Super User Root beer Posted May 21, 2009 Super User Posted May 21, 2009 I spent all night in math class calculating Compound interest and annuities. I got tell you, math amazes me. I'm not claiming to be a mathematical genius. I'm just amaze by versatile of math equations and how bored these people had to be to come up with the numbers when they first try to compute these formulas. Anyone want give me a compound interest or annuities problem to solve? I could use the practice before test on Tuesday. Quote
Super User Root beer Posted May 21, 2009 Author Super User Posted May 21, 2009 Now for grammar! F that! I rather do math than grammar. See, in math you are either right or wrong. In English, your professor/teacher will always find something to complain about on your paper. P.S. Math gets you further in life. Quote

Super User Sam Posted May 21, 2009 Super User Posted May 21, 2009 We are either strong in math or verbal skills. Some of us are equal, which is unusual. This is why we have insurance underwriters, engineers and accountants who do not like to speak and we have lawyers and authors who we can't shut up. Get tested and you will find out if you are either math or verbal. I scored equal which blew the tester's mind. Quote
Tokyo Tony Posted May 21, 2009 Posted May 21, 2009 So a guy has a fixed annuity and his first deposit, 1/1/09, gets 5.5% interest, compounded annually. Each subsequent deposit may have a different interest rate, depending on when it's applied. If his first deposit on 1/1/09 was $50K, what would the interest rate on his second deposit be if it were applied on 3/1/09 in the amount of $25K, and his balance on 1/1/10 were $80,425.00? I don't know if that's easier or harder than what you're used to, and I don't want to figure out the answer, but have fun if you want to Quote

I don't know if that's easier or harder than what you're used to, and I don't want to figure out the answer, but have fun if you want to This is harder than what I'm used too. Well, you said he collects interest 1 time through out 12 months. See, since he made the next deposit in March, he still hasn't collected interest on the original payment he just adding 25k to 50k which gives you 75. If you use the original 5.5% interest since you are still trying to collect an interest on that you get approximately 79,125.00 at the end of the year. However, if he still earned 80,425.00 he had an interest rate of approximately 7.5%.... Maybe 7% That's is best I can do. Never had to find interest rate. All 20 some problems including the compound interest problems all gave me the rate. I just had find balances and missing dollars. Example: A trust provides 10,000 to a county library at the beginning of each 3-month period for the next 2.5 years. If money is worth 7.4% compounded quarterly, find the amount in the trust when it began. As result of a court settlement, an accident victim is awarded 1.2 million. The attorney takes one-third of this amount, another third is used for immediate expenses, and the remaining is used to set up an annuity. What amount will this annuity pay at the beginning of each month for the next 20 years if the annuity earns 4.5% compounded monthly. All financial institution are required to give you interest rates anyway. I'm not expert on annuity, but I'm betting nearly 3/4 of all annuity if not all have multiple payments per year. Either monthly or quarterly. Quote

Tokyo Tony Posted May 21, 2009 Posted May 21, 2009 Haha, Root Beer - I don't know if I could calculate the answer to my question. I just know it's calculable. I usually just plug the numbers into a spreadsheet made by someone smarter that I am 8-) Quote

I usually just plug the numbers into a spreadsheet made by someone smarter that I am 8-) What is the answer anyway? Plug it in see what you get. I got 7.5 and when you plug it back in do it the normal way to calculate future value, I think it was 100 dollar more than the amount you put. So I just said "eh, it between 7-7.5%." I've never figure out interest rate before. My brother said there is a class, where there is a chapter you have to calculate an interest rate on a bond ready to be issue. Crap. I hate fixed income. :-[ Quote
Super User SirSnookalot Posted May 22, 2009 Super User Posted May 22, 2009 Glad I'm out of school and retired to boot ;D Only calculations I make these days is how many miles I'm over on my leased cars driving to my fishing spots. Quote
Captain Obvious Posted May 22, 2009 Posted May 22, 2009 OK I'll confess I like math, no I don't stay up all night reading an algebra book but I find math interesting and sometimes fun But I have one thing to say, grammar is much more important than math and as you can see by reading this I need to seriously work on it.
