Overview

Ledgerage calculates lease present value, right-of-use assets, liabilities, amortization schedules, journal entries and disclosures under ASC 842, IFRS 16 and GASB 87. A no-account web calculator supports individual calculations, while saved portfolios and API use make the product more relevant to teams with recurring lease work or software to integrate.

The engine is described as deterministic, cites the applicable standard behind its results and reconciles each amortization schedule to zero at the end of the lease term. Those properties make outputs easier to trace and check; they do not settle accounting judgments or validate the inputs. Ledgerage says its results are informational, not accounting or legal advice.

Key features

Calculations and reporting

Journal entries and disclosures extend the product beyond present-value calculations. Pro adds lease modifications and remeasurements, which is useful when a portfolio needs updates as well as initial schedules. Teams seeking a broader lease-management workflow should weigh those capabilities against the 1,000-saved-lease ceiling on Pro.

API and MCP access

The REST API accepts JSON and returns calculations, schedules, journal entries or classifications with citations to the relevant standard. That makes it a practical fit for developers embedding lease calculations in another system, subject to monthly computation quotas and request-rate limits. The MCP server exposes four tools and names Claude Desktop and Claude Code as compatible clients, bringing the same general workflow to those AI clients.

Security and support

API keys can be sent as Bearer tokens or through the x-api-key header; Ledgerage says it stores only a hash of each key. API questions can be directed to hello@ledgerage.com. These details help with integration planning, though they do not change the need to review outputs and access controls within a team’s own stack.

Pricing

Ledgerage has a free plan and a month-to-month Pro plan; there is no free trial. The web calculator is described as free forever, so an occasional single-lease calculation does not require a subscription or account. The paid tier is a clearer fit for ongoing portfolio work, exports or heavier API use.

Plan	Price	What it includes	Limits and fit
Free	0.00 USD per free	Unlimited single-lease calculations, two saved leases, 25 API computations per month, 10 API requests per minute and MCP.	Suitable for occasional calculations or a small integration trial; the two saved leases and low API quota constrain sustained portfolio and automated use.
Pro	39.00 USD per month, billed month-to-month; no contract	Unlimited lease portfolio, 1,000 saved leases, 5,000 API computations per month, 120 API requests per minute, Excel/CSV/PDF exports, modifications and remeasurements, and hosted MCP server.	For teams with regular lease work, reporting exports or higher API demand. The saved-lease cap and monthly computation quota still matter at scale.

Platforms

Ledgerage is available on the web and through an API. MCP access supports Claude Desktop and Claude Code; the Free plan includes MCP, while Pro specifies a hosted MCP server.

Who it's for

Accountants and controllers can use Ledgerage for standards-based calculations and reporting outputs, while small businesses can use the no-account calculator for individual leases. Developers have a JSON REST API to embed calculations, and teams using the named Claude clients can access the MCP tools. It is a weaker fit for organizations that need outputs treated as authoritative accounting advice or whose portfolio exceeds Pro’s saved-lease limit.

Pros and cons

Traceable calculations: Standard citations and schedule reconciliation help reviewers follow and check the generated outputs.
Useful integration paths: JSON API and MCP access serve software workflows as well as direct web calculations.
Low-friction entry: The calculator works without an account, and Free includes MCP access.
Meaningful Pro limits: Five thousand monthly API computations and 120 requests per minute suit more regular use than Free, but teams should check these quotas against their workload.
Judgment remains with the user: Informational outputs based on user inputs are not a substitute for accounting or legal advice.
Portfolio ceiling: Pro saves up to 1,000 leases, which may not suit larger portfolios.

Alternatives

For a wider comparison of lease tools, start with Lease Accounting Software. Consider Nakisa Capital Projects Suite if you want an API and web platform and are prepared to request a tailored demo. MRI Property Management X is another paid API and web option, with Windows support as well, and requires a demo for pricing.

Planon may suit teams that value a free trial and Android or iOS access alongside web and API platforms. Acumatica Accounts Payable is worth considering when deployment preferences and expected usage should shape custom pricing, with unlimited users. For public-sector needs, compare Infor Public Sector, a paid platform spanning web, API, mobile, self-hosted and Windows options.

IRIS Star Practice Management is a modular option for accounting firms. Visual Lease offers personalized pricing and a pricing consultation, while LeaseAccelerator offers pricing by request and a demo.

Verdict

Choose Ledgerage if you need lease calculations under ASC 842, IFRS 16 or GASB 87 that can be checked and integrated through an API or MCP. The no-account calculator is a useful starting point, and Pro’s exports and higher limits support recurring work at a month-to-month price. Look elsewhere if you need accounting advice, a larger saved portfolio than Pro allows, or a broader platform better matched to your existing operation.
