Accounting standard: FRS 102  ·  Interest method: Effective Interest (IRR)  ·  All figures ex-VAT unless stated
Agreement Details
All months same amount. Use Payment Groups for agreements with irregular payments, balloons, or different first/last payments.
FRS 102 mode: The calculator derives the implicit interest rate (IRR) using Newton-Raphson and builds the full amortisation schedule using the effective interest method (FRS 102 s20). Doc fee is treated as a finance cost capitalised into the principal and spread over the term via EIR. VAT and advance rental reduce the amount financed; part exchange reduces it as a deposit equivalent. A prepayment in a later month reduces the outstanding balance — the IRR is fixed at inception, but future interest charges fall as the balance drops, shortening the agreement.
Early Settlement
Enter the month number and the settlement figure from the lender's settlement letter. The calculator will derive the carrying value at that date, post the settlement journal, and flag the difference as a finance charge adjustment. Asset disposal is handled separately in Xero Fixed Asset Register.
