You probably need to define your question more clearly. Coils without core usually calculated by relatively simple algebraic formulas that easy to implement into spreadsheet. Coils with core are a bit more complicated and transformers are totally different.

I agree with RF-OM you do need to be more specific if you need detailed help.

Hello DrBob13,

Thank you for these links. The first one is old and popular Nagaoka formula. I like Epcos link and will try it tomorrow. I have some crazy tasks now to design RF transformer with bandwidth from 5 to 5000MHz. It will be very interesting to see what is possible to get from ferrites in this 1000 times wide bandwidth.

Best regards,
