Planning for retirement doesn’t have to be complicated. One of the easiest and most powerful concepts every investor should understand is the Retirement Rule of 72. This simple formula helps you estimate how quickly your money can double—making it a valuable tool for long-term retirement planning.
At Plush Retirement, we help individuals and families use smart strategies like the Rule of 72 to build a secure, tax-efficient retirement. If you want clarity and confidence in your financial future, this guide is for you.
The Retirement Rule of 72 is a basic financial formula used to estimate how many years it will take for an investment to double based on a fixed annual rate of return.
72 ÷ Annual Rate of Return = Years to Double Your Money
If your investment earns 6% annually
72 ÷ 6 = 12 years
That means your retirement savings could double approximately every 12 years at a 6% return.
This rule is widely used by financial professionals because it’s quick, simple, and surprisingly accurate.
Retirement is a long-term goal, and small differences in growth rates can have a massive impact over time. Understanding the Retirement Rule of 72 helps you:
Visualize compound growth
Compare investment options
Set realistic retirement goals
Understand the cost of low returns
Make smarter, long-term decisions
At Plush Retirement, we use this rule as a starting point—then build customized strategies to help your money grow faster while managing risk.
Inflation quietly erodes your purchasing power. The Rule of 72 can also be used in reverse to estimate how fast inflation cuts your money in half.
Inflation rate: 3%
72 ÷ 3 = 24 years
That means your money loses half its value in about 24 years if it’s not growing fast enough.
This is why parking retirement funds in low-yield accounts can be risky. Plush Retirement focuses on strategies designed to outpace inflation and protect your lifestyle.
The Rule of 72 is extremely helpful when evaluating different retirement options:
Annual Return Years to Double
4% 18 years
6% 12 years
8% 9 years
10% 7.2 years
A small increase in return can significantly reduce the time it takes to double your retirement savings. This insight helps investors understand why professional planning matters.
While powerful, the Rule of 72 is only an estimate. It works best when:
Returns are consistent
Rates are between 4%–12%
It does not account for:
Taxes
Market volatility
Fees
Withdrawals
Risk tolerance
That’s where personalized planning from Plush Retirement becomes essential.
