When should I use this installment cost comparator?
Use it before buying phones, appliances, furniture, courses, or any high-ticket item where full payment, installments, discounts, and rewards differ.
Is zero interest installment always cheaper?
Not always. A zero interest plan can still include fees, lose a cash discount, or earn fewer rewards. Non-zero plans should also convert APR into monthly cost.
How should I convert reward points?
If points can offset spending, enter their estimated cash value. For cashback or card rewards, use percent and set a cap if one applies.
Can I compare full-payment discounts with installment rewards?
Yes. Enter the full-payment discount or manual total, then add installment terms, APR, fees, and rewards. The table normalizes everything into true cost.
Will my calculation data be uploaded?
No. Inputs and calculations stay in your browser. No login is required and no purchase history is stored.
