:Shouldn't we have:
:81000(1+i)^3 = .67*(77000*(1+i)^2+77000*(1+i)+35000)
:If that is true then I get 1+i = 1.2989
:or IIR = 29.89%
: : Shouldn't we have:
: : 81(1+i)^3 = 60.5*(1+i)^2+60.5*(1+i)+32.36
: : If that is true then I get 1+i = 1.4513
: : or IIR = 45.13%
To start, why 2 answers ? :) Maybe the good Doctor forged one of them?
Anyhow, 29.89% and 45.13% is (in my books) way too high;
not sure what you're doing: are you working it out as a PRE-TAX percentage?
If so, then it would be understandable.
I am confident my answer gives the exact "take-home-pay" rate (example):
Initial deposit : $5000
interest 1 year later: $500 : $5500
income tax on interest: $200 : $5300
The "actual yield" to the depositor is 6% (not 10%) : that's the way I did mine..
The "before tax" interest income is 10%
Of course, the interest cost to the BANK who pays out $500 is 10%.
