Uses analyzeSpendingHabits with Korean spending categories, national average category ratios, 50/30/20 budget-rule analysis, saving-intensity simulation, and compound investment projection. This English finance calculator calls the same Korean pure calculation module as the Korean page. KRW amounts, Korean thresholds, insurance rules, tax logic, and scenario assumptions are preserved instead of the old generic percentage stub.

Spending habit analysis guide

This English guide translates the Korean spending habit analyzer. The calculator calls analyzeSpendingHabits with Korean spending categories, average ratios, 50/30/20 rule, saving simulation, and investment projection.

Savings rate and spending type

The model starts from monthly income, category spending, and current savings in manwon units. It calculates total spending, savings rate, and spending type from the Korean spending-type thresholds.

Category analysis compares each category with national average ratio assumptions and highlights top overspending items. The page is therefore diagnostic, not just a pie chart.

50/30/20 budget rule

The Korean page groups spending into needs, wants, and savings and compares actual ratios with the 50/30/20 budget rule. It reports target amount, actual amount, and gap for each group.

This helps separate unavoidable fixed costs from discretionary spending. A high housing or education ratio needs a different action than high shopping or subscription spending.

Saving and investment simulation

Saving intensity changes how aggressively overspending categories are reduced. The calculator then converts monthly saving into yearly saving and investment projections using the selected return scenario.

The projection is not a guarantee. It is a disciplined way to show how small recurring changes can compound over long periods.
