Monthly Budget Tracking

Track your monthly income and expenses to understand your budget.

Setup

First, add your transactions for the month:

# Add various expenses
kakei add --date 2025-01-05 --amount -1200 --category Food --account Cash --memo "Lunch"
kakei add --date 2025-01-10 --amount -3000 --category Transport --account Card --memo "Monthly pass"
kakei add --date 2025-01-12 --amount -500 --category Hobby --account Cash --memo "Book"
kakei add --date 2025-01-20 --amount -800 --category Food --account Cash --memo "Dinner"

# Add income
kakei add --date 2025-01-15 --amount 50000 --category Salary --account Bank --memo "January salary"

Group by Category

See spending breakdown by category:

kakei transform --program "(group-by table (lambda (pair) (cdr (assoc 'category (cdr pair)))))"

This shows all transactions grouped by their category, making it easy to see where your money is going.

Calculate Category Totals

While kakei's Lisp dialect doesn't have arithmetic functions yet, you can group by category and manually sum the amounts:

kakei transform --program "(group-by table (lambda (pair) (cdr (assoc 'category (cdr pair)))))"

Look at the amounts in each group to understand your spending patterns.
