web based user login management database

I am looking into building a website with a function for a user to login and input information with integrated formulas and to come back at any point and update or view their info/history/export the data...etc. Similar to an online budget management function.

I am a newbie to the code world, apologies, and would be very grateful to someone that can point me in a direction to what code/system this would be effective for.

Thanks in advance.
