Internet equipment cost check

Modem rental vs buying your own: compare the full cost first

Checked October 31, 2026 · Equipment rules, compatibility, and prices vary by provider and plan.

Owning a modem or gateway can cost less over time when a provider charges a separate equipment rental fee and allows a compatible customer-owned device. It is not an automatic saving: some plans include equipment, some devices are not supported, and setup or replacement costs can change the result.

Before buying: Ask your provider to confirm the exact device model is supported on your plan and at your address. Check activation, service, return, and support terms in writing.

Compare rental with the costs of owning

Enter the equipment rental charge that is separate from your internet plan, then compare it with the tax-inclusive purchase price and the setup or replacement costs you expect during the same period. The calculator runs in your browser; it does not save or send your entries.

Enter 0 if equipment is included or there is no separate rental fee.
Use the full price including sales tax and required accessories.
Include provider activation, shipping, or installation charges.
Optional: expected replacement or support costs not included above.

What to check before you compare

  1. Separate the modem, router, and gateway. A modem connects to the provider’s network; a router shares the connection around the home. A gateway combines functions. Confirm which device and functions your plan needs.
  2. Confirm compatibility, not just the brand. Give the provider the model number and ask whether it is approved for your plan, speed tier, and service address. Ask whether using your own device affects any discount, support, or replacement policy.
  3. Use the plan’s Broadband Facts label. The FCC says labels show key plan information such as monthly price, introductory and post-introductory rates, and additional charges and terms. Check the label and the provider’s full terms; taxes and location-specific charges may still require confirmation.
  4. Count all ownership costs. Include the device price, tax, shipping, activation, installation, any required add-on, and a realistic replacement cost over the time you expect to keep it.
  5. Check the return deadline. If you stop renting, ask how and when to return the provider’s equipment and keep the receipt or tracking record.

Example only

Suppose a plan separately rents equipment for $15 a month. Over 24 months, that rental totals $360. If a compatible device costs $180 and setup costs $25, owning costs $205 for that period, leaving a hypothetical $155 difference before any omitted taxes, replacement expense, service-plan change, or other fees. These are sample numbers, not a current provider offer.

If equipment is included at no extra charge, or if buying it makes you lose a plan discount, buying may not lower your total bill. Compare the all-in service cost as well as the equipment line.
