Before you can map out a route to a destination, you need to know your starting point. The same is true for your finances. Saving for a big goal like a down payment begins with a clear, honest look at your current financial situation. This isn't about judgment; it's about gathering facts. Let's walk through how to get a complete picture of your money.

First, figure out exactly how much money you bring in each month. The key here is to use your take-home pay—the amount that actually lands in your bank account after taxes and other deductions like health insurance or retirement contributions. Your payslip is the best source for this.

Don't forget to include income from all sources. This could be a primary job, a side hustle, freelance work, or any other regular cash flow. Add it all up to get your total monthly income.

Next, you need to know where your money is going. This means tracking all of your monthly expenses. It helps to divide them into two categories: fixed and variable.

Fixed expenses are the predictable costs that stay the same each month. Think of things like rent or mortgage payments, car payments, and insurance premiums.

Variable expenses are costs that change from month to month. This category includes groceries, gas for your car, dining out, and entertainment. These are often the areas where you have the most flexibility to make changes later.

To get an accurate picture, review your bank and credit card statements from the last two or three months. This will give you a realistic average for your variable spending. Don't just guess—the actual numbers can be surprising.

Now for the moment of truth. Your net income (or discretionary income) is what's left after you subtract your total expenses from your total income. This is the money you have available for saving, investing, or extra debt payments.

Using our example figures, the calculation is straightforward:

This $900 is the starting point. It's the amount you could potentially put toward your down payment each month without changing anything.

The final part of your financial snapshot is a look at your existing savings and debts. This gives you a broader view of your overall financial health.

First, take stock of your savings. How much cash do you have on hand in checking, savings, or other easily accessible accounts? This is your starting block for a down payment fund.

Next, list all your debts. This includes credit card balances, student loans, car loans, and any personal loans. For each debt, note the total amount owed and the interest rate. High-interest debt, like from a credit card, can significantly slow down your ability to save.

With this complete picture—your income, expenses, savings, and debts—you now have the foundation you need. You've replaced assumptions with facts, which is the essential first step toward reaching your goal.
