The 40% Rule

As many of you know I am a fan of Grant Cardone with a lot of his stuff and one of the key takeaways I look forward to applying to my life is the 40% rule. The 40% rule was documented in the Great Depression where the wealthy were saving 40% of their income, and its just that simple.  The 40% rule is saving 40% of your income before taxes, so if you make $10,000 a month that would require you to save $4,000 a month. If you start looking at the math you’ll realize after taxes and expenses that it is very difficult to achieve the 40% rule, and it is. Income is a priority for the 40% rule, you can’t save what you don’t make, and you must pay yourself first. I will show you a real example using my actual projected salary for my full-time job starting in June.

For my full-time job I have a $57,600 salary ($4800 monthly), a $5,000 signing bonus paid in first month, and a $500-month stipend for the first 18 months. It is a salary and commission pay plan however I will only account for the salary part since I don’t know how much I will sell yet.

Because I start mid-June, I calculated my gross income as half of my monthly salary ($2,400) + $5,000 bonus + $500 stipend = $7,900

June July August September October November December Total
4800 $7,900 $5,300 $5,300 $5,300 $5,300 $5,300 $5,300 $39,700
save 40% $3,160 $2,120 $2,120 $2,120 $2,120 $2,120 $2,120 $15,880
tax $1,738 $1,166 $1,166 $1,166 $1,166 $1,166 $1,166 $8,734
budget $3,002 $2,014 $2,014 $2,014 $2,014 $2,014 $2,014 $15,086

Looking at the table you can see my budget is around $2,000 and it will be less than that when you consider my 401k will also be pulled out of my income. I did assign a tax rate of 22% which is the bracket you would be in for this income however your marginal tax rate is less than that, either way I prefer to be conservative with my estimates. (I calculated my marginal tax rate to be 11.5% which would add $570 to my budget every month or $570 more to invest every month) For reference, I take data on my spending habits every summer when I am on internship or co-op. This summer I had no living stipend and was completely on my own, my monthly spending came out right at $2,000, though that includes some extraneous cost that most likely will not happen in the first 6-months of my full-time job. I also will be living at home or my girlfriend’s house during the first 6 months of my full-time job as I will be traveling 90% of the time during training.

Realistically looking at the first 6-months I will have extremely low expenses and may be able to save even more aggressively than what I have shown. Any extra income I can save will be put into my other investing accounts (Robinhood, Lending Club, and Stash). Ideally, I would like to save around $20,000 from my full-time job in 2019, which will help me achieve my $75,000 net worth goal. I would also like to try and purchase a 4-plex or duplex at the end of 2019 assuming all goes according to plan.

Looking at 2020, the saving and income numbers look the same as the later half of 2018. Commission will be included assuming I make sales and as my commissions come in, I plan to add those additional funds to my investment accounts as stated above. Looking at 2019 and 2020 I plan to save $40,000 with the 40% rule and invest additional income in my investing accounts. I plan to save in my Discover Savings account which earns 2.10% APY, which will add to my saving goals as well.

2020 will be difficult to keep in budget, I will then be paying rent and will be living full time in St. Louis. The $2,000 I lived on during internship was living like a poor college student for the most part, as I enter the real world, I expect my standard of living from the food I eat to the activities I participate in to be more expensive as well. However, I at least have an idea of what I spend monthly in preparation, I suggest to everyone to start documenting your spending to get an idea of your habits. If you need help or would like to look at how I do it, I cover it in THIS article.

As I mentioned earlier in the article, income is critical to achieving this aggressive saving plan, for your convenience I will run an example with a salary of $40,000, and I will use a marginal tax rate to ensure accuracy. I included above my actual budget above when marginal tax rate is considered ($2570/month).

budget $1,716 $1,716 $1,716 $1,716 $1,716 $1,716 $1,716 $12,015

As you can see with $850 less a month in your budget that makes things considerably more difficult depending on your life style and where you live.

I hope you learned some valuable information about budgeting and saving money, I’d love to hear about how you save and what your targets are!

Thanks, B^2
