Keeping Your Brain Sharp in Retirement

Stewart Willis

Retirement planning forces us to make many decisions, as well as calculations. And while a professional can help you with those, it can also help to sharpen up your math skills. Calculating percentages and interest rates off the cuff this isn’t difficult, but it can be intimidating without pen and paper. After all, you haven’t taken a math test in decades! But, maintaining your calculation skills is an important part of keeping your brain sharp in retirement.

Calculating Percentages

If something is 25% off, for example, think of that as a quarter of the price. If something costs $60 and is 25% off, divide 60 by 4, which is 15. Then subtract that quarter from the overall price, and you’re left with $45. If the percentage isn’t as simple as a quarter or half, like a 15% restaurant tip, there’s another technique. Figure out what 10% of the amount is by moving the decimal point one to the left. For example, if your bill is $40, 10% of that is $4. Then take half of that amount ($2), and add it to the 10% amount ($4) to get a 15% tip of $6.

Rule of 72

There is an easy way to estimate how long it will take an investment to double. If you know what the interest rate will be, take 72 and divide it by that rate. For example, if your investment earns an annual interest rate of 10%, divide 72 by 10 to get 7.2 years. This is a close estimate of how long it could potentially take that money to double.

Mental Workouts

Frequent mental workouts are an important part of an active retirement. It’s also the best time, since you’ll have more free time to devote to subject areas that interest you. Never stop learning or challenging yourself to think critically, no matter how old you are. Whether you enjoy crossword puzzles, Sudoku, reading or learning a bit of another language before taking a trip to a foreign country, staying sharp is critical in retirement.
