re: How much should a person have in their savings by 25?

at 25, I was making about $45k, single, living with a roommate in a townhouse still driving my truck from HS with no car note.

I had about $30k in savings since I had very low living expenses (<$800/month) and I had no college loans. Unfortunately I was ignorant about roth IRAs at the time, so I just had this money in a regular savings account.

Of course, by 28, 90% of that savings was gone after buying a new truck, getting married, honeymoon, and buying a house
