Model per-tenant fees, user licenses, usage charges, and growth discounts. Reveal blended unit economics clearly. Make hosting forecasts easier for every subscription scenario today.
Use this model to estimate shared platform licensing costs across tenants, users, infrastructure usage, support overhead, and taxes.
| Scenario | Tenants | Users Per Tenant | Base Fee | License Per User | Storage GB Per Tenant | Compute Units Per Tenant | Estimated Total |
|---|---|---|---|---|---|---|---|
| Starter SaaS | 8 | 25 | $900 | $11 | 80 | 35 | $4,820.64 |
| Growth Platform | 20 | 40 | $1,500 | $13 | 140 | 65 | $14,902.80 |
| Enterprise Shared Stack | 45 | 70 | $3,800 | $16 | 220 | 110 | $62,005.68 |
Total Users = Tenants × Users Per Tenant
Growth Adjusted Storage = Tenants × Storage Per Tenant × (1 + Growth Buffer ÷ 100)
Growth Adjusted Compute = Tenants × Compute Units Per Tenant × (1 + Growth Buffer ÷ 100)
Subtotal = Base Platform Fee + Tenant Admin Cost + User License Cost + Storage Cost + Compute Cost + Backup Cost + Integration Cost
Discount Amount = Subtotal × (Discount % ÷ 100)
Net After Discount = Subtotal − Discount Amount
Support Cost = Net After Discount × (Support % ÷ 100)
Contingency Cost = Net After Discount × (Contingency % ÷ 100)
Pre Tax Total = Net After Discount + Support Cost + Contingency Cost
Tax Amount = Pre Tax Total × (Tax % ÷ 100)
Grand Total = Pre Tax Total + Tax Amount
Cost Per Tenant = Grand Total ÷ Tenants
Cost Per User = Grand Total ÷ Total Users
It estimates the full shared licensing cost for a multi-tenant environment. The model includes base fees, user licenses, storage, compute, backup, integration, support, contingency, discounts, and tax.
Growth buffer increases storage and compute usage before cost totals are calculated. It helps you budget for near-term onboarding, bursts in consumption, or expected tenant expansion.
Yes. This version calculates support and contingency after discounts. That approach reflects many commercial agreements where service overhead is applied to the negotiated net amount instead of the undiscounted list price.
Yes. Set the billing cycle to annual, then enter annual prices for every cost line. The calculator will show the entered annual total and a monthly equivalent for quick comparison.
Cost per tenant helps compare customer cohorts, plan packaging, and test margin targets. It is especially useful when tenant sizes vary but you need a blended operational benchmark.
Cost per user normalizes shared platform spending across total demand. It supports seat pricing reviews, margin analysis, and negotiations with vendors or internal finance teams.
No. Enter zero for tax if you want a pre-tax estimate. The same approach works for discount, support, contingency, backup, or integration fields when those items do not apply.
Yes. Change tenant count, user density, rates, or buffers to test best-case and worst-case outcomes. The example table also gives you a simple benchmark for comparing different deployment tiers.
