Formula and example
How it is calculated
Remaining amount = income − fixed costs − variable spending − savings
Worked example
€2,500 − €1,100 − €600 − €300 leaves €500 available.
Things to check
- Use income that is actually available to spend. Divide annual bills by twelve to include them in monthly fixed costs.
- Use one currency consistently. Examples use euros; the calculation works with any currency.
