How is Compound Interest Calculated?


  • How does Clio calculate compound interest?


  • Clio Manage

Additional Information:



The rate you enter is the Nominal Annual Interest rate—the effective rate will be slightly higher due to the effect of the compounding period.


At the end of each interest period:

New Interest = Current Amount Outstanding * Nominal Annual Rate * (# days in interest period / 365)

New Amount Outstanding = Current Amount Outstanding + New Interest



30 day interest period, 12% nominal annual rate, $1000 outstanding

After 30 days, New Interest = 1000 * 0.12 * (30/365) = 9.863

New Amount Outstanding = 1000 + 9.863 = $1009.86
