Assuming that the interest rates are constant over the period of
investment,
=fv(5%/365,180,-100)

where the annula rate is 5%
number of days = 180
and daily investment = $100

if interest rate are also varing with time then take alook at the Product
function and determine FV of each cash outflow and sum it all up to
determine the FV
