Use planEASe calculators with Claude and other AI assistants

Ask for a loan payment, an interest rate conversion or a depreciation schedule in plain English. The assistant runs planEASe’s own calculation and gives you a link to check it.

What this is

planEASe offers its free financial calculators to AI assistants through the Model Context Protocol (MCP), an open standard that lets an assistant call outside tools. Instead of estimating the math itself, the assistant sends your numbers to planEASe, which has used these calculations for commercial real estate analysis since 1982.

Every answer includes a share link to the matching planEASe page with your exact inputs. Open it to check the result, change an assumption, or download a PDF report. No account, subscription or API key is needed.

Connect to Claude

Copy this address:

  1. In Claude, open Customize, then Connectors.
  2. Click + and choose Add custom connector.
  3. Name it planEASe, paste the address above, and click Add.
  4. Start a new chat and ask a question, such as one of the examples below.

On a Team or Enterprise plan, an organization Owner adds the connector once, and each member then clicks Connect. Custom connectors need a Claude account; free accounts are limited to one custom connector.

Connect to other assistants

Any AI assistant that supports remote MCP servers can use the same address: https://planease.com/mcp. Support depends on the product and your plan. For example, ChatGPT offers custom connectors on some paid plans. Check your assistant’s help pages for the current steps, since menu names change often. No sign-in is required.

What it can do

Loan Payment Planner (plan_loan_payment)

The level payment on a fixed-rate loan at weekly through annual payments, with total interest, the final payment and the effective annual rate. Optionally adds a yearly schedule (useful for balloon balances) or a table of payments at nearby rates and amounts. Loans from $100 to $900,000,000, up to 50 years.

Interest Rate Converter (convert_interest_rate)

Converts one rate into its equivalent at every compounding frequency, from annual to continuous. Use it to compare an APR with an APY, or quotes that compound differently.

Asset Depreciation Schedule (depreciate_asset)

Year-by-year U.S. federal MACRS schedules for residential and nonresidential buildings, qualified improvement property and cost segregation classes, with bonus depreciation and land excluded. The assistant will ask about details such as the land value and bonus percentage rather than guessing.

Try asking

  • “What is the monthly payment on a $2,000,000 loan at 6.75% amortized over 25 years?”
  • “A credit card quotes 24% APR compounded monthly. What is the effective annual rate?”
  • “Show the depreciation schedule for a $650,000 duplex with $150,000 of land, placed in service in March 2027.”
  • “Compare payments on a $400,000 loan from 6.5% to 7.5% over 30 years.”

Good to know

  • These are planning tools, not tax, legal or financial advice. A lender’s loan documents set actual payments.
  • The loan tool covers fixed-rate loans with level payments. It does not model interest-only periods, adjustable rates, fees or points.
  • The depreciation tool covers the common MACRS classes. It does not cover Section 179, vehicle limits, special-zone rules, the year of sale, state rules or AMT.
  • The numbers you enter reach our server only to produce the answer. We log the time, IP address and which tool was called, not the values. See the Privacy Policy.
  • Share links contain your inputs in the address, so anyone with the link can see them.
