An excel spreadsheet is very helpful for these kinds of calculations.
The balance after 1 year is B1=B0*(1+r)-P, Where B0 is the initial balance and P is the payment=11000, r is the rate of interest = .05
After 2 years its B2 = B1*(1+r)-P = (B0*(1+r)-P)*(1+r) - P
= B0*(1+r)^2 - P(1 + (1+r))
so, by extension,
B10 = B0*(1+r)^10 - P*sum[(1+r)^(n-1)]
one equation, one unknown, solve for B0
After a protracted legal case, Joe won a settlement that will pay him $11,000 each year for the next ten years. If the market interest rates are currently 5%, exactly how much should the court invest today, assuming end of year payments, so there will be nothing left in the account after the final payment is made?
