract under «agreed hours per week». The calculator subtracts them from the worked total: a positive balance shows how much you worked above them and a negative one how much is missing. This is a mathematical difference; whether extra time legally counts as overtime depends on your contract, collective agreement and working-time arrangement.
Hours counted and, if you need it, kept
