Hello TANJA,
Hope you are doing good. Thanks for your query.
specifically, which method’s formula isn’t working for you? If you said that, I could understand well. Because all formulas are working on my PC.
The error message “There is a problem with this formula” usually appears when there is an issue with the syntax of the formula. If we take Method 2 as example, the following is the formula we used in cell E5:

=MIN((DATEDIF(C5,TODAY(),"d")+1)/(DATEDIF(C5,D5,"d")+1),100%)

It’s possible that the issue is related to the regional settings or the version of Excel being used on your PC. The formula we are using includes a percentage sign (“%“), which represents a percentage value. Depending on the regional settings or version of Excel being used, the formula may not recognize the percentage sign as a valid argument. To avoid any potential compatibility issues, you can modify the formula to use a decimal value instead of a percentage. For example, you can use “1” to represent 100%. I just told it as an example. It could be better if you tell me which formula isn’t working and which Excel version are you using.
Hope you can understand me. Happy Excelling.
