Outputs explained

Output What it means
Recommended price per GB-month A money value based on your selected currency.
Recommended monthly price A money value based on your selected currency.
Estimated monthly cost A money value based on your selected currency.
Gross margin A percentage value derived from the inputs.

How it works

  • Monthly cost = (avg GB stored x cost per GB-month) + fixed overhead.
  • Recommended monthly price = monthly cost / (1 - target margin).
  • Recommended price per GB-month = recommended monthly price / avg GB stored.

Modeling tips

  • Use average GB-month stored, not peak storage snapshots.
  • Include replication or backup overhead in cost per GB-month.
  • Put support and monitoring costs in fixed overhead.
  • If request costs are meaningful, model them separately and add them into fixed cost.
  • Validate the target margin against your storage product gross margin goals.
  • Use billing exports to verify average stored GB.

Validation checks

  • Recommended price per GB-month should exceed cost per GB-month at your target margin.
  • Monthly cost should scale linearly with average GB stored.
  • If average GB stored doubles, recommended monthly price should roughly double.
  • Effective price per GB-month should exceed cost per GB-month.

Common mistakes

  • Using peak storage instead of average GB-month.
  • Ignoring replication, backup, or encryption overhead.
  • Forgetting fixed overhead at low usage volumes.
  • Mixing request costs into GB-month without modeling them.
  • Using list price storage costs instead of blended rates.

Interpretation

  • Use the recommended price as the variable storage rate.
  • Add a base fee when fixed overhead is a big share of cost.
  • If costs differ by tier, separate hot and cold storage pricing.
  • Use scenarios to pick simple, defensible tier breakpoints.

Use cases

Storage add-on
Set a per GB-month rate for storage capacity add-ons.
Archive tier
Price a low-cost archive tier with minimal access costs.

Mini walkthroughs

GB-month pricing
  1. Enter average GB stored and cost per GB-month.
  2. Add fixed overhead and margin target.
  3. Use the recommended price per GB-month.
Low usage check
  1. Set a low average GB value.
  2. Review the recommended monthly price.
  3. Decide if a base fee is required.

Scenarios

Small storage plan
100 GB average stored to test a starter storage add-on.
Large storage plan
1 TB average stored to validate enterprise storage pricing.
Replication overhead
Increase cost per GB-month to reflect multi-region replication.
Low usage plan
Low GB stored to see if a base fee is needed to cover fixed costs.

Edge cases

  • If average GB stored is 0, the model will not produce a meaningful price.
  • If cost per GB-month is 0, verify whether storage costs are included elsewhere.
  • If fixed overhead dominates, consider a base fee plus per-GB pricing.
  • If target margin is near 0, recommended price will be close to cost.

FAQ

When should I use this instead of the storage cost calculator?
Use this when you already know the storage cost structure and need a publishable GB-month benchmark rather than a deeper cost breakdown.
Is this the same as cloud storage price?
No. This estimates your selling price based on your costs and target margin.
Should I include request costs?
If your workload has heavy requests, include them via the storage cost calculator or add them to fixed overhead.
What unit should I show on my pricing page?
GB-month is common because it reflects storage over time. Add an example workload so buyers can estimate their bill.
How do I handle minimum fees?
Add a base fee and keep GB-month as the variable component. This protects margin at low usage.
Should I charge for replication separately?
If replication is optional, consider a premium tier or add-on; otherwise include it in your cost per GB-month.
