Estate and disability tax calculators
This is the category where a search most often ends in a form asking for your name, email and phone number before it will show you a number. There is no reason for that. The rules are published, the arithmetic is simple, and the answer belongs to you before anyone sells you a service.
Probate fee calculator
Probate tax across five provinces, compared side by side — the spread is enormous.
DTC calculator
What the DTC is worth each year — instantly, with no form to fill in first.
Retroactive DTC
Estimate a back-dated DTC claim across up to ten prior tax years.
Spousal support
The SSAG Without Child Support formula — amount range, duration, and the rule of 65.
Why every province calls this something different
Ontario charges an Estate Administration Tax. British Columbia charges a probate fee. Alberta charges a flat surrogate court fee that tops out quickly. Quebec, uniquely, charges nothing at all on a notarial will.
That naming split is why a single national probate calculator is hard to find — most tools pick one province and quietly ignore the rest. The calculator here asks which province first, then applies that province's own schedule and cites the statute or fee order behind it.
