The real-numbers calculators I use myself — sales tax & remittance, pricing & margins, full landed cost, break-even, startup runway, and ROI. No signup, nothing stored.

GST / HST & remittance calculator
Add or back out sales tax for any province — then estimate what you actually owe the CRA after input tax credits.
1 · Quick tax on an amount
2 · What you owe the CRA (net remittance)
You may need to register once your worldwide taxable supplies exceed $30,000 in a single calendar quarter or over four consecutive calendar quarters. Some business types have different requirements. Confirm your situation with the CRA. The net you remit = tax you collected minus Input Tax Credits (tax you paid on expenses). See the official CRA links.
Pricing & margin calculator
See your true margin after fees and shipping — or work backwards from a target margin to the price you should charge.
Suggested price is calculated so that, after fees and shipping, your profit hits the target margin.
Landed cost & import duty calculator
The full per-unit cost of imported goods — currency conversion, freight, duty, GST, brokerage, and a suggested retail price.
Planning estimate only. GST is estimated at 5% on the duty-paid value (goods + freight + insurance + duty). Actual customs valuation depends on transaction terms, currency conversion, product classification, origin and CBSA valuation rules. Duty rates vary by HS code — confirm in the CBSA Customs Tariff. Enter the exchange rate your bank, Wise, customs broker or CBSA documentation actually uses, rather than an approximate figure.
Break-even calculator
How many units cover your costs — plus how long to earn back what you invested.
Startup cost & runway calculator
Add up one-time setup costs and monthly burn, and see the total cash you need to open and survive.
One-time setup
Monthly running costs
ROI calculator
Return on any investment — a product batch, an ad campaign, a piece of equipment.
