Why retainers are worth a small discount

A retainer trades a slightly lower effective rate for something valuable to you: predictable income and reserved capacity. A modest commitment discount (often 5–15%) is reasonable because the client is buying priority access and you are buying stability.

Start from the hours you will reserve each month and your normal rate, apply the discount, and you have a defensible monthly figure plus its annual value.

Protect yourself in the terms

State clearly whether unused hours roll over (usually they do not) and what happens when the client exceeds the reserved hours (billed at your standard rate). A retainer should guarantee your capacity is paid for whether or not it is fully used.

Price the availability, not just the hours

A retainer that is simply a block of hours at a small discount is the worst of both models: you carry the obligation to be free, and the client pays less for the privilege. What a client is actually buying is priority — the guarantee that you will be there when they need you, which means holding capacity you cannot sell to anyone else.

Price that explicitly. A common structure is a monthly fee covering a defined number of hours plus a stated response time, with anything beyond the block billed at your standard rate. Make unused hours expire monthly and say so up front — rollover turns a retainer into a prepaid bank that a client will eventually draw down all at once, usually in the month you are busiest.
