The public purchase-option formula
Apple explains the calculation as the list price at lease signing, less lease payments already made, any down payment, and remaining discounts or trade-in credits. Applicable tax and an assessed damage fee can be added separately.
New Apple Upgrade leases normally do not allow a voluntary down payment, so that input is generally zero. It remains part of the general formula because your individual agreement controls.
- Pre-tax purchase option = signing list price − credited lease payments − down payment − unused credits
- Amount due = pre-tax purchase option + applicable purchase tax + assessed damage fee
- Total cost to own = all outlay already paid + amount due
Why the monthly payment is not enough
A low monthly lease payment can be paired with a larger purchase option. Without that purchase amount, a lease-to-own comparison is incomplete. Do not assume the purchase option is a standard residual percentage; Apple has not published one universal rate.
Inputs you should copy from your agreement
If Klarna provides a final purchase quote, that quote controls. Use the calculator as an audit trail: each number remains visible so you can understand the total.
- Original list price for the exact storage and configuration
- Lease payments Klarna credits toward the purchase option
- Unused trade-in or promotional credit
- Purchase-option tax shown for your location
- Any condition or service fee after assessment
