60 annual antivirus for 5 devices = 12 per device per year. Compare to the cost of recovering from a ransomware or identity theft incident (500-5,000+). Many operating systems now include robust built-in protection (Windows Defender, macOS XProtect) that covers most threats without an additional subscription. Paid tools add features like VPN and password manager — value depends on whether you use those features.
A worked example
Try the defaults: annual subscription cost of 60, number of devices of 5. The tool returns 12.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Annual Subscription Cost and Number of Devices. 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.
The formula behind this
Annual cost divided by device count gives per-device figure. 5-year projection assumes same price. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
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.
Antivirus cost produces a per-device figure based on the inputs provided.
