Deadline Engine review
A free legal deadline calculator with paid case management and calendar features.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Deadline Engine is a web-based legal deadline calculator for solicitors, barristers, paralegals, compliance professionals and other individual legal practitioners. It calculates procedural deadlines from encoded court, tribunal and regulatory rules, then displays citations and calculation steps for review. The free calculator requires no account or payment card and supports deadline calculations without saved case management. Its focus is individual legal work rather than a broad practice-management suite.
Pricing is structured around a free calculator and Professional access. The Free calculator costs $0 per user monthly and includes calculations, citations and visible working. Professional monthly costs $29.99 per user per month, while Professional annual costs $299.99 per user per year. Both Professional plans add eligible saved calculations in cases, unlimited cases and calculation records, calculation history, calendar feeds and exports, and rule-change impact warnings. Evidence Record is a separate $19.99 one-time option that provides a permanent PDF containing inputs, the result, citation and calculation working, with no subscription required.
The product’s main strength is the depth around deadline calculation: case timelines can include manual and court-order dates, calculation versions can be reviewed, and downloadable ICS exports support one-way calendar syncing. It covers multiple jurisdictions and procedural areas, but its platform coverage is web-only and its integrations are limited. Users must verify every calculated deadline against current rules, orders and case facts before relying on it. Deadline Engine suits solo practitioners who need a free calculation starting point or a focused paid record of deadline work; teams seeking broader platform coverage or extensive integrations should consider an alternative.
