Mrs. Olivia is new in the investment world. She wants to find out whether she should go for taxed investments or tax-free investments. She finds out that the taxed investments pay out the yield of 12% on an average. On the other hand, tax-free investments pay 8% on average. The prevalent tax rate is 35%. You need to guide Mrs. Olivia by choosing which investment would be more beneficial for her.

By using the formula, we get –

  • Tax Equivalent Yield = Tax Free Yield / (1 – Tax Rate)
  • Or, Tax Yield = 8% / (1 – 35%)
  • Or, Tax Yield = 0.08 / (1 – 0.35)
  • Or, Tax Yield = 0.08 / 0.65 = 0.1230 = 12.3%.

From the above calculation, we are clear that Mrs. Olivia certainly needs to invest in tax-free investments and not taxed investments.

Uses of Tax Yield Equivalent

Investors should use this formula to find out whether it is prudent to pay higher taxes for investing in taxed investments.

Let’s understand this by using a simple example.

Let’s say that Mr. Ramesh has decided to look at both taxed investments and tax-free investments. The idea is to reduce the tax payment as much as he can.

He finds out that the taxed investment offers a 9% yield. And a tax-free investment offers him a 6% yield. And let’s say that the tax rate is 40%.

To find out, he uses the tax yield.

By using the formula, he gets –

  • Tax Yield = Tax Free Yield / (1 – Tax Rate)
  • Or, Tax Yield = 6% / (1 – 40%)
  • Or, Tax Yield = 0.06 / (1 – 0.40)
  • Or, Tax Yield = 0.06 / 0.60 = 0.1 = 10%.

So, Mr. Ramesh finds out that taxed investment isn’t a good deal, and he should go for tax-free investments.
