What this result does not account for
- Results are a model, not a quotation — an institution's own figures govern.
- Every input is an assumption; change one and the answer changes with it.
- Rounding is applied only at the display layer, so totals may differ by a cent from a statement that rounds each line.
In short: $65.00 a month for 300 Mbps — $780.00 a year for the line. That runs 21.7¢ per Mbps; the 1,000-Mbps tier at this price would charge 6.5¢. Spread the $70.00 install over twelve months and the true month is $70.83. The national average runs about $75 — you're $10.00 under, and the promo clock is ticking.
Formula
per Mbps = price ÷ speed; all-in month = price + install ÷ months; year = price × 12
Broadband is priced per month and compared per Mbps, so the page runs both meters: the bill you pay and the rate each megabit charges. At the default, 300 Mbps for $65 runs 21.7¢ a Mbps while the gig tier at the same price would charge 6.5¢ — the cheapest way to buy speed is to buy more of it at once. The national average lands near $75 a month for a reliable plan (BroadbandNow 2026, $65 in New Jersey to $110 in Alaska), and the advertised rate is a 12-month costume: equipment rental adds $10-$15 and the regular price is waiting at the promo's end.
Worked Example
- Enter the monthly price and the speed tier.
- Enter the install fee and the months to spread it.
- Read the per-Mbps rate, the all-in month, and the year.
Defaults: $65.00 a month at 300 Mbps with a $70.00 install over 12 months — 21.7¢ per Mbps, $70.83 all-in, $780.00 a year.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Internet Cost Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What is the average internet bill in 2026?
About $75 a month nationwide for a reliable wired plan, with the full span running from $65 in New Jersey to nearly $110 in Alaska. Speed tiers bracket it: basic 100-Mbps plans land $30-$50, standard 300-500-Mbps plans $50-$70, and gigabit $80-$100 or more. The bill that arrives usually runs a few dollars past the advertised number once equipment and taxes ride along.
Why compare price per Mbps?
Because the adjectives are marketing and the megabit is arithmetic. At $65, a 300-Mbps plan charges 21.7¢ per Mbps while a 1,000-Mbps plan at the same price charges 6.5¢ — speed is the rare purchase that gets cheaper per unit as the box gets bigger. Two households on the same $65 are often paying wildly different per-Mbps rates.
How much speed does a home actually need?
Count the simultaneous streams, not the household: a 4K stream wants about 25 Mbps, a video call 5-10, and everything else is noise. A home running two screens and calls is comfortable at 100-300 Mbps; the gig tier pays for itself mainly in homes that push large files or carry a dozen simultaneous screens.
What hidden fees should I expect?
Equipment rental runs $10-$15 a month on most bills — often $120-$180 a year for a router you could own outright in eighteen months. Installation adds a one-time $0-$100 depending on the promo, and the post-promotional rate is the largest fee of all: the $39 teaser that renews at $80 is a $41-a-month surprise on month thirteen. Calendar the promo's end when you sign.
Can I negotiate my internet bill?
Regularly, and the retention line is the one that answers. Customers who call at promo's end routinely land the old rate or a competitor's offer price; switching between two carriers on a twelve-month cadence is the regional sport of overpaying households. The per-Mbps meter on this page is the number to quote: it turns 'please lower my bill' into 'your competitor charges 9¢ for what you charge 22¢.'
Does the price include taxes and fees?
The sticker rarely does — internet bills typically add several dollars of taxes, regulatory recovery, and broadcast-adjacent surcharges on top. Price the line here with the base rate, then read one real bill and add the difference to the monthly field. The honest budget number is the bill that arrives, not the one that was advertised.
Is fiber worth the switch?
On per-Mbps arithmetic, usually yes where it exists: fiber at $80 for a symmetric gig charges 8¢ per Mbps against cable's typical $15-25¢, and the upload half is the part cable structurally cannot match — video calls and cloud backups ride the upload side. Fiber build-out is patchwork, so the honest test is availability at your address, then the per-Mbps meter, then the promo's end date.
What about 5G home internet?
It is real broadband for $40-$60 flat, usually with no install and no equipment fee — priced off cellular capacity, so quality swings with tower congestion. At 100-200 Mbps the per-Mbps rate looks poor next to fiber but excellent next to nothing, which is often the rural alternative. Trial it against this page's meter before canceling the wire.
