Hello there
Just an observation here - I see lots of posts where people fret over their savings rate. While it's good to aim for the highest savings rate you reasonably can, I sometimes think people loose sight of the forest for all the trees.
Instead of obsessing about whether your savings rate is 44.5% or 41.8%, try simply to maximize how MUCH you save on any given year. If you suddenly get a raise or loose your job, your savings rate will change almost comically. But, what ultimately matters is how much you put into savings.
Try estimating how much you need to retire (your "FI Number") and then calculate how many years you will need to save with X% return every month to reach that number. For example, if you want to reach $800,000 and assume 6% returns, then saving $4,000/month will take you 11years, 3 monhts to reach your goal. If you bump it up to $5,000/month it will take just under 10 years.
