Question using Tibber and NordPool to log price

Hi all.
I’m new to HA and really like it. I’ve installed Home Assistant 2022.12.8 on a Raspberry Pi 4 and it’s running good. The problem is like: I have Tibber installed and present last hour (sensor.accumulated_consumption_current_hour_hemmet) and the price from NordPool (sensor.nordpool_kwh_se4_sek_2_10_025). What I would like to do is log the consumption price per hour (last hour * price) and then sum it per day/month and so on so I can check that the bill I get is correct. My problem is that I’m no good in programming so I really don’t know how to start this project - can anyone advice how to make this happen?
