So in Excel you can easily calculate annuities yourself, see below. But why don’t you use the convenient online calculators that calculate monthly, generate a payment plan, and even consider special repayments etc. (e.g. google Zinsen-berechnen de / hypothekenrechner.php).
EXCEL formula for annuities:
PMT(rate, nper, pv, [fv], [type])
[*]rate Required. The interest rate per period (payment period).
[*]nper Required. Specifies over how many periods the respective annuity (rent) is paid. ("nper" = number of payment periods)
[*]pv Required. The present value or the total amount that a series of future payments is worth at the present time. This value is also called "loan amount." (pv = present value)
[*]fv Optional. The future value (final value) or the cash balance you want to have after the last payment. If the argument fv is omitted, the value 0 (zero) is assumed, i.e., the final value of a loan is equal to 0. (fv = future value)
