Rule of 72 Definition:
Rule of 72 was introduce by luca pocioli nearly about 500 years back. Luca pocioli lived for 69 years from 1445 to 1514 calendar year. A book called ‘summa de arithematica’ has put the light on how you can estimate and evaluate duration to double your investment in simplest way by compounding interest formula. Rule of 72 means that Divide the number 72 with the rate of interest and witness the magical number which states number of years for your capital to double.

Their rule of 72 proof to be separated because of the interest amount per many years to get the estimated period necessary for doubling. Although scientific rule of 72 calculator and spreadsheet have functions discover their precise doubling period.
Rule of 72 Formula:
Here deriving Rule of 72 formula offer you to have simple calculation where you can solve your equation of doubling the investment time period.
Rule of 72 Formula: N = 72 / R.
Where: (1) N = Number of times, generally many years.
(2) 72 = Is the constant variable.
(3) R = Rate of interest.
Rule of 72 Example:
Rule of 72 Example: Suppose Mr. Shah meets bank representative to get latest fixed deposit schemes. Mr. Shah uncover that best bank offer is 10% annual interest; let’s see how many years it takes to double your investment capital with rule – 72.

As per formula says that Divide 72 by 18 (i.e. interest rate).
Result would be, Within 4 years Mrs. Maria would repay double amount if she fails to clear credit card bills.
Rule of 72 Calculator:
Here you can download rule of 72 calculator in excel from the below link. In this below link you get rule of 72 calculator along with rule of 114 calculator and rule of 144 calculator. You should download and can try by yourself to understand the concepts in much details.
Why does the rule of 72 work?
The value 72 actually convenient choice of numerator, since it’s lots of little divisors: 1, 2, 4, 6, 8, 3, 9, 12. It offers good approximation for annual compounding, and for compounding to typical rate. Your approximations may not be so correct to higher rates of interest.
For continues power of compounding, rule of 69 offers a valid result for any rates. Considering daily compounding looks close plenty of towards continuous compounding, for most reasons rule of 69, rule of 69.3 or rule of 70 is better than rule of 72 for everyday compounding. For the lower yearly rate compared to those preceding, 69.3 would definitely be more accurate than 72.
Rule of 72 Worksheet / Rule of 72 Proof:
Here in this below table specially prepared to showcase rule of 72 worksheet along with the rule of 72 proof. Also you can see the difference between rule of 70 vs 72 as well.
|Rate||Actual Years||Rate * Actual Years||Rule of 69.3||Rule of 70||Rule of 72|
Rule of 70 vs 72:
Here we will see the difference between rule of 70 and rule of 72 in the below rule of 70 vs 72 comparison. Check it out!
|Rule of 70||Rule of 72|
|(1) Rule of 70 means number of years it can take for a value towards doubling dividing that by 70 because of the variable’s growth rate. The rule of seventy is typically used to determine how long it would take for an investment towards doubling of the annual rate of interest.||(1) Rule of 72 means a simple way to figure out the actual quantity of time a good investment will take in order to double its value, provided a set yearly interest rate.|

Rule of 70 Formula: N = 70 / R
Conclusion: This person applications your rule of 70 and decides it would take around 7 years (70/10) to double their investment.
|(2) Rule of 72 Example: Assume one individual invests 200,000 in a 10% fixed rate of interest annually. This person wants to approximate the number of many years it would bring to double its investment.
Rule of 72 Formula: N = 72 / R

Rule of 114 Formula: N = 114 / R.
Where: (1) N = Number of years.
(2) 114 = Rules constant variable.
(3) R = Interest rate.
Rule of 114 Example:
Example of Rule of 144: Mr. Jack read in one of the article that, Inflation rate is growing every year with the average rate of 9% in the country.
Formula says that Divide 114 by 9 (i.e. rate of interest)

Rule of 144 Example:
Example of Rule of 144: Mr. Daniel read in one of the financial magazine that, country’s GDP is growing with the average rate of 7% every year.
