DEFINITION of 'Compound Net Annual Rate  CNAR'
The return on an investment after taking tax implications into consideration. The compound net annual rate (CNAR) is much like an investment's compound annual rate except that tax liability is taken into account. CNAR is a truer representation of investment returns because it illustrates investors' actual return after taxation, rather than just unrealized gains or losses.
INVESTOPEDIA EXPLAINS 'Compound Net Annual Rate  CNAR'
For example, if an investor invests $1,000 in a oneyear certificate of deposit (CD) with an interest rate of 5% paid annually, their expected annual return on this investment is $50. However, if interest income is taxed at 30%, the investor's compound net annual rate of return is actually 3.5%, or $35 ($50 x $0.70). As you can see, CNAR gives a much more accurate real return for an investor.
