Goal: $512,564 by March 2019

As a reminder, this is just an incremental goal along the way to 8x income by retirement. This mini-goal aims to get us to a milestone by the time I turn 45 and AS turns 40.

The milestone (which changes whenever our salaries change) is to get me to 3x my current salary, which is now $75,120, so $225,360; NT to 3x his, which is now $62,100, so $186,300; and AS to 2x hers, which in 2017 was $50,452, so $100,904).

Current balance: $411,632

January 2018 balance: $404,682

Progress: $6,950

Finally we have more retirement worth than we did in January! We didn't have any progress in February, March or April, so this isn't as good as it looks. To reach the interim goal by the end of our birthday month (March) in 2019, that's 10 months, so we'd need to contribute (or have assets appreciate) $100,932 -- $10,093 per month -- to reach it.

We rarely come close to that, so it's pretty unlikely. But I'll keep tracking anyway.
