How it is calculated

Maximum loan amount = payment × ((1 + monthly rate)^term − 1) ÷ (monthly rate × (1 + monthly rate)^term) — the annuity payment formula solved for the loan amount instead of the payment. At a zero rate it simplifies to amount = payment × term.

At the same payment, the loan amount grows with a longer term (more payments) and shrinks as the rate rises (more money goes to interest, less to principal) — the same two forces that drive loan overpayment.

The result is the amount available under a pure annuity schedule, without extra fees or a bank's down payment or collateral requirements. The actual approved limit may be lower than calculated here.
