Effective Annual Rate

If the effective weekly rate is 0.12%, the effective annual rate is? The correct answer is 6.43%. How you get this value? Thank you in advance!!!

Re: Effective Annual Rate

Hi vatso;

Experimentally, take a nice round figure of money like 100 dollars. Form the recurrence



with a(0) = 100 of course. Run it forward for 52 iterations, you get 106.43481. That is equal to an effective annual interest rate of 6.43 %.

Or use the formula

In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.
