What this tool answers
This page is for the question “how much can I budget for a car every month?” It does not begin with a car price. It subtracts expenses and your desired remaining buffer from take-home income.
That leftover amount has to cover fuel, insurance, maintenance, and the rest — not amortization alone. If you want the opposite direction, use Can I Afford This Car? with a specific price, or How Much Salary Do I Need? to solve for income.
Example
The form above starts with the same example: ₱85,000 take-home, ₱32,000 expenses, and a ₱10,000 desired buffer leave ₱43,000 for the car. Estimated ownership costs in this example are about ₱8,717, so about ₱34,283 remains for a loan. That leftover loan room can be turned into an estimated maximum car price of ₱1,781,209 using the assumed ₱240,000 down payment and the example interest rate.
