asset losses -10.78% in 7 days.

How do you solve for the daily compound interest rate to get a loss of -10.78% after 7 days compounding daily?

2. ## Re: Calculate Daily Compound Interest.

Compound interest formula:
y = x * (1 + R) ^ N

For this specific case:
x = 1
y = 1 - 0.1078
N = 7
R = ???

solve for R

R = POWER(y, 1/N) - 1

Specifically:
R = POWER(1-0.108, 1/7) - 1 = -16.16%

= POWER(1-0.108, 1/7) - 1 = -16.16%
