Whole-Home Automation Budget Estimator

Reviewed for 2026, updated September 8, 2026.

Estimates a planning budget for lighting control, motorized shades, and audio video zones so homeowners, architects, and builders can size a luxury automation project before requesting integrator proposals.

Luxury integration proposals rarely arrive before the floor plans are frozen, which leaves homeowners, architects, and builders guessing at an allowance during the phase when the number matters most. Without a defensible figure, automation either gets value engineered out of the plan or balloons late in construction when the walls are already closed. This estimator gives you a working budget from the counts you already know: how many lighting loads, how many windows to motorize, and how many rooms need audio or video.

The math is deliberately transparent. Each system is counted in zones or units and multiplied by an installed budget per unit that you control, so the result reflects your own assumptions rather than a hidden price list. A contingency reserve is then added on top. Treat the total as an allowance for planning conversations, not a quotation; only a written proposal from an integrator who has seen your drawings can replace it.

How to use this tool

  1. Count your lighting zones from the electrical plan, treating each separately controlled load as one zone.
  2. Enter the number of windows to motorize and the rooms that will receive audio or video, then adjust each per-unit budget to match proposals you have seen or your own expectations.
  3. Read the total planning budget and the largest line item, then use the figure as an allowance in early conversations with your architect and integrator.

What the math assumes

  • Assumes a 10 percent contingency reserve on top of the systems subtotal; it is a planning convention, not a quoted line item.
  • Assumes each per-unit budget already includes hardware, wiring, installation labor, and programming for that unit.
  • Assumes climate, security, networking, and the central control processor are either folded into your per-unit figures or budgeted separately.
  • Assumes the default per-unit figures are placeholders to be replaced with numbers from your own integrator proposals; they are not market benchmarks.
  • Assumes zones are counted as controlled loads or rooms, not as individual fixtures or speakers.

Frequently asked questions

Why does the estimator count zones instead of square feet?

Integration cost tracks the number of controlled loads, openings, and rooms far more closely than floor area. Two homes of equal size can differ by a wide margin depending on how many circuits, shades, and AV rooms the owner wants.

Does the total include the control processor and network?

Not unless you fold them into your per-unit figures. Many integrators price the processor, rack, and network as a separate infrastructure line, so ask for it explicitly when you request a proposal.

Should I keep the default per-unit budgets?

Use them only as a starting point. Replace them with figures from real proposals as soon as you have them; the tool is built so that your numbers, not ours, drive the result.
