I want to create a spreadsheet with multiple variables. This is a compound interest spreadsheet on a daily compound interest however it's also a reinvestment spreadsheet base on an at or above $50 calculated interest. The Interest rate changes also with the amount of money in your account. Here are the figures: $50 - $50,999 = .006 daily interest rate $51,000 - 100,999 = .007 daily interest rate $101,000 - $1,000,000 = .008 daily interest rate The daily amount of interest can be can be reinvested if the interest amount is = or > $50.00. If the Interest is < $50 it must remain in the account non-invested until it accumulates to = or >$50, then it can be reinvested. My excel spreadsheet has 364 rows (one for each day and I have it being reinvested because my amount is above the daily interest amount of $50. I know there is an eaiser way but I don't know it. What I need is what happens if someone only has $50 to invest initially? He would only receive 30 cents a day until he reaches at/above the $50 threshold . I would need a spreadsheet that shows daily interest and reinvestment with any amount from $50 - $1M of investment. I would also need something if I made another deposit to the account. Can someone help me with this? Or is this too complicated Thank-You
