Retainer or Hourly — Which Should You Choose?
A flat monthly retainer can sound appealing for its predictability, but it only pays off if the included hours and fee actually line up with what you'd earn billing hourly. This retainer vs. hourly comparison calculator does the math so you're not guessing.
💡 Quick Summary
Effective Retainer Rate = Retainer Fee ÷ Included Hours. If that's below your standard hourly rate, you're likely underpaid by the retainer — unless the predictability or reduced admin work is worth the trade-off to you.
Pros and Cons of Each Model
| Model | Pros | Cons |
|---|---|---|
| Retainer | Predictable income, less invoicing admin, often signals a stable long-term relationship | Risk of scope creep eating into your effective rate if hours run over |
| Hourly | You're paid for every hour worked, no risk of under-billing | Less predictable income, more invoicing overhead, clients may scrutinize hours |
Watch for Scope Creep
A retainer that looks fair on paper can quietly become underpaid work if the client's actual monthly requests consistently exceed the included hours. If you're on retainer, track your actual hours worked each month against the included hours to catch this early.
How This Calculator Works
It compares your monthly hourly-billing total (rate × expected hours) against the proposed retainer fee, and calculates the retainer's effective hourly rate (retainer ÷ included hours) so you can see directly whether it beats, matches, or falls short of your standard rate.
