What it does

Smart home setup costs balloon beyond the headline device prices because of layered extras: device hardware (smart bulbs $10-50 each, smart thermostats $200-300, video doorbells $100-300, smart locks $150-400, security cameras $50-300, smart speakers $30-300, smart switches/plugs $20-50, robot vacuum $300-1500, smart blinds $200-500 per window), installation labor (electrician for hardwired devices $80-150/hr; smart- home consultant $100-200/hr; DIY savings dramatic for plug-and-play devices), subscription services (Ring Protect $4-20/ mo, Nest Aware $6-12/mo, Apple iCloud+ $1-10/mo, Alexa Hunches $1-5/mo, smart- lock cloud features) — these stack quickly to $30-80/month for a moderate setup, which adds up to $400-1000/year forever, and ecosystem hub investment (Apple HomeKit requires a Hub like HomePod or Apple TV $100-300; Google Home / Nest is hub-included with speakers; Amazon Alexa is hub-light; Home Assistant or Hubitat for self-hosted $30-200).

The estimator takes device selections (with quantities — “6 smart bulbs, 1 thermostat, 1 video doorbell, 2 cameras”), installation preferences (DIY vs professional), and ecosystem choice (HomeKit / Alexa / Google / Home Assistant), then totals: equipment cost, installation labor estimate, monthly subscription bundle, and 3-year and 5-year total cost of ownership. The 5-year TCO is often eye-opening — a setup with $1,500 in devices and $40/mo subscriptions costs $3,900 over 5 years, with a substantial portion being recurring fees you don't notice individually.

Strategic smart-home decisions: (1) Ecosystem choice matters before device choice. Apple HomeKit: best privacy (most processing local), most reliable, highest device cost. Amazon Alexa: cheapest, widest device support, less privacy. Google Home / Nest: middle ground, good for Android households. Home Assistant / Hubitat / OpenHAB: most flexible, fully local, requires technical setup. (2) Subscription audit annually — you may be paying for cloud features you don't use; cancel them. (3) Device lifespan matters — many smart devices need cloud services to function, so when a company discontinues support (Insteon went bankrupt 2022, leaving customers with bricks), you lose your devices. Prefer devices that work locally without cloud (Matter standard, Zigbee, Z-Wave with local hub). (4) Diminishing returns past a baseline — smart locks, video doorbell, smart thermostat, a few smart bulbs / plugs are where 80% of value lives. Smart blinds, smart fridges, smart toilets are aspirational but rarely worth the cost. (5) Privacy and security — every internet-connected device is a potential attack vector. Update firmware regularly, use strong unique passwords, segment IoT devices on a separate WiFi network if possible.

How to use it

  1. Select the devices you want and quantities.
  2. Pick installation: DIY (free, your time) or professional (electrician $80-150/hr).
  3. Pick ecosystem: HomeKit / Alexa / Google / self-hosted.
  4. Read equipment total, install labor estimate, monthly subscription bundle.
  5. Check 3-year and 5-year total-cost-of-ownership for full picture.

When to use this tool

  • Planning a new home build or major renovation.
  • Deciding between brands within an ecosystem (Ecobee vs Nest vs Honeywell thermostats).
  • Comparing total cost across ecosystems (HomeKit vs Alexa vs Google vs self-hosted).
  • Annual subscription audit — what cloud services are you paying for that you don&apos;t use.
  • Pre-purchase reality check — small-feature additions can total surprisingly fast.

When not to use it

  • Highly customized professional installations (smart-home consultants for $1M+ homes) — those use specialized tools and ecosystems.
  • Apartment / rental smart home — restrictions on hardwired devices change the math.
  • Pure DIY enthusiast budgets — Home Assistant on a Raspberry Pi can dramatically lower costs but requires technical investment.
  • Specific brand pricing — list prices change quarterly; calculator uses ranges, not current promotional pricing.

Common use cases

  • Onboarding a colleague who needs the same calculation/conversion
  • Verifying a number or output before passing it on
  • Quick calculation during a typical workday
  • Pre-decision sanity-check on inputs and outputs

Frequently asked questions

Which ecosystem should I pick?
HomeKit (Apple): best privacy (most processing local), most reliable in my experience, requires Apple Hub, generally pricier devices. Alexa (Amazon): widest device support, cheapest, less privacy-focused. Google Home / Nest: middle ground, integrates well with Android. Home Assistant / Hubitat (self-hosted): most flexible, fully local, requires technical setup. For most households, pick based on phone OS — iPhone households default HomeKit; Android default Google. For privacy-conscious or technical users, Home Assistant.
How much does a basic smart home cost?
Starter setup (smart speaker + 4 smart bulbs + smart thermostat + smart plugs): $400-700 hardware, mostly DIY. Mid-tier (above + video doorbell + 2 cameras + smart lock): $1,000-1,800. Comprehensive (above + smart switches throughout + 3-4 cameras + smart blinds for 4-6 windows + ecosystem hub): $3,000-6,000. Add installation if needed: $300-1500. Subscriptions add $30-80/month forever ($400-1000/year).
Do I need professional installation?
Most smart-home devices are DIY. Smart bulbs, plugs, video doorbells (battery models), cameras (most), smart speakers, hubs — all plug-and-play. Need electrician: hardwired smart switches replacing existing wall switches, smart thermostats requiring C-wire (some installations), hardwired video doorbells, hardwired cameras with PoE. DIY savings $80-150/hour vs professional. For complex setups, a smart-home consultant ($100-200/hr) helps with ecosystem design.
What about subscriptions?
Stack up fast. Ring Protect (security camera cloud storage): $4-20/mo. Nest Aware (Google equivalent): $6-12/mo. Apple iCloud+ (HomeKit Secure Video): $1-10/mo. Eufy / Wyze etc. have free tiers but premium features cost. Smart-lock cloud features (Yale, August): $5-10/mo. Whole-home audio (Sonos, Roon): $10-15/mo. Audit annually; cancel unused services. Many cameras work locally without cloud subscription if you record to local storage.
Will my devices work in 5 years?
Maybe not. Smart-home devices depend on cloud services. When companies discontinue support, devices brick. Insteon went bankrupt 2022 leaving customers with dead devices. Wink shut down or transitioned multiple times. Even big-tech (Apple HomePod first-gen end-of-life 2021) discontinues product lines. Mitigations: prefer Matter-standard devices (cross-vendor compatibility), local-first ecosystems (Home Assistant, Hubitat), and devices with local fallback when cloud disappears.
What's the security risk?
Every internet-connected device is a potential attack vector. High-profile incidents include hacked baby monitors, compromised security cameras streaming to internet strangers, IoT botnets used in DDoS attacks (Mirai 2016). Mitigations: strong unique passwords for each device (use a password manager), enable 2FA on accounts, update firmware regularly, segment IoT on separate WiFi network if possible (most modern routers support guest networks), avoid devices from unknown manufacturers / Chinese white-label brands with poor security history. Privacy and security risks are real but manageable.
