Retainer break-even calculator — is this retainer worth taking?

A retainer is a capacity contract, not free money. See what yours actually costs.

A retainer guarantees recurring revenue, but it also commits a portion of your capacity to a single client. The question is whether the retainer pays your costs while leaving enough room for other work.

This calculator shows the hourly commitment, the break-even retainer amount, and your monthly profit at the proposed terms.

Retainers are not free money — they are a capacity contract

A retainer sounds attractive because it guarantees recurring revenue. But a retainer is also a commitment to make a portion of your capacity available to a single client for an extended period. The question is not whether the retainer pays the bills — it is whether it pays the bills while leaving enough capacity for other work.

The retainer break-even calculator answers two practical questions: how many hours of your time does this retainer consume, and what is the minimum retainer you need to cover your costs and still make a profit?

How retainer pricing differs from project pricing

Project pricing is straightforward: you estimate the hours a piece of work will take, multiply by your rate, and add a margin for risk and overhead. Retainer pricing is different because you are selling availability, not output. The client pays for the right to call on you during a defined period, and you commit to responding within agreed SLAs.

This means the value of a retainer is not measured by hours worked in a particular month — it is measured by the predictability it provides and the capacity it reserves. A $3,000/month retainer that uses only 15 hours of your time in a slow month is still valuable because those 15 hours were held for that client, not sold to someone else.

The utilisation trap

The most common mistake freelancers make with retainers is assuming that the retainer amount equals the value delivered. A $5,000/month retainer at a $150/hour rate appears to be worth 33 hours of work — but if you only have 40 available hours per month, that one retainer consumes 83% of your capacity. You cannot take on another retainer of similar size without exceeding your available time.

The break-even calculator shows the hourly commitment implied by any retainer, so you can see at a glance whether it leaves room for other work. If a retainer consumes more than 60% of your available hours, you should be charging a premium for that exclusivity.

When retainers make sense and when they do not

Retainers work best when the work is ongoing and predictable — social media management, content creation, monthly consulting, ongoing development support. They work poorly when the work is sporadic or unpredictable, because you are reserving capacity that could be sold at higher rates to other clients.

The break-even analysis helps you decide: if the retainer covers your costs and leaves a healthy profit at a reasonable hourly commitment, it is worth taking. If it barely covers costs or requires more than 100% of your capacity, it is a recipe for burnout and underpricing.
