Fixed Cost

Accounting

A fixed cost is a business expense that stays the same regardless of how much you produce or sell, such as rent, insurance and salaried wages.

Fixed costs do not change with output in the short term, you pay the same rent whether you sell one unit or a thousand. They contrast with variable costs, which rise and fall with production. Most overhead is fixed, while materials and hourly labour tend to be variable.

The mix of fixed and variable costs drives a business's break-even point and its risk profile. High fixed costs mean higher break-even but greater profit once past it (operating leverage); low fixed costs mean a lower break-even but thinner upside per sale.

Example

A bakery pays $4,000 monthly rent (fixed) regardless of how much bread it sells, while flour and packaging (variable) rise with each loaf produced. Together they determine how many loaves it must sell to break even.

Multiply the pre-tax price by the combined rate for the province where the supply is made, then add that amount to the price. If the price already includes tax, divide the total by one plus the rate to get the pre-tax amount, and the difference is the tax. The rate depends on the province of supply rather than where your business sits, so verify the current rate for that province and confirm the item is not zero-rated or exempt.

Most enquiries are settled without a phone call in My Account, My Business Account or Represent a Client, where assessments, balances, slips and CRA mail all sit. When you need a person, use the enquiries line for your programme from the contact page on canada.ca, and have your social insurance or business number plus a figure from a recent return ready for identity checks. Written enquiries go to the tax centre named on your notice of assessment.

The spouse or common-law partner amount is a non-refundable credit you claim when you support a spouse whose own net income is low. The claim starts at a set base amount and is reduced dollar for dollar by your spouse net income, so it disappears once their income passes that level. Its cash value is the claim multiplied by the lowest tax rate, federally and again provincially. Take the current base amount from the federal schedule for the year you are filing.

Property tax is municipal. Your city, town or rural municipality sets the annual rate and issues the bill, inside a framework the province sets: provinces create municipalities, run the assessment bodies that value properties, and add the education or school-support levy that appears on the same bill. The federal government has no role in property tax at all, so neither the CRA nor your income tax return is where a property tax dispute is settled. The municipality is.
