Elvira Books › Loan amortisation and interest tracking

Loans, with the interest split out for you

Every instalment you pay is part principal and part interest, in a proportion that changes each month. Recorded as one payment to one account, your interest expense is wrong and so is what you still owe.

The loan register: principal, rate, term, what is outstanding and what falls due next.

What Elvira works out

Contract or computed

The schedule can be computed by Elvira, or you can enter the instalment your loan agreement actually states and let the split follow from it. Banks round; agreements sometimes disagree with the mathematics by a few units, and the figure on the paper is the one you have to pay.

It checks itself

Elvira’s ledger check compares what the loan accounts hold against what the loans themselves explain, and names the entries responsible when they differ: so a journal posted straight to a loan account cannot sit there unnoticed.

Where this comes from

IFRS 9 Appendix A
The effective interest method allocates interest over the relevant period using the effective interest rate.
IAS 1.69
The portion of a loan due within twelve months is a current liability and is presented separately.
IAS 23.8
Borrowing costs directly attributable to a qualifying asset are capitalised; the rest are an expense of the period.
