How are your sims doing financially?

My sims have over §1M in cash but I have no idea what they are worth. They have a valuable nectar collection and countless valuable gems and paintings. I am currently playing the 5th gen heir (or was it 6th?) and they have made their money in the gardening career and from the sale of gems spawned from breaking space rocks. If I could bring myself to sell paintings, they would have a lot more money.
