Internet is a fixed monthly cost most households never audit. 35/month plan plus 5 router rental plus 50 setup comes to 470 in year one and 2,450 over 5 years. Providers often compete hard on year-one promo rates, then raise sharply at renewal. Knowing 5-year total cost makes you a tougher customer when renewal calls come.
Quick example
With monthly plan of 35 and router rental of 5 (plus setup fee of 50), the result is 2,450.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Monthly Plan, Router Rental, and Setup Fee (one-off). Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
What's happening under the hood
Monthly costs × 60 months + one-off setup. Assumes pricing stable for 5 years, which rarely happens — treat as a baseline. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Using the result to negotiate
The figure gives you a concrete number to quote when shopping alternatives. "I'm paying £X annually" cuts through marketing in a way "I want a better deal" doesn't. The specificity wins.
What this doesn't capture
Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.
