One auditable, purpose-built system for the whole depreciation study — replacing sprawling spreadsheets and one-off scripts, so analysts spend less time wrangling data and more on judgment.
Utilities, state and federal commissions, and industry consultants use Depreciation Workbench to calculate rates, forecast service life, and stand behind the result.
Replacing sprawling spreadsheets and one-off scripts with a single auditable system for the whole study.
Import continuing property records and reserve balances from any source, then validate against control totals before a single number is calculated.
Roll parent and child accounts together with flexible per-group consolidation rules, so studies mirror your chart of accounts and rate presentation.
Compute accrual, reserve, and remaining-life results with an auditable engine that keeps every study fully reproducible.
Fit survivor curves to historical retirement experience, score the fit, and stress-test life estimates interactively.
Generate a full suite of study reports with saved, shareable views and formatting built for regulatory filings.
Track studies from setup to sign-off with built-in to-dos, status reporting, and shared project views.
Every feature exists because it solved a real problem in a real depreciation study.
Run SL depreciation and amortization using industry-standard methods like equal life and average life group techniques — the same approaches U.S. utility regulators already rely on. Case comparison tools let you set two sets of assumptions side by side, so you can weigh the financial impact of different depreciation strategies before you commit to one.
Depreciation Workbench comes populated with algorithms built to fit Iowa curves, the industry standard. Graphical curve fitting lets you match standard curves to observed life data directly, for precise, defensible life estimates.
Predefined templates and automated alerts keep filings timely and standardized, cutting down the manual work of report generation so your team can focus on judgment calls instead of formatting.
Multiple layers of user rights mean colleagues, clients, and stakeholders can all work in the same project with access controls that match their role — no more emailing spreadsheet versions back and forth.
The DW Library publishes digital remodelings of publicly filed depreciation studies, ready to reference or build from. Don't see the one you need? We'll prepare a digital version from publicly available data.
