CPAG vs SCHZ

CPAGBF/m Compoundr U.S. Aggregate Bond ETF

SCHZASchwab U.S. Aggregate Bond ETF

In short

CPAG A core U.S. bond fund built to compound rather than pay out. It tracks the Nasdaq Compoundr U.S. Aggregate Bond Index, and income stays inside the fund instead of landing in your account as cash.

SCHZ Schwab's core bond holding: the broad U.S. investment-grade bond market, over 10,000 issues deep, for 0.03% a year. That is the floor of a category whose median fee is more than ten times higher. Running since 2011, pays monthly.

Stated mandate

CPAG The fund seeks investment results corresponding to the Nasdaq Compoundr U.S. Aggregate Bond Index. It generally uses replication and may use representative sampling when full replication is not practicable.

SCHZ The fund seeks to track the total return of an index representing the broad U.S. investment-grade bond market.

Why people hold it

• CPAG Income compounds inside the fund instead of arriving as cash, so there is nothing to reinvest by hand.
• At 0.31% a year, it undercuts the typical fund in the core bond crowd.
• Simple machinery: replicate the index, and sample only when full replication is not practical. No side bets bolted onto the mandate.

• SCHZ 0.03% a year sits at the category floor, against a cohort median of 0.36%. Only a short list of aggregate-bond funds matches it, including AGG, BND and SPAB.
• Tracks the Bloomberg US Aggregate Bond Index tightly, one of the cleanest index implementations among the 187 funds in its peer group.schwabassetmanagement.com
• One ticker, thousands of investment-grade U.S. bonds, income paid monthly. The plumbing of a bond portfolio without buying a single bond yourself.
• Live since 2011 and now a multi-billion-dollar fund that trades actively, so trading costs on ordinary retail-sized orders tend to be minor.

Worth knowing

• CPAG The 0.03% giants (BND, SPAB, SCHZ) are right there. The compounding wrapper is what the extra fee buys.
• Launched in 2025, still small and thinly traded, so the record is short and spreads can run wider than the mega-Aggs. Limit orders earn their keep.
• Nothing shows up in your account to spend. That is a different rhythm from a core bond fund that pays monthly.

• SCHZ This is duration exposure, not a cash substitute. Interest-rate moves, not credit selection, drive most of the ride, and that is the weakest part of its risk profile.
• Investment grade and U.S. only: no high-yield, no foreign bonds. Funds like BNDX cover the international side of the cohort.
• The aggregate-bond aisle is commoditized. Against AGG, BND and SPAB at the same 0.03%, the differences come down to index variant and where you already custody, not fee.
