How Can Your CPF Special Account Exceed the Full Retirement Sum (FRS)?

I often get this question from readers and friends:

"How can someone's CPF Special Account (SA) have more than the Full Retirement Sum? I thought there was a cap!"

It's a common misconception! Let me clarify how this works and why I've intentionally grown my own SA far beyond today's FRS.

How the FRS "Cap" Actually Works

The FRS limit only restricts two inflows into your Special Account:

Retirement Sum Top-Up (RSTU) Scheme: You cannot make voluntary cash top-ups or transfer your OA to your SA once it reaches the FRS.
MediSave Overflow: Funds from your MediSave Account (MA) stop flowing into your SA once SA hits FRS.

Crucially, these inflows continue UNRESTRICTED:

✅ Monthly salary contributions (employer + employee)
✅ Annual compound interest (currently 4% risk-free)

Why Exceeding FRS Is a Powerful Strategy

To grow your SA beyond the FRS and maximize that guaranteed 4% return, you need to:

Hit the FRS in your SA early (via top-ups, salary contributions, or investment returns).
Let compounding work over time through ongoing contributions and interest.

Since the FRS increases yearly (historically ~3% p.a.), your SA balance fueled by salary inflows and 4% interest can outpace it significantly. The earlier you hit FRS, the more you'll potentially withdraw at 55+.

Visualizing the Advantage: SA Growth vs FRS Inflation

Here's why starting early matters (illustrative example from VW CPF calculator):

Hypothetical growth: Starting FRS today at 35 @ 4% SA interest + $6k monthly salary contributions vs 3% FRS inflation = $200k more in SA than the FRS

My Personal Experience

This is exactly why my SA holds more than today's FRS. I reached my FRS years ago, and since then:

Monthly salary contributions + 4% compound interest
Substantial growth above the FRS ceiling

Yes, these funds are locked until age 55+ but for long-term wealth building, this risk-free return is unmatched in Singapore's investment landscape.
