01
Treat a ZUS forecast as an estimate
ZUS explains that its pension calculator produces a projection rather than a guaranteed future benefit. Use your latest account information and the relevant retirement assumptions. This tool does not reproduce account valorisation, initial capital or life-expectancy conversion rules.
02
Classify supplementary savings by payment form
For a supplementary account, first decide whether you are modelling accessible capital or recurring payments. An account balance is not itself a monthly pension. Check restrictions, taxes and withdrawal schedules with the relevant institution before combining it with liquid savings.
