The Quadreto from Caisse d’Épargne combines a PEL with term accounts (CAT) in a unique arrangement. The classic PEL, on the other hand, operates independently with periodic deposits. Comparing these two options requires measuring their real net yield, taxation, and flexibility, three parameters that have significantly evolved since January 2026.
Net yield of Quadreto and PEL 2026 compared to regulated savings accounts
The gross rate of the PEL opened in 2026 is set at 2% gross guaranteed for the entire duration of the plan. This rate applies to both the PEL included in the Quadreto and the PEL subscribed alone. The difference comes from the term accounts linked to the Quadreto, whose remuneration depends on the chosen duration (from 4 to 10 years).
Since January 1, 2026, the flat tax has been raised to 31.4% (12.8% tax + 18.6% social contributions). It applies to the interests of both the PEL and the CAT. Therefore, a PEL at 2% gross now yields only about 1.37% net after the single flat-rate withholding.
To place these figures in relation to available alternatives, a comparator for Quadreto Caisse d’Épargne 2026 rates allows visualization of the gap with tax-free savings accounts.
| Investment | Gross Rate | Taxation | Approx. Net Yield | Liquidity |
|---|---|---|---|---|
| PEL 2026 (classic or Quadreto) | 2% | Flat tax 31.4% | ~1.37% | Blocked for at least 4 years |
| Livret A (since August 2026) | 1.70% | Exempt | 1.70% net | Available at any time |
| LEP (since August 2026) | 2.50% | Exempt | 2.50% net | Available at any time |
The hierarchy is clear: the LEP yields almost twice as much net as the PEL 2026, without any fund blockage. The Livret A also surpasses the PEL in net yield while remaining completely liquid.
Flat tax at 31.4%: what the Quadreto loses compared to the PEL alone
The Quadreto combines a PEL and several term accounts funded by a single deposit (minimum 6,000 euros). The interests of the CAT are subject to the same flat tax of 31.4%. The question is whether the gross yield of the CAT compensates for this withholding.
In a classic PEL, deposits are gradual (minimum of 45 euros per month). The saver retains control over their monthly cash flow. With the Quadreto, the capital is immobilized from the outset. This initial blockage is a significant constraint for a net yield that remains comparable.
The remuneration gap between the CAT of the Quadreto and the bare PEL depends on the chosen duration. For shorter terms (4 years), the gross difference is small. For longer durations (8 to 10 years), the CAT may offer a slight surplus, but the flat tax at 31.4% absorbs nearly a third of it.
- Over 4 years, the net gain of the Quadreto compared to the PEL alone is marginal, as the short CATs offer rates close to the PEL itself.
- An early withdrawal from the Quadreto results in the closure of the PEL and the loss of benefits related to the housing savings loan.
- The ceiling of the PEL remains fixed at 61,200 euros, whether the plan is integrated into the Quadreto or subscribed alone.
Housing savings loan: the only argument that can justify a PEL in 2026
The PEL entitles the holder to a housing savings loan whose rate is set at the opening of the plan. For PELs opened in 2026, this loan rate is known at the time of subscription and guaranteed for the entire duration of the plan (up to 10 years). The maximum borrowable amount can reach 92,000 euros.
If mortgage rates rise significantly in the coming years, having a right to a loan at a guaranteed rate becomes a real advantage. Conversely, if credit rates remain stable or decrease, this loan right has no added value compared to a conventional loan.
The Quadreto does not change the conditions of the housing savings loan: the loan right is identical to that of a classic PEL. The only difference concerns the accumulation of capital, which occurs through a single deposit instead of monthly deposits.
When the classic PEL is sufficient
For a saver who wishes to build up a contribution gradually, the classic PEL with its minimum monthly deposits of 45 euros remains more flexible. It does not require mobilizing 6,000 euros at once.
When the Quadreto is of interest
The Quadreto may suit a saver with dormant capital they wish to allocate to a real estate project with a horizon of 4 to 10 years. The single deposit automates the obligations of the PEL and avoids the risk of forgetting a deposit (which would lead to the closure of the plan).
Arbitration PEL, Quadreto or savings account: the decision criteria
The choice depends on three concrete variables:
- The certainty of the real estate project: without a purchase project in the next 4 to 10 years, neither the PEL nor the Quadreto is justified compared to the Livret A or the LEP.
- The capital available immediately: below 6,000 euros, the Quadreto is inaccessible. The classic PEL remains the default option.
- Eligibility for the LEP: a saver eligible for the LEP (subject to income conditions) obtains 2.50% net without blockage or taxation, making the PEL 2026 less competitive in pure yield.
The PEL 2026, whether integrated into the Quadreto or subscribed alone, is only justified by the guaranteed loan right. Based solely on the criterion of net yield, regulated savings accounts have surpassed it since the flat tax was raised to 31.4%. A saver without a specific real estate project has every interest in first maximizing their Livret A and LEP ceilings before considering a PEL.
