What Are Fixed Expenses?

The fixed costs are known in advance, and is an average cost that is fixed for each month. It is the subscription fee that you need to pay every month, like your online streaming platform fees to monthly house rent / EMI to grocery costs.

Examples of Fixed Expenses:

Rent or mortgage payments
Loan EMIs (Equated Monthly Instalments)
Insurance premiums
Subscription services like Netflix or Amazon Prime
Provisionals with constant rates (e.g., internet or phone charges).

Key Feature: Short-run fixed costs are non-adjustable in the short run but also may be changed even in the long run (e.g., re-financing loan or loss of dwelling).

What Are Variable Expenses?

Variable expenses are, of course, a function of lifecycle decisions, consumption patterns and/or unforeseen situations. These charges may be made higher or lower, to correspond with the financial capability.

Examples of Variable Expenses:

Groceries and dining out
Transportation (fuel, or public transport)
Entertainment and hobbies
Clothing and accessories

E.g., billing for an electric service rate (e.g., number of accounts) or water rate, etc.

Key Feature: Variable costs are as well elastic (i.e., they are probably the areas where the most savings are possible) and hence it is in their zones where the highest possibility of savings will be found in the best variant.

Why Distinguish Between Fixed and Variable Expenses?

The difference between fixed and variable costs allows you to plan your month ahead, therby estimating your costs. If you are short on savings, variable costs can be adjusted to account for saving shortfall as fixed costs are rigid and cannot be reduced.

Budget Allocation: Aids categorization of the extent of income made allocation versus allocative commitment.

Flexibility: Identifies where you can adjust spending to save more.

Financial Health: Focuses on the places in which runaway spending and under – estimation of costs may happen.

Identifying Financial Leaks

Financial leaks can be identified via fluctuation of the costs by analysing monthly expenditure of previous months. Here’s how to spot and plug them:

Review Your Spending Habits

Analyse your spending over the last 3–6 months. Look for patterns in both fixed and variable expenses.

Are you paying for subscriptions you no longer use?

Is it my own excess electricity usage that is causing my electricity bill to be abnormally high?

Solution: In terms of the cost of utility consumption, On the one hand, you can use required amount and not waste to save utility consumption cost while on the other hand cutting down the extra services and associated payments that you don’t need can save few bucks.

Compare Costs Across Providers

In the case of fixed costs, e.g., insurance or internet, the situation may actually involve overpaying.

Are there better deals or discounts available?

Can you renegotiate rates with your current provider?

Solution: Regularize the process of searching for the highest possible rates to achieve discounts or subscription type services.

Track Impulse Purchases

Variable costs, e.g., eating out or buying via the internet, are repeat offenders.

Are you purchasing things you don’t particularly want and don’t need, opting for frequent purchases?

Small and regular purchases add up to a considerable amount of cash, right?

Solution: Cash budgets, or spending limits, on credit cards should never be overshot.

Plan for Irregular Expenses

There are also certain variable costs, like car maintenance or medical expenses, for which the presence might actually upset your budget in the case of an unexpected event.

Solution: Save some of your income in an emergency fund to account for these unforeseen expenses.

Audit Your Utility and Usage-Based Bills

Variable utilities (e.g., within the power or water field) may provide a measure of inefficiency.

Solution: Energy-saving behaviours, such as switching out incandescent bulbs/LEDs, or taking steps to address leaky faucets, etc.

Set Spending Goals

Establish realistic caps for your variable expenses. For example:

Limit dining out to ₹2,000 per month.

Allocate ₹5,000 for monthly transportation costs.

Tip: Budgeting apps or spreadsheets are to be used to record expenses and to monitor such restrictions.

Balancing Fixed and Variable Expenses

The 50/30/20 Rule is a debt management technique, which may help to achieve balanced budget.

50%: Fixed expenses like rent and EMIs.

30%: Variable expenses for lifestyle choices.

20%: Savings and debt repayment.

Adapt the proportions according to your means and objectives.

Conclusion

Provided that the “fixed” inflexibility of the fixed and the “variable” flexibility of the variable have a recognizable definition, one can go on to aim for a higher degree of control over financing and identify the “weak” core that needs attention. These costs can be serialised, enabling the computation of financial loss and may be saved or capitalized for investment purposes. As a beginner, to get an idea of how much people are putting their money toward today, in turn, raise that first step to becoming financially free.
