Worked example
These are demonstration assumptions, not market data or a recommendation. Use Reset example above to reproduce this result, then replace the values for your own scenario.

- Alternative
- 12 USD
- Idle
- 4 months
Example result: 800 USD
The example is fixed while your live result above changes. Differences in display rounding do not change the underlying calculation.
How to use
Start with the most uncertain input
Compare three scenarios
Compare conservative, baseline, and optimistic cases instead of treating one result as a forecast.
Save and verify
Save the assumptions and update them when measured data becomes available.
About this calculation
How is this calculated?
Estimate = max(monthly fee × 12 − uses per month × 12 × alternative price, 0) + idle months × monthly fee.
What does this estimate exclude?
The idle-month term is an additional scenario penalty and may overlap with the annual comparison. Do not treat the result as an exact amount recoverable by cancelling.
