Prices exclude HST. 50% deposit, balance on delivery. You own the delivered code; the underlying engine stays ours to reuse.

Most payroll teams want three of these — bonus, vacation, overtime — so the per-tool price is the one to look at.

Terms for professional use

Countworthy's calculators and the figures they produce are provided as tools, not as advice, and without warranty of any kind.

The professional using a calculator remains responsible for verifying any figure before relying on it for a client or member.

No calculator is guaranteed to fit a specific situation; nothing here overrides your own judgment or your own numbers.

To the maximum extent permitted by law, Countworthy accepts no liability for any loss arising from the use of a calculator or a figure it produces.

The code delivered for a custom build is the client's; the underlying engine, tax tables and verification pipeline remain Countworthy's to reuse elsewhere.

Under a yearly re-verification plan, sources are re-checked and rates re-indexed each January.

These terms, and any agreement between Countworthy and a client, are governed by the laws of the Province of Ontario.

Questions

Why not use our payroll vendor's calculator?

Most payroll systems run the regular pay cycle correctly and don’t need replacing for that. What they rarely have is a quick, shareable answer to the one-off question that comes up between runs: what a specific bonus nets out to before you commit to it, what a departing employee’s vacation payout should be, what a mid-year hire’s first partial cheque looks like. These calculators are built for that single question, sourced and dated, not to replace your payroll system’s own engine.

Is this specific to our province?

Bonus withholding uses CRA’s method for federal tax everywhere and for provincial tax outside Quebec, and Revenu Québec’s rules for Quebec income tax, but vacation pay and overtime thresholds are set by each province’s or territory’s employment standards act, and each calculator asks which one applies before it computes anything — Ontario’s overtime threshold isn’t British Columbia’s, and vacation entitlement schedules differ too. Every figure is cited to the act it comes from, dated, and re-checked each January.
