FAQ

Is the interest truly zero for interest-free plans?

In card issuer interest-free promotions, no interest is charged to the consumer. However, the merchant may bear the fee, so one-time and installment prices could differ.

Can I calculate equal principal and interest loan payments?

This tool focuses on installment payments (simple division). For amortized loan payments, a dedicated loan calculator will be more accurate.

Can I enter a custom installment period?

In addition to the presets (3, 6, 9, 12, 18, 24 months), you can enter a custom period manually.
