NEW CAPABILITY 03 / 06

Engagement ROI calculator

Put in your own numbers and see when the work pays for itself.

LIVE ON THIS PAGE

You can use this right now. It runs in your browser, on this site’s own data.

Most ROI claims are someone else’s arithmetic. This one is yours: you supply the hours, the rates, and the reduction you think is realistic, and the model shows the ramp, the payback month, and how the answer moves when you are wrong.

Engagement ROI model

Put in your own numbers.

Every figure below is yours. Change any input and the model, the payback month, and the three year line redraw. Nothing you type leaves your browser, and no number here comes from a client engagement.

Your inputs

Everyone who spends real time on documents and collateral.

Time spent on documents and collateral, not the whole week.

Salary plus employer costs, not a billable rate.

Agency, contractors, and tools for the same work.

Your estimate of the work that stops being manual.

Months before the full reduction is reached.

Charged once, in month one.

Licences, hosting, and the time to keep it current.

If you are wrong about the reduction

The reduction is the input people get wrong most often, so here is the same model at five different levels. Everything else stays as you set it.

Scroll the table sideways to see all five levels.

Every assumption in this model

  • The hours saved are your estimate. They are not a measured result, and nothing on this page has been calibrated against a client engagement.
  • No client data is used anywhere in this calculator. Your inputs stay in this browser, in local storage, and are never sent to a server.
  • A month is 4.33 weeks, which is 52 weeks divided by 12.
  • The reduction you set is applied to internal hours and to outside spend at the same rate, on the assumption that both cover the same work.
  • Savings phase in linearly across the adoption ramp. With a ramp of three months, month one delivers a third of the saving, month two two thirds, and month three the full amount.
  • Hours returned are counted as money at your loaded hourly cost. That is only true if the time is genuinely redirected to other work, or if headcount actually changes.
  • Loaded hourly cost means salary plus employer costs. Using a billable rate instead will overstate the saving.
  • The one time implementation cost is charged in full in month one.
  • The ongoing monthly cost is subtracted every month from month one, including during the ramp, when the saving is still partial.
  • The model ignores taxes, financing, interest, inflation, and the time value of money. Every figure is in today's dollars.
  • Payback is the first month in which the cumulative net turns positive. The horizon is 36 months, and a case that has not paid back by then is reported as not paying back within three years.
  • Nothing here accounts for the cost of change: training time, the work that stalls during a rollout, or the projects that get harder before they get easier.

Built here, running on this page. This is arithmetic in your browser, not a forecast and not a promise. A model is only worth as much as the numbers you put into it, so treat the output as a way to test your own assumptions.

THE MECHANISM / SHOW THE SHAPE, NOT THE SOURCE

How it works.

Guardrails and gates
  1. 01Estimate

    You set every input. Nothing is prefilled from a case study.

  2. 02Ramp

    Savings phase in over the adoption months rather than starting at full value.

  3. 03Model

    Hours returned, monthly saving, payback month, and a three-year line.

  4. 04Stress

    A sensitivity strip recomputes payback at five different reduction levels.

  5. 05Take it

    Copy the summary or print the page with the assumptions attached.

WHAT IT READS

  • Your team size and hours
  • Your loaded cost and outside spend
  • The reduction you believe is achievable
  • Implementation and running costs

THE RULES IT HOLDS ITSELF TO

  • Every assumption is stated on the page
  • No number is carried over from client work
  • A case that never pays back says so plainly
  • Inputs stay in your browser
A model you drive. The output is only as good as the numbers you put in, and none of them come from a client engagement.

This is a new capability, built for this portfolio. It is not part of a client engagement, and nothing here is connected to a company’s internal system. The sample company, Apex Instruments, does not exist.
