What would this actually cost you?

How this is calculated. Pro model: €39.99/month with 1 TB included. Additional storage is modelled from committed +1 TB packs (€39.99/month each) and auto-scale at €7 per 100 GB-month, pro-rated daily. Protected development accounts can exercise Stripe test checkout; live charging remains disabled. Delivery is unmetered.

• Delivery is never billed — no per-download, per-recipient, or egress fees on any tier
• Auto-scale storage is pro-rated by the day; the full-month figure shown here is the worst case
• Auto-scale can be toggled off in the dashboard for a hard capacity cap

How this is calculated. Pay-as-you-go: max(0, delivered GB − 15 GB monthly credit) × $0.25 + stored GB × $0.07/month. Value subscriptions (12-month commit): cheapest tier whose allotment covers the delivered GB, plus stored GB × $0.07. The calculator shows whichever is cheaper. 1 TB = 1,024 GB.

• Billed per GB egressed — every additional download of the same file costs another $/GB (multi-recipient multiplies cost)
• Storage $0.07/GB/mo starts after 5 free days per upload, pro-rated daily
• Subscription overage rate unpublished ('preferred rate'); tiers are only applied here when the allotment fully covers delivery
• Subscriptions require 12-month commitment; allotment refreshes monthly, no rollover
• PAYG volume-tier discounts beyond flat $0.25/GB exist but boundaries are not published

How this is calculated. Cheaper of pay-as-you-go at $1.07/GB transferred (counts data in AND out — we model uploads ≈ downloads, so ×2) and committed Essentials: ceil(annual transfer TB) × $22.10/month, plus $30/TB-month for storage beyond 1 TB, plus egress beyond 10 TB/year at ≈$2.50 per overage-TB-year per month.

• Transfer commit counts BOTH directions (in and out of Aspera storage) — delivery-only modeling understates cost; we apply the ×2 default
• Deliveries out of cloud storage additionally consume the egress allowance (10 TB/yr on Essentials, then $0.03/GB)
• Essentials is feature-minimal (1 workspace); Standard Plus ($660/mo) is the realistic multi-team tier
• IBM marks prices 'indicative, may vary by country, exclude taxes'
• $0.03/GB overages assumed decimal ($30/TB); IBM does not state GB vs GiB

How this is calculated. Plan floor ÷ 12 (official "starting at" prices: Small Business $13,000/yr, Professional $25,000/yr; actual quotes scale with active users), plus your own cloud storage (≈$23/TB-month) and cloud egress (≈$90/TB delivered) paid to your cloud provider — Signiant never includes storage. Cloud-backed payload is capped (25 TB/yr on Professional); beyond the published cap: Enterprise quote.

list price + estimate · as of 2026-07

• $13,000 / $25,000 are official 'starting at' floors — actual quotes scale with active-user count (per-user rates unpublished)
• Storage is NEVER included: customer pays own on-prem or cloud storage AND the cloud provider's egress (S3 ~$23/TB-mo + ~$90/TB egress — pass-through ESTIMATE)
• Cloud-backed transfers are capped (25/100 TB per year); overage billed at an unpublished rate
• Enterprise pricing is quote-only
