Hourly and project pricing both cap your upside at your own time: work faster or smarter and you just finish sooner for the same money. Value-based pricing breaks that link by pricing what the work is worth to the client instead of how long it took you — this calculator turns a client outcome, your share of the credit for it, and a capture rate into a recommended fee, plus the hourly rate that fee works out to so you can sanity-check it against your usual rate.
How it works
Start with the client outcome value — a real, measurable dollar figure the work is expected to move: new revenue from a launch, costs cut from a fix, hours saved by an automation. This has to be a number the client would recognize and could defend to their own boss, not a vibe.
Not all of that outcome is yours to claim. The attribution percentage is an honest discount for every other input that contributed — the client's team, their existing brand, market timing, tools you didn't build. Multiplying the outcome value by attribution gives you the value you create: the slice of the outcome that is actually attributable to your work.
The capture rate is the share of that value you charge as a fee — a well-worn heuristic in consulting puts this at roughly 10-20%, deliberately leaving the client with the large majority of the upside so the deal is obviously good for them. Multiplying value you create by the capture rate gives the recommended fee.
Finally, the calculator divides that fee by your estimated hours to produce an hourly equivalent — not because you're billing hourly, but because it's the fastest way to tell whether the fee is actually attractive relative to what you'd make on a straightforward hourly engagement.
Worked example
Say your work is expected to drive $50,000 in measurable client outcome, you're comfortable claiming 40% attribution for it, you're using a 15% capture rate, and you estimate the engagement will take 40 hours.
- Value you create: $50,000 × 40% = $20,000
- Recommended fee: $20,000 × 15% = $3,000
- Hourly equivalent: $3,000 ÷ 40 hours = $75/hour
That $75/hour equivalent is a useful gut check: if your normal hourly rate is $100, this value-based fee is actually underpricing the engagement relative to your time, and you'd be better off either raising the capture rate toward 20% or pricing it hourly instead. If your normal rate is $50/hour, the value-based fee is a clear win — the same work priced on outcome pays 50% more than pricing it on time.
How to interpret your result
The recommended fee is a starting anchor for a conversation, not a number to email a client cold. It only holds up if the client outcome value is something both sides would recognize as real and roughly correct — if you had to guess at it, the fee built on top of that guess is guessing too. Bring the assumption behind the outcome number into the conversation explicitly ("based on the $50K in reduced churn this typically prevents") so the client can push back on the input rather than just the price.
Treat the hourly equivalent as a floor check, not a target. A value-based fee that comes out lower than your standard hourly rate is a sign to either raise the capture rate, question whether the attribution share is too conservative, or walk away from value-based pricing for this particular engagement and quote it hourly or fixed-price instead. Value-based pricing is a tool for outcomes big enough to support a premium — it isn't a mandate to use it on every job.
Methodology & sources
The formula is valueYouCreate = clientOutcomeValue × attributionPercent / 100; recommendedFee = valueYouCreate × captureRatePercent / 100; hourlyEquivalent = recommendedFee / estimatedHours (zero when estimated hours is zero). Every output rounds from unrounded intermediate math, so the three figures stay internally consistent with each other.
Value-based pricing only works when there is a genuinely quantifiable outcome behind it — the calculator can't manufacture that number for you, and forcing a fee onto a vague or unmeasurable outcome tends to produce a price a client can't justify internally, which kills the deal instead of growing it. Building a fee from a quantified client outcome, rather than from hours worked, is standard advice in the consulting world; see Consulting Success's guide to value-based pricing for a fuller walkthrough of building that outcome number, including how to size intangible value and phase fees across longer engagements. The 10-20% capture-rate range used here is a separate, widely cited rule of thumb across freelance and consulting pricing guides — that source itself points toward fees sized as a multiple of ROI delivered (often landing in a similar ballpark) rather than stating a 10-20% figure directly, so treat the range as a common starting anchor to adjust for your own risk and leverage, not a number pulled from any single source.
