Joint Brokerage Account

Hey everyone, I am about 2 months away from my wedding date, and now that the wife-to-be and I are done saving for that, we are redirecting our future efforts towards investing.
I am investing through Vanguard and I would like to know thoughts on a joint brokerage account. It seems to me that one account with 2 donors would compound growth more quickly than two separate accounts. My backup option is to get an individual account and just put her money in there as well.

I appreciate the feedback!

Hi @tsouik! Congrats on your upcoming wedding! A couple quick things:

  1. whether you choose to open a joint account vs having separate individual accounts, won’t impact your ability to have compound growth over time. If you have two $10,000 accounts or one $20,000 account, they will both experience the same growth over time (all else equal).

  2. deciding on joint vs separate accounts is a personal decision. I’m a fan of having a joint account for mutual goals (buying a house, saving for a wedding, etc) and having separate accounts as well for individual expenses.

I think the most important thing with personal finances for a couple is to have clear expectations for joint accounts and have regular financial check ins to make sure you are on the same page with everything!

That makes sense to me, thanks. Maybe I’m missing something here, but it seems to me that we would get more long term growth with all our money in 1 place. For example, 20k in one place will grow faster than 10k in 2 different places.

Let’s look at an example.

Let’s say you have two accounts that each have $10 and both earn 10% a year. After year one, both accounts will have $11 in it. After year two, both accounts will have $12.10 in it. For a total of $24.20.

But now let’s say instead of having two accounts, you combine accounts and have one account with $20 and earn 10% per year. After year one, you will have $22 in the account. After year two you will have $24.20 in the account!

The number of accounts won’t make a difference in compound growth, assuming all the accounts are invested properly.
