The scenario
The balance receives BRL 20,000 in month 60 in both variants. One removes final payments; the other keeps 360 months and recalculates the payment.
How to interpret
Term reduction prioritizes removing interest-bearing periods. Payment reduction prioritizes monthly cash-flow relief. The indicators quantify this trade-off only for the scenario.
