How It Works
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. So, if the interest rate is 6%, you would divide 72 by 6 to get 12. This means that the investment will take about 12 years to double with a 6% fixed annual interest rate.
This calculator flips the 72 rule and shows what interest rate you would need to double your investment in a set number of years. Enter the number of years you'd like an investment to double and see what the interest rate would be to make it happen.
FAQS: Rule of 72 Calculator
How long does it take money to double?
The Rule of 72 is a simple formula that estimates how long it will take for an investment to double in value, given a fixed annual rate of return. To get an approximate number of years until your money doubles, you simply divide 72 by the annual interest rate. For example, if your investment earns a 6% APY (annual percentage yield), it would take about 12 years to double (72 divided by 6 is 12).
What interest rate would double your money in 5 years?
In this case, you would divide 72 by the number of years (5): 72 / 5 = 14.4. So, to double your money in approximately 5 years, you would need an annual interest rate of around 14.4%.
What is a 72 rule calculator?
A 72 rule calculator (or rule of 72 calculator) basically just makes it easy to figure out how long it will take to double your investment. Instead of manually dividing 72 (who has the time for that!) by the interest rate or the number of years, just use this rule of 72 calculator. You’ll instantly get the estimated time it will take to double your investment and the required interest rate to get there.
Is a rule of 72 calculator the same thing as a "double calculator?"
Yeah! You can call it that. The whole point of a rule of 72 calculator is to figure out how long it will take to double your investment with a specific interest rate.
