Making a major purchase — a car, an appliance, a piece of furniture — without checking it against your actual financial situation is how people end up financially stretched. This calculator compares the cost of what you want to buy against your income, current expenses, and available savings to give you a realistic answer before you commit.
Step 1. Enter your monthly income and current expenses to establish your available monthly cash flow.
Step 2. Enter the purchase price and your available down payment.
Step 3. The calculator shows whether the purchase fits your financial situation based on how much monthly cash is available.
With the default inputs loaded in the form, the calculator produces a starting result you can use as a baseline. Change one field at a time to compare a new scenario.
The key question for any major purchase isn't just 'can I pay for it today' — it's 'can I absorb this into my monthly budget without disrupting everything else.' A $20,000 car financed over 60 months at 7% adds a $396/month payment to your budget. That's real money that comes out of savings, discretionary spending, or both.
If you're financing a purchase, the down payment is critical. Putting down 20% on a car instead of 5% significantly reduces your monthly payment and total interest paid. The calculator helps you see whether your available savings are enough to make the financing terms workable.
One honest rule for discretionary purchases: if buying it would require you to dip into your emergency fund, you can't actually afford it right now. Emergency funds are not down payment funds. Waiting an additional two to four months to save properly is almost always worth it.
Most financial advisors recommend keeping total car costs — payment, insurance, fuel, and maintenance — under 15–20% of your monthly take-home pay. The payment alone shouldn't exceed 10–12%.
No. Keep your emergency fund intact. A larger down payment is helpful, but not at the cost of leaving yourself financially vulnerable. The right balance is to put down enough to get reasonable loan terms while keeping 3–6 months of expenses in reserve.
