# What does Density Waffle cost over three years?

Density Waffle’s published room and phone-booth pricing is $279 for a sensor and $8 per sensor per month for software, billed annually. At an unchanged rate, the illustrative three-year hardware-and-software subtotal is **$567 per sensor**.

This subtotal is a planning calculation, not a quote or a complete cost of ownership. Add the costs specific to your deployment before approving a budget.

## Build the budget from two published inputs

The calculation is straightforward:

**$279 hardware + (36 months × $8 software) = $567 per sensor.**

Both inputs come from [Density's Waffle pricing](https://density.io/waffle). The $8 rate applies to rooms and phone booths on annual billing. Multiplying that monthly equivalent by 36 models three years of software; it does not mean the software is invoiced monthly.

| Budget component | One sensor | Hypothetical 50-sensor deployment |
| --- | ---: | ---: |
| Hardware | $279 | $13,950 |
| Software per year | $96 | $4,800 |
| Software across three years | $288 | $14,400 |
| Three-year hardware-and-software subtotal | **$567** | **$28,350** |

These figures exclude taxes, shipping, installation labor, power and network costs, replacement hardware, and any discounts. They assume unchanged pricing and no additional hardware purchases. Actual sensor quantities and placement need to be confirmed for your spaces. Fifty sensors is an illustration, not a recommended configuration or customer result.

## Plan the cash flow as well as the subtotal

For the same hypothetical 50-sensor deployment, hardware plus the first year of software comes to $18,750. Each subsequent year of software is $4,800 at the assumed rate. Together, those three years produce the $28,350 subtotal above.

Keeping hardware and recurring software separate helps a workplace team explain the proposal to finance. It also makes revisions easier: change the number of sensors or the planning period, then show how the budget moves. Keep excluded costs visible rather than presenting the subtotal as the entire project budget.

## Start with the spaces connected to a decision

Waffle is a self-installable radar sensor designed for spaces including meeting rooms and phone booths. It provides anonymous people count with real-time and historical occupancy data. [See the Waffle product details](https://density.io/waffle).

Choose rooms connected to an immediate question: do you need more phone booths, are small meeting rooms serving individuals or groups, or did a layout change affect usage?

Define that question before choosing the initial deployment. Your team can then connect the proposed spend to a decision and identify what it would need to learn before expanding.

## Questions to settle before ordering

### Can we multiply the sensor price by the number of rooms?

Use that as an initial scenario only. Confirm placement, coverage, power, network readiness, and the required quantity before treating the scenario as a deployment plan.

### What should a comparison include?

Use the same spaces, measurement needs, and period for each option. Include hardware, required software, installation, and ongoing operating costs. Comparing a three-year hardware-and-software subtotal with a hardware-only price would obscure the buying decision.

### How do we get a budget for our workplace?

Bring Density the rooms you want to measure, the decision you want to make, and the period you want to budget for. [Book a demo](https://demo.density.io) or email [sales@density.io](mailto:sales@density.io) to discuss Waffle for your spaces.
