Principal payment
Payment that reduces debt and builds equity rather than being economically consumed.
Simple definition
Payment that reduces debt and builds equity rather than being economically consumed.
Why it matters
This term changes how inputs, cash flows or results should be interpreted. RATIOXA keeps it explicit so two options are compared on the same basis.
Worked example
Of a €1,700 payment, €900 may be interest cost and €800 wealth building.
