How cash recovery is defined
Balances start at zero and include only this budget’s cash outflows and spending eliminated. Recovery is the first month-end that stays nonnegative through month 12. Recovery beyond month 12 is not modeled.
Select a month to inspect its cash spending and reclaimed hours. Reclaimed time is capacity, not cash savings.
About this example
Backup contents: Inputs, attached workflow notes, price sources, and the frozen comparison baseline. Unapplied observations are excluded. CSV exports results; restore a JSON backup to resume editing.
Compare budgets
Save a baseline, then edit this budget. The baseline keeps its original inputs and price sources.
| Metric | Saved baseline | Current case | Change |
|---|
Change = current budget minus baseline. Compare tool capabilities and workflow fit separately.
Monthly cash flow
Annual plans and setup payments are paid in month 1. Monthly costs and spending reductions stay constant. Actual invoice dates may differ.
| Month | Cash outflow | Spending eliminated | Net cash impact | Cumulative cash impact |
|---|
Cash impact is spending eliminated minus outflows. Reclaimed time does not appear as cash.
Monthly rollout assumptions
Adoption builds in equal monthly steps after the delay. Working weeks are spread evenly across the year. This schedule models your assumptions.
| Month | Modeled adoption | Active people | Reclaimed hours | Capacity value |

Sensitivity analysis: adoption and time savings
Compare modeled value at different adoption and time savings assumptions.

A $200M company’s finance workflow program
Westhaven Services Group · dataset westhaven-workflows-2026-v1 · original Finance program inputs, before your edits.
672 reclaimed hours produce $40,320 in modeled capacity against $32,360 in resource cost. The modeled surplus is $7,960, but cash does not recover within 12 months: no spending reductions are entered. Reclaimed time is capacity, not cash savings.
Worked example: inputs and cost breakdown
Forty finance and operating reporting participants, 70% adoption, 60 minutes saved per active person each week, 50% reclaimed, 48 working weeks, and $60/hour. Immediate adoption yields 672 reclaimed hours.
Forty ChatGPT Business Standard seats use the stored $20/month annual-billing rate, checked October 5, 2026. With $200 monthly usage and $5,000 setup cash, first-year cash outflow is $17,000 ($14,800 in month 1). Add 80 setup hours, two training hours per person, and eight administration hours per month: resource cost is $32,360.
Before buying, confirm your quote and measure the same task at the same output quality, including prompting, review, and rework. Replace adoption and usable-time assumptions with observed inputs. Your editable budget is calculated separately.
Calculation method

Built by Seth Sokoloff. The model separates cash spending, internal effort, and time reclaimed.
Cash cost and resource cost formulas
First-year cash cost = 12 × (monthly-equivalent subscription costs + usage + other recurring costs), plus one-time payments. Resource cost adds setup, training, and administration time valued at your hourly rate.
How time savings are valued
Full-run-rate hours = people × target adoption × weekly minutes saved ÷ 60 × active working weeks × the share reclaimed. First-year hours also apply the average monthly rollout factor: zero during the delay, then equal steps toward target adoption. Working weeks are spread evenly across the year. Capacity value = reclaimed hours × hourly value; it does not forecast earnings.
How break-even and payback work
Break-even weekly minutes cover the first-year resource cost after explicit cash savings, using the same adoption, hourly value, and realization assumptions. Simple payback divides one-time cash and effort by positive monthly net value using average first-year capacity. Rollout affects modeled time only; entered cash savings and all costs stay on their existing schedules. Smoothed cash payback uses only cash savings and outflows. Schedule-based recovery is the first nonnegative month-end after the last cumulative cash deficit in the 12-month schedule. It does not measure cash needed within a month or recovery beyond month 12.
What is saved
Inputs and baselines are saved in this browser when storage is available; budgets are not uploaded. CSV and print exports include assumptions, results, pricing sources, and the illustrative cash schedule. JSON backups also preserve the current case and frozen baseline, including attached workflow observations and price sources. Restore replaces the current draft and baseline. Reset restores the finance example and retains the baseline.
