A loan is quoted at 12% per annum with monthly compounding. A treasurer wants the equivalent continuously compounded rate. Which is closest?

The equivalent continuously compounded rate is about 11.94%. Use the conversion Rc = m × ln(1 + Rm/m) with m = 12 and Rm = 12%, giving 12 times ln(1.01), which is 0.1194. It is slightly below the quoted monthly-compounded nominal rate.

  1. A11.94%Correct
  2. B12.00%
  3. C12.68%
  4. D11.88%

Explanation

Rc = 12 × ln(1 + 0.12/12) = 12 × ln(1.01) = 12 × 0.00995033 = 0.119404, or 11.94%. The 12.68% option is the effective annual rate, a different measure. The 12.00% option ignores compounding frequency. 11.88% results from using ln(1.0099) type rounding error and is not the result.
