How to use this calculator

The best result comes from comparing several scenarios, not relying on one number. Change one input at a time and watch how the result responds.

1. Start with realistic inputs

Use current balances, rates, payments, and time frames rather than ideal assumptions.

2. Compare at least three scenarios

Try conservative, expected, and aggressive versions of your plan.

3. Follow the next step

Use related Nobalio tools to connect this decision with your broader financial picture.
