Calculate parameters before simulating

Please can anyone help! I was going to build a transformer with 220VAC to 12VDC and frequency 60kHz and constructing the transformer my own but before working physically i wanted to simulate it, but I need to know the inductance value of the side primary and secondary side, can you please tell me that how can I calculate the inductance. My core size is gonna be E13/8/5 with 270 primary turns and 14 on secondary.

Thank you all

Do you want to simulate
the design?
This design is encrypted. You cannot see
the constructive parameters, but you can simulate the results for your waveform inputs.
