Side-by-side breakdown

How to read this: 12-month TCO = setup + (monthly × 12) + estimated maintenance overhead. Risk dots reflect bus factor, ceiling risk, and maintenance burden. Winner balances cost, speed, and risk — not just lowest cost.

Let NextAutomation build it for you

Productionized templates, voice + automation stack pre-integrated, fixed scope and timeline. Most clients deploy in 2–3 weeks and pay back in <30 days. Free 30-min call — we'll tell you honestly if you should use no-code instead.

How the math works. In-house dev rate: $200/hr fully loaded (Levels.fyi US senior AI engineer median ~$180–220K base + ~30% benefits/tools/management). Baseline hours per use case calibrated on observed scope across deployed NextAutomation projects. Freelancer rates: Upwork/Toptal medians for AI engineers ($75–150/hr blended). Agency retainers: NextAutomation observed across 50+ projects. No-code platform costs: 2026 published pricing for Vapi, Synthflow, Make, Bland, and similar. Maintenance overhead defaults to 30% of build cost per year (industry rule-of-thumb for production AI agents — covers prompt tuning, edge-case handling, model updates, integration drift). Numbers are estimates; your actual costs vary by region, complexity, and quality bar. Use this to size the decision, then ground-truth with quotes.

AI Build vs Buy Calculator — FAQ

Should I build AI in-house or hire an agency?

It depends on three things: do you have senior AI engineering capacity, how complex is the use case, and how fast do you need it live? Generally: off-the-shelf use cases (simple support bots, basic automations) suit no-code. Moderate complexity with timeline pressure suits agency. Heavy customization with a dedicated AI team suits in-house. Freelancer makes sense for niche one-off builds when you can manage them.

What's the real 12-month cost of an AI project?

For a moderate-complexity AI use case (voice agent, AI SDR, support bot): no-code typically lands $15K–$30K/yr, freelancer $20K–$45K/yr (setup + retainer), in-house $80K–$180K/yr (200–400 dev hours at $200/hr loaded + 0.4 FTE ongoing), agency $35K–$70K/yr (fixed setup + retainer). The calculator computes your exact range based on your specific inputs.

Why is in-house build often more expensive than agency?

Three reasons. (1) Loaded dev rate: US senior AI engineers run ~$200/hr fully loaded (salary + benefits + tools + management). (2) Maintenance: AI agents typically cost ~30% of build cost per year to maintain. (3) Opportunity cost: that engineer isn't building your differentiated product. Agencies amortize the build across many clients, so per-project cost is lower.

Can I just use a no-code platform?

For off-the-shelf use cases (basic chatbots, simple automations), yes — no-code wins on cost and speed. But no-code has a complexity ceiling: custom CRM integrations, dynamic decision logic, multi-step workflows often hit walls. The calculator flags this as elevated risk on the no-code path when complexity is moderate or heavy.

What's the maintenance cost of an AI agent over 12 months?

Production AI agents need prompt tuning, error handling for edge cases, model updates, and integration drift fixes. Industry rule-of-thumb: 25–35% of original build cost per year for maintenance. In-house teams pay this in engineering hours; agencies build it into the retainer; no-code users absorb it as founder time. The calculator includes maintenance in 12-month TCO for all paths.

Where do the dev rate and retainer benchmarks come from?

In-house: Levels.fyi median for senior AI engineers in US tech hubs ($180–220K base + ~30% benefits/tools/management = ~$200/hr loaded). Freelancer: Upwork and Toptal medians for AI engineers ($75–150/hr blended). Agency: NextAutomation observed rates across 50+ deployed projects. No-code: 2026 published pricing for Vapi, Make, Synthflow, Bland, and similar.
