Can I add custom categories?

Yes. In addition to the preset categories (Housing, Food, Transport, etc.) you can type a custom category name and amount using the 'Add Category' button.

How is the variance percentage calculated?

Variance % = ((Actual − Budget) / Budget) × 100. A positive value means you overspent; a negative value means you came in under budget.

Budget and actual values are saved automatically in your browser's localStorage, so your data persists when you close or refresh the page.

Can I reset everything and start fresh?

Yes. Use the 'Reset' button to clear all actual spending values back to zero. Use 'Clear All' to remove all categories and start with a blank slate.

このツールについて

Set budget amounts for common spending categories such as housing, food, transport, entertainment, and more. Enter your actual spending for each category to see an instant visual comparison. A horizontal bar chart renders budget vs. actual side by side per category, colour-coded green for under budget and red for over. An overall summary shows total budget, total spent, and the variance as a percentage.
