Who it is for
Buyers and remortgagers running quick payment scenarios.
Mortgage payment and total interest calculations
Overview
A mortgage calculator that answers payment questions asked in a sentence. A loan amount, a rate, a deposit percentage, and a term are enough for a monthly figure.
Total interest across the life of a loan is the other question the record shows, using a thirty year term as its example. The listed prompt asks what the payment would be on 300K at 6.75 percent over thirty years. Figures come from the inputs given in the message, so a changed rate or deposit means a fresh question. Spheric Admin Limited publishes it.

The monthly payment and the lifetime interest question are both handled from the same phrasing.
Availability
AnyMortgageCalculator is listed in the ChatGPT apps directory only. Spheric Admin Limited has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from AnyMortgageCalculator's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Spheric Admin Limited, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
