Setting a consulting rate is where most independent professionals leave the most money on the table. The common mistake is taking a current or desired salary, dividing it by 2,080 working hours, and stopping there. That figure ignores the two realities that separate an employee from a business owner: not every hour of the year is billable, and running a practice costs money before you ever see a dollar of profit.
This consulting rate calculator works backward from the income you actually want. You tell it the net annual income you are aiming for, how many hours a year you work, what share of that time is truly billable, and what your overhead costs as a percentage of revenue. It then returns the gross revenue you need to book, the hourly rate that produces it, and the equivalent day rate you can put in a proposal. Because every input is adjustable, you can stress-test a lean year, a premium specialist position, or a full seven-figure practice in seconds.
How to Use
- Enter your Target Annual Net Income — the take-home profit you want the business to generate in a year, after overhead but before personal tax. If you are leaving a $120,000 salaried job and want to match it, start with 120,000.
- Set Total Work Hours per Year. The full-time convention is 2,080 hours (40 hours a week times 52 weeks). Adjust it upward if you plan long hours, or downward if you already know you will take serious vacation.
- Choose your Billable Time (%). This is the single most underestimated input. A new consultant often bills only 40-50% of their hours because the rest goes to prospecting, invoicing, continuing education and admin. Enter 50-60% as a realistic planning figure rather than the optimistic 100%.
- Enter your Business Overhead (%) — software subscriptions, website, professional insurance, accountant, marketing, coworking space and any subcontractor costs, expressed as a share of revenue. Thirty percent is a reasonable planning baseline; raise it if you carry staff or a large marketing budget.
- Set Billable Hours per Work Day (usually 8) so the engine can translate your hourly rate into a day rate for fixed-fee and contract proposals.
The result card shows your billable hours per year, the gross annual and monthly revenue you must book, and the highlighted required hourly rate and recommended day rate. If a client's budget comes in below those numbers, you know you are undercharging rather than closing a good deal.
The Formula Behind the Number
The math has three small steps. First, your billable hours are your total work hours multiplied by your billable utilization:
Billable hours = work hours x billable %
Second, because overhead comes out of revenue before profit, you must gross up your target income. If overhead is 30%, you only keep 70 cents of every dollar billed, so revenue must be target income divided by 0.70:
Required revenue = target income / (1 - overhead %)
Third, divide that revenue by your billable hours to get the hourly rate, then multiply by billable hours per day to get the day rate:
Hourly rate = required revenue / billable hours Day rate = hourly rate x hours per day
Worked example on the defaults: a $120,000 target with 2,080 hours at 60% billable and 30% overhead. Billable hours are 1,248. Required gross revenue is 120,000 / 0.70 = $171,429. Divided by 1,248 billable hours, the hourly rate lands at about $137.36, and an 8-hour day rate is about $1,099. Notice how much higher that is than the naive $120,000 / 2,080 = $57.69 figure most people quote — that gap is exactly the billable-time and overhead penalty consultants forget to price in.
If overhead is set to 100% or more, or billable utilization is 0%, the engine refuses to divide by zero and asks you to raise utilization or lower overhead instead of returning a nonsense rate.
Why Billable Utilization Matters So Much
Of every input, utilization is the one that moves your rate the most. Drop from 60% to 40% billable time on the same $120,000 target, and your billable hours fall from 1,248 to 832, pushing the hourly rate from $137 to about $205. That is why busy consultants who spend half their week on unpaid sales activity often feel broke despite long hours: they are working plenty, but billing too few of those hours. Treat the first few hours of every working day as sacred client delivery time, and batch prospecting and admin into the afternoon.
Examples
Example 1 — Matching a corporate salary. A marketing director leaving a $120,000 job enters 120,000 target income, 2,080 hours, 60% billable, 30% overhead, and 8 hours per day. The calculator returns roughly $137 per hour and a $1,099 day rate. She now prices project work by estimating billable hours and multiplying, rather than guessing.
Example 2 — A lean solo consultant. A career coach wants $80,000 net, works 2,080 hours but realistically bills only 50%, and keeps overhead low at 25%. Billable hours are 1,040; required revenue is $106,667; the rate comes out to about $102.56 per hour, or $821 per day. That tells her a $90-per-hour marketplace rate would actually lose money once overhead is counted.
Example 3 — A seven-figure specialist. An executive coach targeting $1,000,000 net, with 60% billable time and 30% overhead, needs about $1,145 per hour and a $9,158 day rate. That sounds extreme until you realize that at 1,248 billable hours a year, premium retainers and high-ticket group programs are the only way to reach that volume without trading time endlessly.
FAQ
How do I calculate my consulting hourly rate?
Divide your desired net annual income by (1 minus your overhead percentage) to get required gross revenue, then divide that by your billable hours per year (total work hours times your billable utilization). On the common defaults of $120,000 target, 60% billable and 30% overhead, the result is about $137 per hour.
What is a good billable utilization percentage for a consultant?
Forty to sixty percent of total work time is a realistic planning figure for independent consultants, because prospecting, admin, learning and downtime consume the rest. New consultants often start near 40%, while established specialists with steady referrals can reach 70-80%. Planning at 50-60% keeps your rate honest.
Should I charge a day rate or an hourly rate?
Use an hourly rate as your internal minimum and convert it to a day rate for client-facing proposals, which is simply hourly rate times billable hours per day (usually 8). Day rates feel simpler to buyers and protect you when a project runs long; hourly rates are transparent for open-ended advisory work. This calculator gives you both from the same target income.
Why is my calculated rate higher than my old salary divided by 2,080?
Because a salary already assumes you bill nearly every working hour and that your employer pays benefits, office costs, equipment and slow periods. As a consultant you must cover all of that yourself, and only part of your year is billable. Dividing salary by 2,080 ignores both the overhead and the non-billable hours, so it systematically undercharges you.
How much overhead should I plan for as a solo consultant?
A planning figure of 25-35% of revenue is typical for a solo practice: software, website, professional liability insurance, accounting, marketing, coworking and a small buffer for slow months. If you hire contractors or run paid ads heavily, push it toward 40% or more. The calculator grosses up your target income by whatever overhead you enter.
What day rate should a consultant charge?
Take your required hourly rate and multiply it by eight. On the standard $120,000 target that is about $1,099 per day. Premium specialists billing $1,000,000 net at the same utilization and overhead should price days near $9,000. Always set the day rate from your own numbers rather than copying a competitor, because their costs and target income differ from yours.
