Payback — Automation ROI & Time-Saved Analyser

Payback — Automation ROI & Time-Saved Analyser — a premium, 100% offline digital tool by Aceplore. Runs entirely in your browser: no accounts, no subscriptions, your data never leaves your device.

A private, offline analyser for automation business cases — a task cut from 45 minutes to 15, run 180 times a month, saves 5,400 minutes and 90.0 hours; at a 35.00 hourly cost, less 200.00 a month to run, that is 2,950.00 net, and a 12,000 up-front comes back in 4.07 months — 31 tools in one, and it says a case never pays back rather than printing a negative month count.

31 built-in tools in one app. A candidate list with a full case page, a start-a-case form and five statuses from idea to parked; tasks carrying minutes before, minutes after, times per month and people, a task detail that works one task line by line, a time-saved view reporting the same saving in minutes AND hours, and an hours view converting to working days and full-time equivalents at conventions you set and can see; role rates that are an hourly COST you enter rather than a price, a value-of-time chain that values each task at its own rate before coverage and a realisation share are applied, and a partial-coverage page sweeping the whole range from 0 to 100% with the costs held constant; costs split across build, licence, runtime, maintenance and training with one-off and monthly kept apart, a calculator that turns build hours × an hourly cost into a one-off line, and the net-monthly subtraction; payback as up-front ÷ net monthly with the division refused when no period exists, breakeven on a running total, year one, and three years labelled a projection; sensitivity at savings levels you list and a worst case built from five pessimistic inputs you choose; error rates before and after at your own cost per error, kept out of the payback basis unless you switch it, and a total-benefit view that always shows the two halves before the sum; compare and portfolio across every candidate; plus actuals, variance against the projection, seven CSV exports, a printable one-page case and settings.

Time saved. (before − after) × times per month × people. A task at 45 minutes before and 15 after, run 180 times a month by one person, is 5,400 minutes and 90.0 hours a month — and both figures are shown, because people reason in both.

Payback. Up-front ÷ net monthly: 12,000 against 2,950.00 a month is 4.07 months. Where the net monthly is zero or below it says the case never pays back instead of printing a negative or infinite month count, and where there is no up-front cost it says so instead of dividing.

Worst case & Sensitivity. The case recomputed at the savings levels you list, and again at five pessimistic inputs you choose — saving achieved, coverage, realisation, up-front overrun and running-cost overrun. Nothing here claims what a typical overrun is.

Payback is a planning, costing and record-keeping tool for people building with AI. Every figure it reports is computed by a stated formula from the rates, sizes, counts and thresholds YOU enter. It ships no model prices, no context windows and no tokeniser: those differ by provider and model and change without notice, so you enter them and the app shows which ones it used. Where a token figure is derived from the length of a text, it is an ESTIMATE and not a count — real tokenisers are model-specific and cannot run offline. Treat every projection as a planning figure and confirm actual usage and cost against your provider's own reporting and billing before you commit to a budget. Nothing here is a guarantee of a cost, a saving, a quality level or a result, and none of it is business, financial, legal or engineering advice. You are solely responsible for your own decisions.
