Interruption does not mean zero cost
When a workflow is cut halfway through, much of the cost appears on re-entry: rebuilding context, reinjecting inputs and repeating steps that were already executed.
H-REVN™ Simulation
Workflow resume calculator
A realistic calculator to measure the cost of resuming interrupted workflows
This landing adds a more realistic lens than the aggregate simulation: it compares context reconstruction against resume from verifiable state, and distinguishes theoretical token savings from realistic savings under a monthly plan or reference budget.
Calculator
The block below reproduces the realistic V5 calculator and lets you adjust interrupted workflow parameters. It is not a guaranteed savings promise; it is an operational reading tool.
HREVN™ Trust Layer
Realistic workflow restart cost calculator
This V5 version distinguishes between theoretical token savings and a realistic reading inside a monthly plan.
If monthly savings exceed the reference plan, the excess is still valued at marginal token pricing.
Workflow parameters
Model assumption: without HREVN, an interruption forces the workflow to rebuild all context already executed up to the cut point.
With HREVN, the system resumes from the last verifiable checkpoint and only reruns the interrupted step, plus a small resume overhead.

How this widget works:
- Theoretical weekly / monthly / annual savings: calculated freely from token counts and marginal prices.
- “Plan + excess billed separately” mode: the monthly plan is used as a visible frame, but if potential savings exceed that frame, the excess is still valued at marginal token pricing.
- Not an artificial hard cap: it is a more realistic reading of how a user may continue consuming service after using what is included in a plan.
- Purpose: show context reconstruction cost without HREVN versus verifiable resume with HREVN.
The problem
The useful metric depends on the frame
In practice it helps to separate theoretical token savings from realistic savings under a monthly plan, fixed budget or additional marginal consumption.
How to read it
1. Adjust the real workflow
Enter steps, interruption point, weekly frequency and average tokenization to bring the simulation closer to your operational case.
2. Compare theory and reality
The gap between theoretical and realistic savings helps frame impact under a monthly plan, not only under marginal token pricing.
3. Read continuity, not magic
H-REVN does not invent savings where they do not exist. What changes is the resume model: verifiable checkpoint instead of blind context reconstruction.
Where H-REVN fits
This calculator does not replace a full economic analysis. It helps make one concrete point visible: when a workflow can resume from verifiable state, re-entry friction changes. That is where H-REVN adds technical value: it preserves auditable continuity across interruption, resume and downstream review.
