Ledgerage
What it is
Ledgerage computes lease present value, right-of-use assets, lease liabilities, amortization schedules, journal entries and disclosures. Its calculations cover ASC 842, IFRS 16 and GASB 87. The web calculator works without an account and is described as free forever, rather than as a trial. The Free plan allows unlimited single-lease calculations, two saved leases and 25 API computations per month. Developers can send JSON requests to its REST API and receive computations, schedules, journal entries or classifications with citations to the applicable standard. Its MCP server provides four tools and names Claude Desktop and Claude Code as compatible clients. Pro costs $39 per month, billed month-to-month with no contract, and adds an unlimited portfolio, exports, modifications and remeasurements. Ledgerage says its engine is deterministic, cites standards behind results and reconciles amortization schedules to zero at term end. Results depend on user inputs and judgments and are informational, not accounting or legal advice.
