The rule of 70 is used to determine the number of years it takes for a variable to double by dividing the number 70 by the variable's growth rate. The rule of 70 is generally used to determine how long it would take for an investment to double given the annual rate of return.
The Rule of 72 is a simplified formula that calculates how long it'll take for an investment to double in value, based on its rate of return. The Rule of 72 applies to compounded interest rates and is reasonably accurate for interest rates that fall in the range of 6% and 10%.
The Rule of 70 helps investors determine the future value of an investment. Although considered a rough estimate, the rule provides the years it takes for an investment to double. The Rule of 70 is an accepted way to manage exponential growth concepts without complex mathematical procedures.
72 ÷ number of years in which you want the investment to double = targeted annual rate of return. For instance, if you know you want your money to double in 6 years, the rule of 72 would have you looking for an investment with an annual rate of return of around 12% (72÷6=12).
The Rule of 70 is most effective when dealing with lower growth rates, typically under 10%. It is particularly useful for long-term investments with modest growth rates, such as retirement savings or bonds. The Rule of 72 is better suited for higher growth rates, typically above 10%.

The Rule of 70 is a simple formula used to estimate the time it takes for an investment or an economy to double in size based on its growth rate. By dividing 70 by the growth rate percentage, you can quickly determine the doubling time.
The 70% rule is a guideline that real estate investors use to estimate the maximum price to pay for a potential investment property. It suggests that an investor should only pay 70% of the After Repair Value (ARV) of a property, minus the cost of repairs and renovations needed.
The 70% rule for retirement savings says your estimated retirement spending will be 70% of your pre-retirement, post-tax income. Multiplying your post-tax income by 70% can give you an idea of how much you may spend once you retire.
Do you know The Rule of 72? It's an easy way to calculate just how long it's going to take for your money to double. To calculate, take the number 72 and divide it by the rate of return you hope to earn. That number gives you the approximate number of years it will take for your money to double.
As per this thumb rule, the first 8 years is a period where money grows steadily, the next 4 years is where it accelerates and the next 3 years is where the snowball effect takes place.
The 10,5,3 rule will assist you in determining your investment's average rate of return. Though mutual funds offer no guarantees, according to this law, long-term equity investments should yield 10% returns, whereas debt instruments should yield 5%. And the average rate of return on savings bank accounts is around 3%.
The “Rule of 70” is a guideline used to determine the amount of severance pay an employee should receive. It considers the employee's age and years of service, with the total equaling 70. For example, an employee aged 50 with 20 years of service would qualify under this rule.
According to the 70 percent rule, which has its roots in athletics, employees are most productive when a majority of their time is spent working at a less intense pace. That way, when work demands increase temporarily, employees have the reserve strength to meet those demands.
The Rule of 70 Formula
Hence, the doubling time is simply 70 divided by the constant annual growth rate. For instance, consider a quantity that grows consistently at 5% annually. According to the Rule of 70, it will take 14 years (70/5) for the quantity to double.
Application: The Rule of 72 is widely used in finance for calculating interest rates, investment growth, and inflation impacts. The Rule of 70 is primarily used in economic contexts, such as estimating population growth or GDP doubling time, where growth rates are typically lower.
The rule of 70 approximates how long it will take for the size of an economy to double. The number of years it takes for a country's economy to double in size is equal to 70 divided by the growth rate, in percent.
The Rule of 72 is a way to estimate how long it will take for an investment to double at a given interest rate, assuming a fixed annual rate of interest. You simply take 72 and divide it by the interest rate number.
The reason why the rule of 70 is popular in finance is because it offers a simple way to manage complicated exponential growth. It breaks down growth formulas into a simple equation using the number 70 alongside the rate of return.
Do you know the Rule of 72? It's an easy way to calculate just how long it's going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.
