ABC Manufacturing Limited has a retirement plan that matches all contributions on a one to two basis. That is if you contribute $4000 per year, then ABC will add $2000 to make it $6000. ABC guarantees 7.8461% annual rate of return compounded semi-annually. Iris cen is a 20-year-old works as a financial Allen analyst at ABC. She is wondering whether she should take advantage of the ABC's retirement plan, or whether she should do it herself. If she, does it herself, she can earn 10.573% per year compounded semi-annually on her $4000 annual contribution (ABC will not make any contribution to do it herself plan.) Assume contribution will start two years from today and will be made every year till retirement. If Iris wants to retire 30 years from today, determine which plan will worth more at retirement, (ABC's retirement plan or do it herself plan)?
