Smart Lock Total Cost Calculator - 5-Year TCO Estimator

Calculate 5-Year Total Cost

Initial Costs

Smart Lock Price ($)

Installation Cost ($) $0 for DIY, $75-$200 for professional

Ongoing Costs

Why Calculate TCO?

A $150 lock with $5/month subscription costs more over 5 years than a $300 lock with no subscription. Total Cost of Ownership (TCO) reveals the true cost beyond the sticker price.

Hidden costs to consider:

Battery replacements: $8-$40/year depending on lock type
Subscriptions: $0-$120/year for cloud features
Professional installation: $75-$200 one-time
Replacement parts: Occasional wear items

This calculator helps you make informed decisions based on long-term value, not just upfront price.
