F# - Turn simple for loop into more functional construct

I have this simple "Investment" type with a "lifetime" property:

type Investment = {
PurchasePayment: float;
Lifetime: float;
TaxWriteoff: float;
ResidualValue: float;
}

let CoffeMachine = {
    PurchasePayment = 13000.0;
    Lifetime = 4.0;
    TaxWriteoff = 2000.0;
    ResidualValue = 500.0;
}

I would like to iterate over the years of investment and perform some calculations for each year:

for i = 1 to int CoffeMachine.Lifetime do
    printf "%i" i
    // doSomething

Is there a way to avoid using for loop for that and write it in a more functional style?

Cheers,
