About Ledgerage

Audit-grade lease accounting shouldn't take a spreadsheet and an afternoon.

Ledgerage exists so that anyone — an accountant, a small business, or an AI agent — can turn a lease into a present value, a right-of-use asset, a full amortization schedule, the journal entries and the disclosures in seconds, with every number traced back to the standard that produced it.

Mission

Make lease accounting instant — and agent-native

Since ASC 842 and IFRS 16 brought almost every lease onto the balance sheet, lease accounting has mostly been sold as enterprise software: long implementations, opaque pricing, and dashboards that assume a human is clicking through them. Everyone else falls back to a fragile spreadsheet rebuilt every quarter — which is exactly where the errors creep in.

Ledgerage is built the other way round: a free, no-account web calculator first, a clean API and MCP server as first-class citizens rather than an afterthought, and a single paid tier you only reach for once you need a saved portfolio, audit-ready exports and volume.

Who it's for

Accountants and agents, equally

Controllers and accountants use Ledgerage directly to compute a lease, tie out a schedule and export the journal entries and disclosures for the close. Developers embed the API into close and bookkeeping workflows. And AI accounting agents call the same engine through the MCP server — so instead of hallucinating a right-of-use asset, they get the same cited, reconciled numbers a human reviewer would.

How we build

Four properties on every result

Ledgerage does not have an opinion about your lease — it applies the standard and shows its work. Four properties make the output something you can put in a workpaper.

01

Deterministic

The engine is closed-form arithmetic, not a language model. The same lease always produces the same schedule to the cent — the property that makes a result reproducible and defensible in front of an auditor.

02

Cited

Every classification and measurement points back to the ASC 842, IFRS 16 or GASB 87 paragraph behind it. The citation travels with the API response and the exported workpaper, not just the marketing page.

03

Reconciled

Every amortization schedule closes the lease liability and the right-of-use asset to exactly zero at the end of the term. If it didn't tie out, it wouldn't be a workpaper.

04

One engine

The free web calculator, the saved portfolio, the exports and the API all call the same engine. The free result is as accurate as the paid one — the paid tier adds saving, exporting and volume, never accuracy.

Important disclaimer

Results are informational, not accounting or legal advice

Ledgerage provides automated lease-accounting calculations under ASC 842, IFRS 16 and GASB 87. The outputs — present values, right-of-use assets, lease liabilities, amortization schedules, journal entries, classifications and disclosures — are informational and depend entirely on the inputs and judgements you provide, including the discount rate, the lease term, and the classification assumptions.

Ledgerage is a computation tool, not a substitute for professional judgement or an audit. You are responsible for the inputs, for reviewing the results, and for your own accounting, reporting and compliance decisions — including whether to seek advice from a qualified accountant or auditor for anything with financial-reporting consequences.

Compute a lease — no account needed.
