For informational use only. Holding costs are estimates, not a lender payoff quote or financial advice. Your agreement’s interest basis, changing balance, curtailments, and fees may differ. Confirm the terms with your lender before relying on the result.
How to use this tool
- 1Enter the financed balance and your lender’s APR.
- 2Add origination fees, monthly fees, and daily carrying assumptions.
- 3Compare holding periods and download your cost table.
How the result is built
Simple daily interest uses financed balance × APR ÷ your chosen 360- or 365-day basis. Monthly fees are prorated over 30 days. The financed balance is assumed constant; enter a lower balance to model curtailments.
An example from the lot
A $15,000 balance at 12% APR on a 365-day basis accrues about $4.93 a day before fees and other holding costs.
