Importance of saving early

Saving early is important, as the power of compound interest will help you to reach your savings goal, even with low expected returns. The concepts apply for savings towards any goal, such as retirement, purchasing a home, or saving for an education. The longer the timeframe, the larger the impact of the power of compounding.
If you start late, you can still catch up. However, you'll need to invest more money, as compounding has much less time to have an effect.
==Compound interest==
Compound interest is interest added to the principal of a deposit or loan so that the added interest also earns interest from then on.Ontario Securities Commission, Growing your savings with compound interest, viewed March 3, 2018. This addition of interest to the principal is called compounding. A bank account, for example, may have its interest compounded every year: in this case, an account with $1000 initial principal and 5% interest per year would have a balance of $1050 at the end of the first year, $1102.50 at the end of the second year, $1157.63 at the end of the third year, and so on.
It is worth looking further at what is going on in this example. For the first year, the interest payment is $50, i.e. 5% of $1000, the original deposit (or "principal"). Since the interest payment is left in the account, there is now $1050 on which to earn interest on during the second year. Five percent of $1050 is $52.50, which brings the account to $1102.50 at the end of the second year. The third payment will be worth $55.13, i.e. 5% of $1102.50, bringing the total to $1157.63 after three years. The interest payment is increasing every year ($50, then $52.50, then $55.13), because interest is earned both on the principal and on the previous years’ interest payments. Over several decades, compound interest is a powerful force: after 30 years, our original $1000 would be worth over $4000All calculations in this article ignore inflation., with approximately half of the gain happening during the last decade.
==How much more will you get if you start early?==
If you invest $6000 at the beginning of each yearThis is the example presented by C.C. Gross, Need proof?, Vanguard blog, December 12, 2011, viewed February 7, 2015 (the equivalent of $500 per month, but placed at the beginning of the year to facilitate calculations), and start at age 55, assuming 4% annualized nominal return, your balance at age 65 will be about $75,000. If you start at age 40, you will end up with about $260,000. And if you start at age 25 your balance at age 65 will be about $593,000.Calculations are done as:
Starting at age 25: 592,959.22 = FV(4%, 65-25, -6000,0,1)
The last parameter of FV has Type set to 1, which represents a payment due at the beginning of the period.
Refer to the graph below.

To better understand what is going on, we can separate the amount invested in total from the growth of the invested money at 4% interest. Refer to the figure below.
Going from right to left, the lower (gray) bars represent your contributions. The sooner you start to invest, the more money you will have at retirement.
Now, look at the top (black) bars. Going from right to left, the sooner you start to invest, compounded interest has more time to work. Stated another way, the effect of compounding at age 20 will contribute much more significantly to your savings than contributions made later on.

==What does it take to catch up if you start late?==
Suppose you want $100,000 at age 65, and the interest rate is again 4%. If you start at age 25, you'll need to save only about $1000 a year. At age 40, you'll need to save about $2300 a year. And if you start at age 55, the amount needed is over $8000 per year.
:
The total amount needed to reach $100,000 at age 65 also increases as the saving period gets shorter:
