The payback calculator compares three ways: a SaaS subscription, a Sorvelo license, and building the system yourself. Below we explain where each number comes from.
All amounts are net, and the comparison period is 3 years.
The price per user per month is the median price of 8 popular SaaS tools for resource planning with a project finance module, billed monthly, as of 11.2026.
By default the calculator uses $20 per user. You can enter the price of your own tool.
The cloud cost for Sorvelo depends on the number of employees and the provider. The table below shows the monthly cost in US dollars, without reservations, with a margin of about 44%. Prices come from public price lists, as of 11.2026.
| Number of people | AWS | Azure | Google Cloud |
|---|---|---|---|
| 25 people | $120 | $170 | $220 |
| 50 people | $120 | $170 | $220 |
| 100 people | $200 | $350 | $390 |
| 150 people | $210 | $350 | $390 |
| 200 people | $440 | $690 | $630 |
| 300 people | $720 | $1,000 | $840 |
| 400 people | $1,340 | $1,610 | $1,300 |
| 500 people | $1,350 | $1,640 | $1,340 |
The cost of building is number of people × months × cost per person. On top of that comes the cloud for the whole period: cloud × 36 months.
This is a minimum estimate. It does not include tests, fixes after launch, documentation or the risk of delays. By default we assume 1 person, 3 months and PLN 20,000 per month (about $5,405, total employer cost), and you can change everything.
All amounts are net. The Sorvelo license is a one-time cost, while SaaS and cloud are charged every month for 36 months.
