What Is the Rule of 114?
The Rule of 114 is an easy mental math shortcut used by investors to estimate how long it will take for a lumpsum investment to triple in value. By dividing the number 114 by the expected annual rate of return, you get the approximate number of years required to multiply your money by three.
How the Rule of 114 Formula Works
The formula is incredibly simple:
Years to Triple = 114 ÷ Annual Interest Rate
For example, if you expect a 10% annual return from an index fund, 114 ÷ 10 = 11.4. It will take roughly 11.4 years for your money to triple. If you invested ₹1,00,000, it would grow to ₹3,00,000 in just under 11 and a half years.
Difference Between Rule of 72 and Rule of 114
Both rules are shortcuts for compound interest calculations:
- The Rule of 72 tells you how long it takes to double your money (72 ÷ Interest Rate).
- The Rule of 114 tells you how long it takes to triple your money (114 ÷ Interest Rate).
- There is also the Rule of 144, which tells you how long it takes to quadruple your money (144 ÷ Interest Rate).
These rules help you quickly compare different investment avenues and understand the timeline of wealth creation without needing a spreadsheet.
