What makes a retainer work for both sides
The client gets reserved capacity and a lower rate; you get reliable income and less time spent selling. That reduced sales effort is what justifies a discount. If a retainer does not reduce your unbillable work or smooth your income, there may be no reason to discount at all.
Be clear about what the fee buys. An hours retainer reserves a block of time. A results retainer covers a defined monthly output, such as four articles or managed ad campaigns. Results retainers can pay better, but require tight scope control.
The formulas
Effective rate
Effective rate = Hourly rate × (1 − Discount ÷ 100)
Monthly retainer
Retainer = Hours × Effective rate + Passed-through costs
Contract value
Value = Retainer × Months
Worked example
A marketer offers 20 hours a month at their $100 rate less 10%, with $150 of tool costs passed through, on a 6-month contract.
- Effective rate: $90.00 an hour.
- Monthly retainer: 20 × $90 + $150 = $1,950.00.
- Client saving: 20 × $10 = $200.00 a month.
- Contract value: $1,950 × 6 = $11,700.00.
Terms to settle before you sign
- Unused hours. Decide whether they expire, roll over for a limited time or are refundable.
- Extra hours. State the rate for work above the included amount.
- Payment timing. Retainers are often billed in advance, since the fee reserves your time.
- Notice period. Agree how either side can end the arrangement, so you have time to replace the income.
Frequently asked questions
How much of a discount should I give?
Enough to make the commitment attractive, but no more than you gain through steadier income and less selling. Many people offer a modest discount or none and instead use priority access as the main benefit.
Should unused hours roll over?
Either can work. Rolling them over for a limited period is often seen as fair, while unlimited rollover can build up a liability of work you owe all at once.
What if the client always uses more hours than included?
Bill the overage at your agreed rate, then suggest moving them to a larger retainer. Regular overages are a sign that the package no longer fits.
Should a retainer rate ever be higher than my normal rate?
Yes, if it guarantees fast response times or limits your ability to take other work. Exclusivity and priority are valuable, and clients often pay a premium for them.
