annuity = fixed regular amount of money
FV = future value
i = interest rate
n = number of periods
A company needs to save 90,000 Euros in 5 years for new equipment. The bank offers a 4% interest rate if we regularly deposit the same amount each year. How many Euros do we need to deposit at least to obtain these funds?
So we substitute into the formula above
annuity=90,000 * ((0.04/(1+0.04) to the power of 5)-1)
annuity= 90,000 * ((0.04/(1.04) to the power of 5 -1)
annuity=16616.44 Euros
