Kakei: The Art of Budgeting

Inspired by Japanese Kakeibo: mindfully track your spending, understand where your money goes. Finally take back control.

Kakei reimagines budget management with the wisdom of Kakeibo, a century-old Japanese method created in 1904.

THE PRINCIPLE IS SIMPLE Mindfully writing down each expense changes your relationship with money. No automatic bank sync, no algorithms deciding for you. Just you and your budget.

HOW IT WORKS

1. Set up your situation Enter your income, fixed expenses, and savings goal. Kakei calculates your "spending budget" — the money available for daily expenses.
2. Track your spending Log each purchase in 10 seconds. The act of writing creates awareness. This is the heart of the Kakeibo method.
3. Understand and improve At month's end, see where your money went. Identify habits to change. Improve every month.

THE 4 KAKEIBO QUESTIONS

• How much money do I have available?
• How much would I like to save?
• How much am I spending?
• How can I improve?
