Estimate a plan with the interest calculator

Use the public calculator to compare an amount and plan before shopping, then confirm the live checkout figures.

1 min read ยท Reviewed September 21, 2026

Create an estimate

  1. Open Calculate CanPay Interest on canpaybnpl.com.
  2. Enter the proposed purchase amount and choose a weekly, bi-weekly or monthly plan.
  3. Review the indicated charge, estimated total, first payment and later schedule.
  4. Compare plans before starting checkout.

An estimate is not an approval

The calculator does not reserve credit, approve an application, check merchant eligibility or create an order. Your live checkout recalculates the selected cart using current settings and account rules.

If figures differ

Use the live checkout breakdown for the purchase and do not confirm until you understand it. Take note of the amount and selected plan and ask support for clarification without sharing payment credentials.
