Not what the next guy charges. Your year, your overhead, and the hours that actually reach an invoice, divided into the number you have to quote to end up where you said you wanted to be.
Before personal income tax. What you want to pay yourself for doing the work.
Everything no single job carries: truck, fuel, insurance, phone, tools, software, accountant, licences.
Quoting, chasing payment, driving, sourcing and dead site visits are worked and not billed. Most solo contractors land between 50 and 70.
Income tax plus CPP, national insurance or self-employment tax, as a share of your pay. Leave blank to leave it out.
On top of paying you. Taken as a share of price. Leave blank if the business is just you and your wage.
Optional. Enter it and the page prices the gap.

The last field turns this from a rate into a diagnosis: what your current number actually leaves you at the end of the year, and the raise that closes the gap.

The same year needs a different rate depending on how much of your week reaches an invoice. Ten points of utilisation is worth more to you than most price rises.
It covers your hours and the business behind them. Materials, plant hire and subs are priced on top with their own markup, and the profit on those is a separate decision from the profit on your time.
Knowing the rate is what lets you quote a fixed price safely. You price the job at what it is worth to the client, and the rate is how you check the job is worth doing before you sign it.
Track the time against the job and the platform does this sum with your real hours instead of the ones you estimated on a Sunday night. Quoted against actual, job by job, so the rate that looked fine on paper gets checked by the work.
Then the quote becomes the invoice, the invoice chases itself, and your win rate against price tells you whether the number you just worked out is one the market will pay.
Markup and margin calculator
The arithmetic solo contractors lose money on. 20% markup is not a 20% margin, and this shows you the gap in dollars.
HST on holdback calculator
The HST you charge on a holdback invoice, and the part of it you do not have to remit yet. Shows both dates the deferral turns on.

Proper invoice date in. The 28 days, the 14-day dispute notice, and your own 7 days down to your subs, all dated.
