Section One – Converts annual (nominal) rate to effective rate.
To see how these rates are calculated, click here.

In other words, this calculates the annual interest rate yield if it were compounded semi-annually, quarterly, etc.

Section Two – Converts effective rate to annual (nominal) rate.
To see how these rates are calculated, click here.

In other words, this calculates the compounded rates that are equal to the annual interest rate.

This calculator can convert annual (nominal) interest rates to effective interest rates and vice versa.
Just enter a number in the upper left input box, click calculate, then scroll down to Section One to see the annual rate converted into five rates (interest compounded semi-annually, quarterly, etc).

So, if you enter an annual rate of 10 in the upper left input box, then click “CALCULATE”, you will see that this annual rate is:
10.25% if compounded semi-annually
10.381289062% if compounded quarterly
10.471306744% if compounded monthly
10.515578162% if compounded daily
10.517091808% if compounded continuously

Section Two displays annual (nominal) interest rates.
Entering an annual rate in the input box then clicking calculate displays the equivalent compounded rates. Example: By entering 10 per cent annual interest, this calculator will show that this is equal to:
9.761769634 % compounded semi-annually
9.645475634 % compounded quarterly
9.568968515 % compounded monthly
9.532262476 % compounded daily
9.53101798 %compounded continuously
