To calculate a percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them. For example, 50% of 40% is: 50 / 100 × 40 / 100 = 0.50 × 0.40 = 0.20 = 20 / 100 = 20%. It is not correct to divide by 100 and use the percent sign at the same time; it would literally imply ...
The EU formula uses the natural convention that all time intervals in t i and s j are measured relative to the date of the first drawdown, hence t 1 = 0. However, any other date could be used without affecting the calculated APR, as long as it is used consistently: an offset applied to all times simply scales both sides of the equation by the ...
If the return in 2015 was 10% in Singapore dollars, and the Singapore dollar rose by 5% against the US dollar over 2015, then so long as there were no flows in 2015, the return over 2015 in US dollars is: 1.1 x 1.05 − 1 = 15.5%. The return between the beginning of 2015 and the end of January 2016 in US dollars is: 1.155 x 1.07 − 1 = 23.585%

The formula above can be used for more than calculating the doubling time. If one wants to know the tripling time, for example, replace the constant 2 in the numerator with 3. As another example, if one wants to know the number of periods it takes for the initial value to rise by 50%, replace the constant 2 with 1.5.
