Which results can be saved?

What Professional preserves

Three connected states, kept visible

No changed calculation is silently replaced.

Retained

Calculation version

When a saved calculation changes, its earlier version remains in the matter record.

On refresh

Calendar-feed state

A refreshed subscribed calendar feed reflects an updated date or a cancellation.

Review required

Rule-change impact

A changed rule is shown against affected saved matters for review without overwriting the saved result.

Billing questions

Which results can I save with Professional?

Professional retains completed calculations that the server can reproduce across supported jurisdictions. Provisional records stay in a review queue and cannot automatically activate calendar dates. Known incorrect results and source guides are not sold. The plan is for individual lawyers, barristers, clerks, paralegals and litigation professionals.

Why pay when calculation is free?

Free gives you the date, citation and calculation steps. Professional saves and monitors deadlines across your matters, with calendar feeds, recalculation history, rule-change warnings and exports.

What is an Evidence Record?

An Evidence Record is a one-off permanent PDF containing the inputs, result, rule ID and version, citation, calculation steps and generation time. It does not start a subscription.

No trial

No. The free calculator demonstrates the calculation itself without an account. Professional is charged when it begins and can be cancelled online any time.

How does billing currency work?

New purchases are charged in US dollars. Historical purchases keep their original terms. A calculator jurisdiction never decides your billing country or regional eligibility. Paddle confirms applicable tax and the final total before payment.

How are taxes handled?

Paddle acts as merchant of record for Paddle purchases and handles the payment, applicable sales tax, VAT or GST, and transaction documents. Checkout shows the applicable tax and final total before payment.
