Automation Payback Calculator: Build vs Buy vs Hire (2026)

Methodology
Every option is scored on the same total monthly cost: cash out of pocket plus the value of whatever share of the task you still do yourself, measured against keeping it manual. The break-even month is the one-time cost divided by the net monthly saving, rounded up; a month is 4.345 weeks. Failure rates, rework, and taxes aren't modeled. When a tiny task or judgment-heavy work means automating loses, the calculator says so.
Default assumptions
Defaults marked ⚠ are editable starting points, not cited facts — adjust them to your situation.
| Assumption | Default | Note |
|---|---|---|
| Hours/week on the task | 5 hrs | A UI default — replace it with your real number. |
| Hourly value of your time | $40/hr ⚠ | Roughly the all-in value of an hour of a US small-business owner's time. An anchor, not a citation — your opportunity value is probably different. Edit it. |
| DIY platform subscription | $29/mo | Defaults to Rills Hobby; edit it to model any tool's subscription. |
| DIY setup effort | 8 hrs (one-time) ⚠ | Hours to build and configure the automation yourself, valued at your hourly rate. |
| Agency build (one-time) | $2,500 ⚠ | A typical small-automation build by a freelancer or agency. Real quotes range roughly $800–$8,000+ — get one and plug it in. |
| Agency maintenance | $150/mo ⚠ | Optional ongoing retainer. Many builds run at $0 — set it to whatever you negotiated. |
| VA hourly rate | $12/hr ⚠ | An offshore VA market anchor; the real range is roughly $6–$25+ depending on skills and region. |
| VA loading multiplier | 1× ⚠ | Optional benefits/overhead burden for the employee case. 1.0 models a pure contractor. |
| Share of task removed | 90% DIY · 85% agency · 100% hire ⚠ | DIY edges out an agency build over time: a platform you tune yourself keeps improving, while a fixed build waits on the agency every time the task drifts. |
| Analysis horizon | 36 months | Fixed window; 1-, 2-, and 3-year cumulative savings are reported. |
Frequently asked questions
How do I calculate automation ROI?
Value the hours the task takes (hours per week × what your hour is worth), then subtract what each option costs per month — subscription or wages plus the value of whatever share of the task you still do yourself. Divide any one-time setup cost by that net monthly saving and you get the break-even month. Everything after that month is savings.
Is it cheaper to build or buy automation?
For most solo operators, buying (a subscription platform you configure yourself) wins: the one-time cost is just your setup hours, and you can keep tuning the workflow yourself as the task changes. A custom agency build has to clear its build fee first, and every adjustment waits on someone else's calendar, so the share of the task it removes tends to drift down over time. Run your own numbers — the crossover is visible on the timeline.
When does hiring a VA beat automating?
When the work needs human judgment that automation can only partially remove, and the person's hourly rate is below the value of your time. Someone cheaper than you who takes 100% of the task off your plate often beats an automation that only removes 60% of it.
What's a realistic agency build cost?
Small single-workflow automations typically quote in the $800–$8,000+ range depending on complexity and integrations, sometimes with a monthly maintenance retainer on top. The calculator defaults to $2,500 as a typical starting point — replace it with a real quote for your task.
How long until automation pays for itself?
For a typical 5-hours-a-week task valued at $40/hr, a $29/month tool that takes 8 hours to set up and removes 90% of the work pays for itself in the first month. Tiny tasks may never pay back — the calculator will tell you honestly, including when keeping it manual wins.
