# Backup Storage Calculator

A quick capacity model for comparing managed backup plans, object storage, or a Veeam-style repository.

## 0.01 TB estimated retained

$0.00 / month0.01 TB source · 0% daily change · 1 days · 1 copy

### Monthly

$0.00

### Annual

$0.00

### 3-year

$0.00

Planning estimate only. Taxes, currency, regional pricing, discounts, commitments, support and minimums may change the final invoice.

## How this estimate works

This uses a deliberately simple model: source data × (1 + daily change rate × retention days) × repository copies. Real backup products use compression, deduplication, synthetic fulls, immutability and tiering, so measure a representative job before committing.

Pricing reference: [Veeam backup billing model](https://helpcenter.veeam.com/docs/one/userguide/backup_billing.html). Checked 2026-09-19. Prices shown in USD and may change.
