The Simple Math of Early Retirement: How to Achieve Financial Independence Sooner

Achieving early retirement is a goal that many individuals aspire to, allowing them to enjoy financial independence and pursue their passions. While the concept of retiring early may seem daunting, it is not an unattainable dream. By understanding the fundamental mathematical principles and implementing key strategies, anyone can embark on the path to early retirement. In this article, we will explore the simple math behind early retirement and discuss practical steps to make it a reality.

The Power of Saving

Saving a significant portion of your income is crucial for early retirement. Let’s consider an example: Suppose your annual expenses are $40,000, and you aim to retire when you have accumulated 25 times your annual expenses, as suggested by the 4% rule (discussed later). In this case, you would need to save $1 million ($40,000 x 25) before you can retire. By saving more each year, you accelerate the accumulation of your retirement savings and bring early retirement closer.

The 4% Rule

The 4% rule is a commonly used guideline in retirement planning. It states that if you withdraw 4% of your investment portfolio’s initial value in the first year of retirement and adjust subsequent withdrawals for inflation, your money should last for at least 30 years. To apply this rule, determine your desired annual retirement expenses and multiply that amount by 25. For example, if you want $40,000 in annual expenses, you would need to accumulate $1 million ($40,000 x 25) before retiring. This calculation ensures you have enough saved to sustain your lifestyle throughout retirement.

The Magic of Compound Interest

Compound interest is a powerful force that can significantly impact your savings. Let’s say you start saving $10,000 per year at age 25 and invest it in a retirement account with an average annual return of 7%. By the time you reach age 45, you would have contributed a total of $200,000 ($10,000 per year for 20 years). However, thanks to the compounding effect of interest, your retirement account balance would be approximately $410,000, more than double your total contributions. This example highlights the importance of starting early and letting compound interest work over a long period.

The Role of Return on Investment

The return on your investments plays a vital role in determining when you can retire. Consider the following example: Suppose you aim to accumulate $1 million for retirement, and you save $30,000 per year. If your investment portfolio has an average annual return of 5%, it would take approximately 21 years to reach your goal. Here’s how the calculation works: After the first year, you would have saved $30,000, and with a 5% return, your balance would be $31,500. In subsequent years, you save an additional $30,000 and earn a 5% return on your growing balance. By the end of 21 years, your savings would have grown to approximately $1 million. However, with a higher return of 8%, you could achieve the same target in around 17 years. The power of compounding is amplified by higher returns, enabling you to reach your retirement goals sooner.

The Time vs. Money Trade-Off

Early retirement requires finding the right balance between saving aggressively and enjoying life along the way. Saving a higher percentage of your income allows for a shorter accumulation phase. Evaluating your priorities and determining the optimal savings rate can help you align your financial and lifestyle objectives.

Reducing Expenses

Reducing expenses is a crucial aspect of early retirement. By identifying areas where you can cut back and adopting frugal habits, you can accelerate your savings growth. For example, reducing your annual expenses by $5,000 can save you an additional $125,000 over 25 years. Every dollar saved not only reduces your expenses but also lowers the amount you need to save for retirement.

Conclusion

Achieving early retirement is a realistic goal when armed with the knowledge of the simple math behind it. By saving a significant portion of your income, following the 4% rule, harnessing the power of compound interest, and carefully managing your investments, you can pave the way to financial independence sooner than you might have thought possible. Remember to find the right balance between saving and enjoying life along the way, and stay flexible to adapt to changing circumstances. Start crunching the numbers and take the first steps towards the fulfilling and liberating journey of early retirement.

How much to retire in Singapore? (Reliable Sources Only)

A popular question (which is also related to financial Math), is how much money does it take for a person to retire in Singapore? We will collate reliable sources and their calculations in this blog post. By reliable, we mean that we will only select sources posted by major banks (POSB, OCBC, etc.), as well as those posted on major Singapore news outlets (Straits Times, Today, Channel News Asia etc.). Major insurance companies (AIA, Prudential) etc, can also be considered. Lastly, we also consider famous blogs like Mothership, Seedly, MoneySmart.

We will also post the relevant “metrics”, which include Retirement Age, Retirement Monthly Income, Years to Retirement.

Note that the Straits Times has estimated that a recommended Retirement Monthly Income is $1379, or around $1400. This covers mostly necessary items only, with just a few small “luxuries” like “occasional inexpensive meals out with family or friends, homes that are safe and comfortable, and an annual holiday to a nearby destination”. Note that air-conditioning and owning a car is excluded from the budget.

(Note that this list is not finalized, we will continue to add new sources here when we encounter one.)

1) OCBC: S$1.3 million

OCBC has a very interesting “fishing video” featuring a talking fish. In it, it is calculated that “to retire in 20 years and live on S$3,000 monthly, you need S$1.3 million”.

Retirement Age: 62

Retirement Monthly Income: $3000

Years to Retirement: 20

Talking fish from OCBC Video and its retirement calculation!

2) Mothership: S$720,000

This plan is worked out by Daniel, 29, and featured on Mothership. His retirement plan is to spend “30 years on a piece of farmland bought overseas, where he will build a ranch, and live off the earth surrounded by free-roaming livestock”.

Retirement Age: 50

Retirement Monthly Income: $2000

Years to Retirement: 21

The $720,000 can be broken down into S$360,000 cash and S$264,000 in his CPF Retirement Account at age 55 years old. Note that the above doesn’t quite add up to $720,000. That is because the CPF amount is for ensuring that he will “receive a steady stream of monthly payouts of around S$2,110 from age 65 for as long as he lives”.

3) Mothership: S$360,000

This is another plan from Mothership, by Melanie, age 25, female.

Retirement Age: 70

Retirement Monthly Income: $3000

Years to Retirement: 45

Again, the magic number seems to be “S$264,000 in her CPF Retirement Account at age 55”. Melanie can then defer her monthly payouts to 70. She will then receive around $2,600 per month for as long as she lives.

4) Seedly: $228,960 to $473,760

The Seedly blog calculates that one would need $228,960 to $473,760, depending on the age of retirement. It is summarized in the table below.

Retirement AgeAverage Life Expectancy Of SingaporeansYears Left To Enjoy RetirementRetirement Savings Required
5082.932.9$473,760
5582.927.9$401,760
6282.920.9$300,960
6782.915.9$228,960

The above is based on:

Retirement Monthly Income: $1,200

This is on the low side considering the Straits Times article that recommends $1379 for monthly retirement income. Nevertheless, the amount of total retirement savings required seems quite low compared to OCBC and Mothership.
