Frequently asked questions about retainer agreement calculator
It depends on your agreement. Some retainers allow unlimited rollover, others cap rollover at 1-2 months of hours, and some are use-it-or-lose-it. Rollover caps prevent clients from accumulating years of unused hours that create accounting headaches.
Most retainers require 30 days notice to pause or cancel. This allows service providers to adjust capacity and replace revenue. Some agreements allow pausing for 1-3 months (e.g., during slow seasons) without terminating the agreement entirely.
Standard practice is that unused hours are forfeited upon cancellation—you have paid for availability, not just delivered work. Some agreements allow a 30-day wind-down period to use remaining hours, while others offer partial refunds (typically 50% of unused balance).
Rate increase provisions vary. Some retainers lock rates for the full term, others allow annual increases tied to inflation (CPI + 2-3%), and some include triggers for scope increases. Any rate changes typically require 30-90 days advance notice.
