Tool sources & calculation notes

Our calculators use the amounts, rates and assumptions you enter. There is no automatic statutory rate feed or hidden rate registry.

For current statutory values, use the official resources below. Each calculator explains its limits before you enter any information. Default numbers are editable examples, not recommendations; zero tax and contribution values are placeholders.

How the calculations work

Loan payments use a fixed nominal annual rate divided by 12 and equal monthly payments. Cost comparisons use undiscounted cash totals. GST / HST uses the single percentage you supply. WSIB premium estimates multiply reportable earnings by your rate per $100. Payroll and termination planners total the components you have independently confirmed.

Privacy and saving

The tools calculate locally in your browser. Entries are not transmitted to a calculation service, automatically carried into an insurance request or stored for future visits. Use Print / save PDF to keep a copy.

Checklists record your own review status. They are not audits, legal opinions, compliance certificates or insurance coverage confirmations.
