Calculate Extra Costs

With Cinema Calc, you can add extra costs individually to each position with just two clicks.


In the "Settings" tab, you have an overview of all percentage-based extra costs.

We have already filled in the four most common extra costs for you - Künstlersozialkasse, employer contributions, agency commission, and §50a.

You can adjust each value, delete unnecessary extra costs, rename them, and add more.

Simply click the "Percentage" button, select the desired extra costs in the menu, and the surcharge will be calculated.

Rounding for Extra Costs

Since extra costs often have odd values, rounding is particularly important. But don't worry - Cinema Calc automatically takes care of that for you.

How Does Cinema Calc Round?

Cinema Calc rounds all displayed numerical values to two decimal places using rounding to the nearest even. Internally, Cinema Calc performs calculations with a value that is rounded at a much later decimal place. This ensures greater precision in the final result.

In the example below, the value £75.495 is calculated, but Cinema Calc displays £75.50.

Without precise internal calculation, an extra cent would be included in this example. Both outputs result in an unrounded value of £25.165, adding up to £50.33. If calculations were continued with the rounded values, the total would be £50.34. Therefore, Cinema Calc displays rounded values while internally calculating with accurate results.

When Does Rounding Occur?

Can Rounding Cause Issues?

We use specialized technology designed for calculating monetary values, so Cinema Calc always delivers accurate results. If you choose to manually verify the results, make sure that you or your calculator don't round intermediate values.
