Question 1

What is a retainer agreement?

Accepted Answer

A retainer agreement is a contract between a freelancer or agency and a client where the client pays a fixed monthly fee in exchange for a guaranteed number of hours or a defined scope of services each month. Unlike project-based work which has a clear start and end, a retainer is an ongoing relationship that renews monthly or on a set term (such as quarterly or annually). The retainer guarantees the freelancer predictable income and guarantees the client consistent access to the freelancer's time and expertise. Retainer agreements typically specify the number of hours included, the response time expectations, the types of work covered, and the terms for unused hours or overages.

Question 2

How do I determine the right number of retainer hours?

Accepted Answer

Start by analyzing the client's typical monthly needs. Review the past 3 to 6 months of work you have done for them (or similar clients) and calculate the average monthly hours. Add a small buffer of 10% to 15% for variability. If you are setting up a retainer with a new client, begin with a conservative estimate and adjust after 2 to 3 months of data. Common retainer sizes are 10 hours per month for light maintenance work, 20 hours for regular ongoing projects, and 40 or more hours for near full-time embedded roles. It is better to start with fewer hours and increase later than to overcommit and have the client question whether they are getting value for unused hours.

Question 3

What happens with unused retainer hours?

Accepted Answer

This depends on your retainer agreement terms, and there are several common approaches. The most freelancer-friendly policy is "use it or lose it," where unused hours do not roll over to the next month. This is fair because you reserved time in your schedule for the client regardless of whether they used it. A middle-ground approach allows partial rollover — for example, up to 25% of unused hours can be carried forward for one month. Some clients prefer full rollover, but this can create problems if hours accumulate and the client suddenly requests a large burst of work. Whatever policy you choose, make it explicit in your contract to avoid disputes.

Question 4

Retainer vs project-based work — which is better?

Accepted Answer

Both models have strengths, and most successful freelancers use a mix of both. Retainers provide stable, predictable income that reduces financial anxiety and business development costs. They also deepen client relationships and allow you to do your best work because you deeply understand the client's business over time. Project-based work, on the other hand, often commands higher effective rates because clients pay a premium for your availability on a one-time basis. Projects also allow more variety in your portfolio and prevent you from becoming too dependent on a single client. A healthy freelance business might aim for 50% to 70% of income from retainers for stability, with the remainder from higher-value project work.

Question 5

How do I increase my retainer price over time?

Accepted Answer

Plan for rate increases from the start by including an annual review clause in your retainer contract. Common approaches include an automatic annual increase tied to inflation (typically 3% to 5%), a performance-based increase after demonstrating measurable results, or a renegotiation at each contract renewal. When proposing an increase, frame it in terms of the value you have delivered — not just rising costs. Show the client metrics, completed work, and improvements you have driven. Most clients expect and accept modest annual increases, especially if they are satisfied with your work. If a client resists reasonable increases, it may be a sign to reconsider the relationship, as your costs and market value will continue to rise even if their budget does not.
