The Weekly Payment Calculation Explained"},"content":{"rendered":"

“How much is it per week?” is often the first question we get asked in front of a vehicle, and it is a good question, provided you know what payment you can actually sustain. Too many buyers start with the vehicle they like, then stretch the financing until the payment fits their budget. The reverse method pays off better, though: set your budget first, then go shopping.<\/p>\n

In this article, we give you a simple three-step method: a basic rule to set your ceiling, the list of costs the payment does not cover, and a concrete table of weekly payments by amount financed and loan term. By the end, you will know exactly what price range to target, before you even set foot in a dealership.<\/p>\n

Why think in weekly payments?<\/h2>\n

A vehicle’s listed price says little about what it will cost you each week, once the rate, the term and the down payment are factored in. The weekly payment, on the other hand, compares directly to your reality: your paycheque, your rent or mortgage, your groceries. It is also the most honest unit for comparing two vehicles, as long as you compare financing of the same length. A lower payment obtained by adding two years to the loan is not a saving, it is a deferral.<\/p>\n

The 10% rule: your starting point<\/h2>\n

A simple and widely used benchmark in personal finance is the 20\/4\/10 rule, popularized notably by the firm J.D. Power: about a 20%<\/strong> down payment, a repayment term ideally capped at 4 years<\/strong>, and vehicle payments (principal, interest and insurance) that do not exceed 10% of your net income<\/strong>, meaning the money actually deposited into your account after taxes.<\/p>\n

A concrete example: with a net income of $45,000<\/strong> a year, the rule gives a maximum of about $87 a week<\/strong> for the vehicle payment and insurance combined. It is a starting point: few debts and no dependants give you some slack, while an already tight budget calls for aiming below the bar. The 4-year term and the 20% down payment, for their part, are demanding in today’s market; we come back to that below.<\/p>\n

\"Calculating<\/p>\n

The payment is only half the story<\/h2>\n

CAA-Quebec reminds buyers of it in its purchasing guide: operating costs (fuel, maintenance, repairs, tires, parking) easily climb to a third, even half of a vehicle’s total monthly cost<\/strong>. Before setting your maximum payment, set aside part of your transportation budget for:<\/p>\n
