TCO calculator
Two scenarios, one horizon, one honest sum. Load the 24-month example (A 23,000 vs B 27,600 USD), then replace it with your numbers. No prices are fetched; the assumptions are yours.
Accepted number format: digits with optional decimal mark. Both 1,234.56 and 1.234,56 parse to the same value; the rightmost separator wins.
The example, worked
| Field | A | B |
|---|---|---|
| Setup | 10,000 | 5,000 |
| Monthly infra | 200 | 400 |
| Monthly license | 100 | 200 |
| Maint hours/mo | 4 | 6 |
| Hourly cost | 50 | 50 |
| Exit | 1,000 | 1,000 |
| Horizon | 24 months | 24 months |
| Monthly total | 500 | 900 |
| TCO | 23,000 | 27,600 |
Fictional figures in USD, not market quotes. Under these assumptions A is 4,600 lower in total cost, which says nothing about performance or quality. The formula, its limits and the same example live on the TCO meaning page.
CSV export prefixes risky leading characters so spreadsheet apps never execute your scenario names as formulas. Nominal model only: no tax, conversion, inflation, discounting or outage probability.

Frequently asked questions
Which formula does the calculator use?
TCO = setup + months x (monthly infra + monthly license + monthly maint hours x hourly cost + other monthly) + exit. Money is computed in integer minor units with half-up rounding, so the rows reconcile with the total.
What does the worked example show?
The guide's fixture over 24 months: A totals 23,000 USD, B totals 27,600 USD, a 4,600 difference under those assumptions. It never claims A is the better product.
Does switching currency convert my numbers?
No. USD, EUR and TRY are display labels only; amounts never move with the label. Enter the figures in the currency you mean.
Are my cost figures sent anywhere?
No. All math runs in your browser and saving is opt-in on this device. Events carry the tool ID and locale, never your numbers.
