Cloud costs break down into compute, storage, bandwidth, and other services. Reserved instances or committed use discounts cut 20-40% off on-demand pricing. This calculator sums all components with discount.
2k compute + 500 storage + 300 bandwidth + 200 other = 3k gross monthly. At 25% reserved discount: 2,250 net monthly = 27,000 annually. Compute typically 60-75% of total spend.
Compare vs on-premise alternatives. Cloud wins for variable workloads and modest scale; on-premise can win at high steady-state scale with 3+ year horizons.
Quick example
With compute monthly of 2,000 and storage monthly of 500 (plus bandwidth monthly of 300 and other services of 200), the result is 2,250.00. 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 Compute Monthly, Storage Monthly, Bandwidth Monthly, Other Services, and Reserved Discount %. 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
Sum components. Net = gross × (1 - discount). Annual = net × 12. 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.
What the score tells you
Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
£2,000 £+£500 £+£300 £+£200 £ × 25% off = $2,250.00.
