How this works

The math behind your rate.

How much should I charge as a consultant?

Start from your target annual income, add your annual business expenses (insurance, software, taxes, equipment), then divide by your realistic billable hours for the year — not your total working hours. Most consultants can only bill 50–70% of a standard work week once admin, business development, and delivery overhead are accounted for. Add a profit margin on top so you're building a business, not just covering costs.

How does a consulting rate calculator work?

It divides your required revenue — target income plus business expenses — by your realistic annual billable hours, then layers a profit margin on top. The result is a minimum rate (break-even) and a recommended rate (with margin), which it also converts into a day rate and a monthly retainer figure.

What's a consulting retainer fee calculator?

It converts your hourly rate into a monthly retainer figure based on your committed billable hours, then adjusts it to reflect the discount clients typically expect in exchange for guaranteed, recurring revenue.

How do I convert my target salary into an hourly consulting rate?

Add your target salary to your annual business expenses to get your required revenue, then divide by your realistic annual billable hours — typically 50–70% of a standard work week once admin, BD, and delivery overhead are subtracted. That's your minimum rate; add a profit margin for your recommended rate.

Should I charge differently for retainer work vs. project work?

Yes. Retainer engagements usually come at a 5–15% discount off your standalone hourly rate — you're trading some margin for predictable revenue and lower BD overhead. Project-based work usually carries a 10–20% premium, since it carries more scope risk and no guaranteed follow-on work. Toggle between the two above to see the difference on your own numbers.
