How Are Monthly Totals Calculated
The Overview calculates your financial totals and compares them to your budgets for a selected date range. It organizes your transactions into five categories: Income, Expenses, Investments, Savings, and Debt.
See the video tutorial explaining the Overview page here.
Overview Calculations
Step 1: Gathering Your Transactions
The system collects all your transactions within the selected date range (from start date to end date) that:
Belong to you
Are not deleted
Are categorized as Income, Expenses, Investments, Savings, or Debt. Anything categorized as Transfer is excluded from your Overview.
Step 2: Calculating Transaction Totals
For each category type, the system:
Sums up all transaction amounts in that category for the selected period (whether positive or negative)
This gives you the actual totals for:
Total Income
Total Expenses
Total Investments
Total Savings
Total Debt
Step 3: Normalizing Budget Amounts
Your budgets might be set for different time periods (weekly, fortnightly, monthly, quarterly, or yearly). The system converts all budgets to match your selected date range. To do this, it calculates the Annual total for each category, then divides this to get the Monthly amount.
For a full month period:
Weekly budgets: Multiplied by 52, then divided by 12 (to get monthly equivalent)
Fortnightly budgets: Multiplied by 26, then divided by 12 (to get monthly equivalent)
Monthly budgets: Used as-is
Quarterly budgets: Divided by 3 (to get monthly equivalent)
Yearly budgets: Divided by 12 (to get monthly equivalent)
For partial month or custom date ranges:
First, budgets are converted to monthly amounts (using the conversions above)
Then, the monthly amount is adjusted proportionally based on the number of days in your selected range
Formula:
(Monthly Budget × 12 ÷ 365.25) × Number of Days in Range
This gives you the budgeted amounts for:
Budgeted Income
Budgeted Expenses
Budgeted Investments
Budgeted Savings
Budgeted Debt
Step 4: Category Breakdown
For each category you've created, the report shows:
The category name and type
The normalized budget amount for that category (adjusted to your date range)
The total of all transactions in that category for the selected period
Example
If you select January 1-31:
Your weekly budget of $100 becomes $433.33 for the month (100 × 52 ÷ 12)
Your monthly budget of $500 stays $500
Your yearly budget of $6,000 becomes $500 for the month (6000 ÷ 12)
All transaction amounts from January are summed up
You can compare your actual totals against your normalized budgets
Notes
The system uses 365.25 days per year to account for leap years when calculating partial periods
Only transactions that are not deleted and not deleted duplicates are included
