Retainer vs Hourly Billing Calculator
Compare a monthly retainer with hourly billing and see the break-even hours and what changes if usage changes.
Retainer vs hourly: what's the difference?
A retainer is a fixed fee for a set scope of work each month, paid the same whether the work runs light or heavy. Hourly billing tracks every hour, so your pay moves with the work. A retainer trades some upside for predictable income and simpler invoicing; hourly billing protects you when a month runs long.

Reading the comparison
Below break-even hours the retainer pays more than hourly billing. Above it, hourly wins. The two scenario rows show how sensitive the deal is to the client's real usage.
When is a retainer the better deal?
When work is steady and predictable, and you'd rather have reliable income and an easier invoicing routine. It also stops the client from watching the clock on every message.
How do I protect myself on a retainer?
State the hours or deliverables it covers, what happens to extra work, and whether unused hours roll over. Without limits, a retainer can quietly turn into a discount.
What does this look like with real numbers?
At the default $3,000 monthly retainer and $75 hourly rate, break-even is 40 hours. Work 30 hours and the retainer pays $750 more than billing hourly would. Work 45 hours and hourly billing would have earned $375 more than the retainer.
