Formula and example
How it is calculated
Monthly cost = sum of monthly amounts; annual cost = monthly cost × 12
Worked example
€80 + €30 + €100 + €50 gives €260 per month and €3,120 per year.
Things to check
- Use your own payments. Country-specific allocation or billing rules are excluded. An annual settlement may differ from advance payments.
- Use one currency consistently. Examples use euros; the calculation works with any currency.
