Estimate a low–high annual cost for a managed security service from the number of users, an illustrative per-user band and your fixed yearly extras such as onboarding, a penetration test or a retainer.
Pick the bundle closest to the proposals you have, enter the number of users you will cover and add the yearly items that are not priced per user. The tool calculates: annual cost = users × annual cost per user + fixed yearly extras, once with the low end of the band and once with the high end. All amounts are ex GST; add 10% GST with the uplift and GST calculator.
The bands are illustrative only. They are monthly per-user figures × 12, chosen to show how the arithmetic works, not prices from any provider or survey. Replace them with the figures from your own written quotes. If a provider prices per endpoint, per server or per GB of logs, convert to an annual figure first and divide by your user count.
Worked example (illustrative): a 25-person office compares MDR bundles at $30–$70 per user a month, so $360–$840 per user a year. Fixed extras: onboarding $4,000, an annual external penetration test $9,000 and an incident-response retainer $5,000 = $18,000. Low = 25 × $360 + $18,000 = $27,000. High = 25 × $840 + $18,000 = $39,000, both ex GST.
Limits: the estimator does not model servers, cloud workloads or log volumes separately, renewal uplifts or price steps when you add users mid-term. Use the worked example to build those lines yourself.
