Subscription Cost Calculator
Sum monthly subscriptions or model software seats, perpetual purchases, renewals and setup fees over an explicitly declared horizon.
Cost model
Only entered quotes and assumptions are modeled. No service is cancelled; taxes and discounts follow your declared bases. A month is never guessed as hours or days. Setup and other fixed fees occur once per component within the horizon. Duration conversion uses proportional cycles; use an explicit integer count for full-cycle billing. Tax bases include all component fees before or after the chosen discount. Minimum charges and charge rounding are applied after tax.
Exact report
Exact fractions; terminating decimals are printed exactly.
