Answer to Question #87264 in Finance for Fadhili

Question

Individual retirement accounts (IRA) allow some taxpayers to set aside kshs.160000 a year for retirement, and the interest earned on these accounts is exempt from taxation. If an individual starts selling aside money in an IRA early in her working life, its value at retirement can be substantially higher than the amount actually put in. Wanjiku sets aside kshs.160, 000 a year and starting when she is 25 years for an expected retirement age of 65, and expects to make 8% p.a return on investments. Calculate the total expected value when she retires. What if the income is taxed at 40% per year

Answer 1

Using annuity formula:

$FV = \frac{160,000*((1 + 0.08)^{40} - 1)}{0.08} = 41,449,043.$

If 40% tax is deducted, then:

$FV = \frac{160,000*((1 + 0.08*(1 - 0.4))^{40} - 1)}{(0.08*0.6)} = 18,410,196.6.$
