I have been calculating networth monthly for nearly 10 years now. This data and trendline has proven extremely helpful in determining progress towards our goals. As importantly, if not more, I also track our monthly spending on the same sheet. My default chart shows the last 10 years of 4% of monthly networth versus my monthly spend, including 12 month moving average. It has been exciting watching the 4% line cross, then double my monthly spend line. This data gives me with the absolute confidence in determining my ability to retire early.
Without data, how do you determine your progress towards your goals?
I don't really need to determine my progress toward my goals. And I have no net worth goals anyway. The latter point is easier to address. We own two properties, both of which are rentals (we move a lot and are renters of the current place we live). It is in no way actionable for me to know if we have $400,000 in equity, or $600,000 in equity because we aren't selling regardless. And beyond that, what good would a net worth goal do for me? Knowing that if I sold everything I owned, I'd have about $1.2345 million does nothing for me because I will never sell everything I own. Therefore, that number has nothing at all to do with when I could retire.
Back to the first point, we save as much as we feel we can while still enjoying our present day. Knowing we will reach $1m invested (NOT net worth) in about 2 years if the market increases at x%, versus knowing it ill take 4 years to get to $1m if the market increases at x%--that doesn't matter. Because I won't know if the market actually increased at x% until those 2/4 years are up. Nor will I know if the roof goes at our rental earlier than expected and the car dies, and we spend $10,000 more than imagined, and that changes those numbers. Knowing the exact amount today doesn't actually tell me when I will reach my goal, nor does it cause me to panic and save more because I feel we have reached a pretty optimized, balanced point of saving.
If someone would be saving more if their back-of-napkin math, with many assumptions that could end up changing, tells them it's ~~~10 years to fire and they don't want to work 10 years, then maybe they should be giving strong consideration to saving more regardless, no?
So again, knowing net worth is meaningless because I will never liquidate everything. And for me, I don't need to know that $X is Y years away at A% interest to get me to be thoughtful with my spending.
