See true costs before you commit to servers. Compare two options with detailed cost breakdowns. Plan confidently and reduce waste across every billing cycle.
| Field | Option A | Option B |
|---|---|---|
| Instances | 2 | 2 |
| Hourly compute rate | 0.09 | 0.07 |
| Hours/day × Days/month | 24 × 30 | 24 × 30 |
| Storage (GB) × rate | 200 × 0.10 | 200 × 0.09 |
| Backups (GB) × rate | 100 × 0.05 | 100 × 0.05 |
| Egress (GB) × rate | 500 × 0.08 | 500 × 0.08 |
| Support plan (monthly) | 25 | 20 |
| Monitoring (monthly) | 10 | 10 |
Server pricing is rarely just “per hour.” In bills, compute is 55–80% of monthly spend, but storage, bandwidth, and operational add‑ons decide the winner. Support plans can add 5–15% when reliability targets are strict. This calculator separates recurring charges from upfront work so you can compare like‑for‑like.
Monthly compute is calculated as hourly rate × hours per day × days per month × instance count, then adjusted by any compute discount. For a two‑instance fleet running 24×30, a $0.08/hour change shifts spend by $115.20 per month, before taxes and credits. A 30% commitment discount reduces only compute, so mixed workloads need component detail.
Block storage and snapshot retention often grow quietly. If storage is 500 GB at $0.10/GB‑month, that is $50 monthly, while 300 GB of backups at $0.05 adds $15. A 20% growth in both adds $13 monthly and compounds into annual totals.
Egress is the most volatile line item for web workloads. At 1,000 GB and $0.09/GB, bandwidth is $90 per month; doubling traffic doubles cost. Public IP fees look small, but 5 addresses at $3 each still add $15 and should be tracked. Consider CDN, WAF, or cross‑region transfer charges as custom recurring items.
The calculator applies an overall discount to the recurring subtotal, then subtracts monthly credits, and finally applies tax on the remaining amount. This order mirrors many invoices. A 10% discount on a $400 subtotal saves $40; a $25 credit saves the full $25.
Migration, setup, and commitment fees can make a cheaper monthly option look expensive in month one. Amortizing upfront totals across 12–36 months produces an “effective monthly” figure for budgeting. Use the break‑even estimate to see when recurring savings repay the upfront premium. If your contract term differs, set amortization months per option to match reality and avoid distorted ROI.
1) What is the difference between monthly recurring and effective monthly?
Monthly recurring totals recurring charges after discounts, credits, and taxes. Effective monthly adds upfront costs spread across your chosen amortization months for a truer budget view.
2) How do I model reserved commitments or savings plans?
Enter the compute discount percentage for the compute-only savings. Put any one-time commitment or prepayment in Reserved fee, then amortize it over the contract term.
3) Where do I include databases, load balancers, or security tools?
Use Custom recurring items to add monthly costs for managed databases, load balancers, CDN, WAF, logging, or support add-ons. Add one-time consulting or setup charges under Custom one-time items.
4) How should I estimate bandwidth (egress) accurately?
Use recent monitoring data for 30–90 days, then include seasonality and peak events. Enter expected GB and rate, and add separate custom lines for cross-region transfer or CDN egress if billed differently.
5) Does the calculator handle discounts, credits, and taxes correctly?
It applies an overall discount to the subtotal, subtracts monthly credits, then applies tax to the remainder. If your invoice taxes before credits, model this by reducing the credit amount to its post-tax equivalent.
6) How is the break-even month estimated?
If the cheaper monthly option has higher upfront costs, break-even months equal upfront premium divided by monthly savings. If there is no upfront premium or no recurring savings, break-even is not applicable.
