Cloud storage has three cost levers: storage, egress, and operations. Storing 1TB at 0.02/GB is 20/month. Downloading that 1TB out at 0.08/GB is 80 — one egress event. For backup workloads egress rarely hits; for active workloads it can dominate the bill. Modelling both sides prevents surprises.
Run it with sensible defaults
Using storage of 1,000, storage rate per gb of 0.02, monthly egress of 100, egress rate per gb of 0.08, the calculation works out to 28.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Storage (GB), Storage Rate per GB, Monthly Egress (GB), and Egress Rate per GB — do not pull with equal force. 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.
How the math works
Storage × rate + egress × rate. Ignores operations charges (API calls) which are small for most workloads but can matter at scale. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Why run the calculation
Utility bills creep. Small annual increases stack into meaningful differences over a decade. Running this once a year and switching providers when the gap widens is one of the easiest ways to keep household costs in check.
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.
