Tracking Expenses Weekly, Monthly, Yearly.

Tracking expenses on a regular basis is a smart financial habit that can help you manage your finances effectively. Here's how you can track your expenses on a weekly, monthly, and yearly basis:

1. **Weekly Expense Tracking**:

- Keep a dedicated notebook, spreadsheet, or use an expense tracking app to record all your expenses throughout the week.

- Categorize your expenses such as groceries, utilities, transportation, dining out, entertainment, etc.

- At the end of each week, review your expenses and calculate the total spent in each category.

- Identify any areas where you may have overspent and look for ways to adjust your budget for the following week.

- Personally i use excel / libreOffice to track my expenses weekly. It is easy to split and do sum of the expenses. For a single person living in a hdb 3 room / 4 room flat. The typical fixed expenses will be Food / Town Council Charges / Electricity / Water / Gas (if you cook) / Handphone / Broadband / Transportation. Considering all these, it is estimated to be around $1,200 per month whereby it will be around $300 weekly. From the weekly tracking, you will be able to determine the monthly spending.

2. **Monthly Expense Tracking**:

- Compile all the weekly expense data into a monthly summary.

- Calculate the total expenses for each category for the entire month.

- Compare your actual spending against your budgeted amounts to see if you stayed within your financial goals.

- Analyze any trends or patterns in your spending habits, such as recurring expenses or areas where you consistently overspend.

- Adjust your budget for the upcoming month based on your findings.

- The reason why you need to track monthly where you already have weekly as taxes (property tax, income tax), insurance premiums will only be deducted certain times in the year. For taxes it is good to repay by monthly instead of yearly as it is interest free. For insurance premiums it will be better to pay yearly than monthly as you save on the transaction fees and you have savings. For netflix, disney, amazon, apple subscription, if you would like to have some savings, it make sense to pay yearly than monthly. But if you are trying out the subscription, it make sense to do monthly to see whether you like the shows enought for a yearly subscription.  

3. **Yearly Expense Tracking**:

- Aggregate the monthly expense summaries to create a comprehensive overview of your spending for the year.

- Identify major expenses that occurred throughout the year, such as annual subscriptions, insurance premiums, or tax payments.

- Review your overall financial health by comparing your total expenses to your total income for the year.

Tools like budgeting apps, spreadsheets, or even just a pen and paper can be useful for tracking expenses at each interval. The key is consistency and regular review to ensure you're staying on track with your financial objectives.
