Expense list

Add what you actually pay

Method

Every expense is converted to an annual amount first.

This avoids treating a €720 bill paid twice per year as €720 per month. Finance Charts annualises each row, adds the totals, then divides by 12.

Weeklyamount × 52 ÷ 12
Every two weeksamount × 26 ÷ 12
Quarterlyamount × 4 ÷ 12
Twice yearlyamount × 2 ÷ 12

Interpretation

Essential and discretionary are planning labels, not universal categories.

Mark a cost essential when it would remain necessary during an income disruption. The choice depends on your household. A car may be essential for one person and optional for another.

Your essential monthly result can feed the emergency-fund model without creating a universal recommendation.
