Why Does Long Term Financial Growth Have to Start Young?
August 1, 2026
One word: Time.
The biggest advantage young people have is time. Maybe you don’t have family money to fall back on, a steady paycheck, or a head for numbers yet. You still have decades for your money to grow, and that’s your superpower.
Starting at 19, 22, or 25 gives your money years of growth that someone starting at 35 can’t get back. That matters because money gives you choices. It’s the difference between picking work you love in your 30s, 40s, and 50s and staying in a job you hate just to stay stable.
Have you ever heard of Compound Interest?
It’s interest that earns its own interest. Here’s an easy-math example (10% is a round number to keep the math simple, not a promise). Say you put $100 in an account that grows 10% a year:
Year 1: you earn $10, so you now have $110. Year 2: you earn 10% of $110, which is $11, so you have $121. Keep going for 10 years and that $100 becomes about $259, not the $200 you’d get from earning a flat $10 a year.
Real life is less tidy. A high-yield savings account might pay around 4% right now. The stock market has historically averaged around 7% a year after inflation over the long run, with big ups and downs along the way and no guarantees. Here’s what 4% and 7% look like over 10 years:
$100, once, left alone: about $148 at 4%, or $197 at 7%. $100 at the start of each year ($1,000 total): about $1,249 at 4%, or $1,478 at 7%. $50 a month ($6,000 total): about $7,362 at 4%, or $8,654 at 7%.
Some months you won’t have $50. Be frugal one month, put in $100 the next, and call it even. Consistency matters more than perfection.
Saving less earlier beats saving more later.
Picture two people, both earning 7% a year:
Shiloh saves $100 a month from age 20 to 30, then stops and never touches it. They put in $12,000 total and end up with about $140,000 at 60. Hudson waits until 30, then saves $100 a month for 30 years. They put in $36,000 total, three times as much, and end up with about $122,000.
Shiloh put in a third as much and still came out ahead. The extra ten years did the work.
Secondly ~ Don’t put all your eggs in one basket.
If you choose to save your money each month, and then invest that money for long term growth. Having in a diversified investment portfolio can help weather lots of market storms.
The S&P 500 is a great example of diversification. Instead of buying one company’s stock, you can buy a fund that tracks the S&P 500 and own tiny pieces of about 500 of the largest U.S. companies. If one company stumbles, the other 499 cushion the fall. (You can’t buy the S&P 500 itself, only funds that track it.)
Match your money to your goal.
Long-term savings goals (40+ years out, like retirement): investing gives your money the most room to grow. The ups and downs smooth out over decades.
Short-term goals & Emergency money (a car, an apartment): keep it in a high-yield savings account, which currently pays roughly 3.5–4.5% at many banks and credit unions. Rates change, so compare before you open one. Money you’ll need soon shouldn’t be in the stock market, because it can drop right when you need it.
- Think to yourself, what am I saving for? Do I have a checking account, do I have a low interest savings account? Do I have a long term savings account?
Do I set up a savings account at a Bank or credit union?
Banks are for-profit companies owned by shareholders. They tend to have more branches, ATMs, and app features, and online banks often offer the highest savings rates.
Credit unions are not-for-profit and owned by their members, which means you. Profits go back to members through lower fees and often better rates. You usually have to meet a membership requirement (where you live, work, or go to school), and there are fewer branches.
Either way, look for federal insurance. Banks are covered by the FDIC and credit unions by the NCUA, each up to $250,000 per person.
Start early, start small, and keep going. Time is the one thing you can’t get back later.
