Short answer

SkeenaOne calculators use published Canadian government rules: the CRA's 2026 payroll formulas, the CRA's Canada Child Benefit amounts, the Department of Finance's 2026 automobile limits and the Bank of Canada's policy rate. Every page shows when its figures were last checked.

How is take-home pay calculated?

Income tax, CPP, CPP2 and EI follow the CRA's T4127 formulas for a full year of employment income in BC, Ontario and Alberta.

Credits include the basic personal amounts, base CPP, EI and the Canada employment amount. Results are estimates, not payroll advice.

How is the Canada Child Benefit estimated?

The CCB estimate applies the July 2026 to June 2027 maximums and the legislated reduction rates to 2025 adjusted family net income.

How are buying, leasing and renting compared?

Each comparison measures the net cost or the wealth left at the end of the same period, so both options are judged on equal terms.

Loan, lease, mortgage and growth rates are your inputs. The Bank of Canada policy rate is shown for context only.

How are lease amortization schedules calculated?

The lease liability is the present value of the lease payments, discounted either on exact days (actual/365, as Excel's XNPV does) or at a periodic rate of the annual rate times months per period over 12.

Under IFRS 16 and ASC 842 the right-of-use asset is the liability plus initial direct costs minus incentives; under ASPE 3065 a capital lease asset is the present value of the minimum lease payments. All lease math uses decimal arithmetic, rounded to the cent each period, so schedules close at exactly zero.
