Accident rate calculator: 1,000-worker rate, LTIFR and days lost per accident
Enter accidents, days lost, full-time equivalents and hours worked – the calculator shows the German 1,000-worker rate, LTIFR, TRIFR and days lost per accident and compares your rate with the national figure from the German Social Accident Insurance (DGUV).

Comparison with the DGUV figure for 2025
Your 1,000-worker rate of 22.7 is around 14% above the national figure of 19.9 reportable accidents at work per 1,000 full-time equivalents.
- A comparison with your own sector and previous years is more meaningful: accident insurance institutions (Berufsgenossenschaften) publish rates per 1,000 full-time equivalents and per 1 million hours worked in their annual reports.
- In small companies, chance shapes the picture: if the average is five reportable accidents a year, the annual figures will fall anywhere between two and nine in a good nine out of ten years purely by chance. So look at the rate over several years.
Converted to the US base of 200,000 hours, the LTIFR corresponds to 5.1 accidents with time lost per 100 full-time workers. When comparing with group or customer figures, always check the base.
Your figures correspond to around 1,600 hours worked per full-time equivalent. Check that hours and full-time equivalents cover the same year and the same groups of employees.
Next step
1,000-worker rate of 22.7 – now follow up causes and actions
With incident management in AMS Go, you record every accident in one place – at your desk or on site in the app. From the causes you derive actions with owners and deadlines, and statistics and KPIs show you where accidents cluster – as a basis for the safety committee meeting and the risk assessment. In the demo we show you what this looks like for your company.

The calculator uses the common definitions from our guide. There is no binding definition of LTIFR and TRIFR in Germany – only compare figures calculated on the same basis. The figures do not replace investigating the individual accidents.
How the calculator works
- 1
Define the accidents
Reportable occupational accidents are those causing death or more than three days of incapacity for work, not counting the day of the accident (Section 193 SGB VII). An accident with time lost involves at least one working day or shift lost after the day of the accident. Analyse commuting accidents separately.
- 2
Calculate the 1,000-worker rate
Reportable occupational accidents × 1,000 ÷ full-time equivalents. A full-time equivalent, formerly “Vollarbeiter”, is not a person but a unit of calculation: hours worked divided by the annual working hours of one full-time employee. The rate refers to one year.
- 3
Calculate the LTIFR and TRIFR
LTIFR = accidents with time lost × 1,000,000 ÷ hours worked. The TRIFR additionally includes accidents with medical treatment or restricted work but no time lost. What counts is the hours actually worked – holidays and sick days are not included.
- 4
Calculate days lost per accident
Days lost ÷ accidents with time lost gives the average accident severity. The days until the return to work are counted, not including the day of the accident. A single long absence can shift the figure considerably.
- 5
Round, compare, interpret
All figures are rounded to one decimal place. If a figure is missing, the calculator does not calculate the rate that depends on it – it does not assume annual working hours or any other values. It compares the 1,000-worker rate with the DGUV figure for 2025 of 19.9; your own previous years and sector figures are more meaningful.
Frequently asked questions
How do you calculate the 1,000-worker rate?
Divide the reportable occupational accidents in a year by the full-time equivalents and multiply by 1,000. Reportable accidents are those causing death or more than three days of incapacity for work. Example: 5 reportable accidents with 220 full-time equivalents give 5 × 1,000 ÷ 220 = 22.7.
What is the difference between the 1,000-worker rate and the LTIFR?
The 1,000-worker rate counts only reportable accidents and relates them to 1,000 full-time equivalents – this is how the DGUV and the accident insurance institutions calculate. The LTIFR counts all accidents with at least one day lost and relates them to 1 million hours worked; it is widely used internationally. US statistics use 200,000 hours instead – always check the base when comparing.
Where do I get full-time equivalents and hours worked?
Hours worked come from time recording or payroll – count the hours actually worked, not holidays or sick days. You get the full-time equivalents by dividing these hours by the annual working hours of one full-time employee in your company. The calculator deliberately does not assume a default value for this.
How meaningful is the comparison with the DGUV figure?
It gives a first orientation: according to the DGUV, there were 19.9 reportable accidents at work per 1,000 full-time equivalents in Germany in 2025. Your own previous years and sector figures from the annual reports of the accident insurance institutions are more meaningful. In small companies, chance shapes the picture heavily – look at the rate over several years there.
