You will definitely have your OASI pension. The amount of this pension will depend on how many years of contributions you have accumulated. Your OASI office can tell you the potential amount of your future OASI pension.
If you are employed and are a member of a pension fund, you will also receive a pension from the latter. The insurance certificate issued by your pension fund shows the likely amount of your future pension.
If you pay into the OASI scheme without interruption and are also insured with a pension fund via your employer, you can expect to receive pension income equal to about 60% of your final income as an employee. But that figure can be appreciably lower if you earned a high salary, took longer breaks from work or did not pay all your contributions. That is why the provision you make yourself via the third pillar is key to making up any shortfall in income.
