Three typical deals, run through the same arithmetic as the calculators above. Indicative rates — the lender, the asset and the file move every number.
A $500,000 commercial loan over 10 years at 7.5% p.a., principal and interest, repays $5,935 a month. Over the full term that is $712,211 — $500,000 of principal and $212,211 of interest. Held to term, the interest bill is roughly 42% of the amount borrowed, which is why the term matters as much as the rate.
A $150,000 excavator on a five-year chattel mortgage at 8% p.a. with a 30% balloon ($45,000) costs $2,429 a month, with the balloon due at term end — $190,741 all up, $40,741 of it interest. The same deal with no balloon costs $3,041 a month but only $32,488 in interest: the balloon buys $612 a month of cashflow for about $8,250 in extra interest.
A commercial property purchase at $2,000,000 with a lender policy cap of 70% LVR supports a maximum loan of $1,400,000, leaving $600,000 of equity to fund plus stamp duty and transaction costs. At a 60% cap — common for specialised assets — the maximum loan drops to $1,200,000.
