009 — Debt Erosion Calculator

WHAT THIS IS

A calculator that determines the real interest rate on outstanding

debt after inflation — revealing whether fixed-rate borrowing is a

genuine cost, or a structural benefit quietly transferred from

lender to borrower.

RI = [(1+N)/(1+I)] − 1 → the rate that actually matters

WHAT IS INCLUDED

→ Interactive calculator — loan rate, inflation, instant real result

→ Real value of outstanding principal projected forward in time

────────────────────────────────

WHO THIS IS FOR

Anyone holding a fixed-rate loan who has only ever looked at the

does to it.
