Investing in bonds is traditionally viewed as less risky and more predictable than investing in stocks. Bonds are commonly used to diversify an investor's portfolio. Below is a list of brokerage firms that offer not only the lowest commissions on buying bonds but also great and easy-to-use bond research and trading tools.

Best Bond Brokerage Firm: Ally Invest


Ally Invest rating


Ally Invest is a solid brokerage firm with a long history of some of the lowest commissions on stocks, options and mutual funds. The company also offers great pricing on bonds trading:

  • Municipal/Corporate Bonds: $1.00 per bond with a $10 minimum and $250 maximum per transaction
  • Treasuries: $0 commission (markdown or markup is used)
  • Certificates of Deposit (CDs): $24.95 per transaction

Ally Invest may act as a principal on some fixed-income transactions. In this case, a markdown or a markup will be added or subtracted from every purchase or sale. This markup or markdown will be included in the price quoted to an investor who will not be charged any commission or transaction fee for a principal trade.

Ally Invest provides great tools for finding and researching bonds such as the Bond Finder and the Bond Calculator. The easy-to-use Bond Calculator will help investors determine the value of a bond based on its description, which includes its CUSIP number, coupon, maturity, type and other features.


Ally Invest T-Bills


The Bond Finder helps investors choose types of bonds (treasuries, municipals, corporates, agencies, CDs or Strips) and filter them by the safety level (credit rating of a bond) and taxability (taxable, non-taxable or both). Additional features such as the desired investment amount and the time horizon can be specified to narrow the results.

Another great tool at the brokerage firm is the Bond Ladder Builder. By selecting types and specifying bond details, investors can build 2 to 21 rungs of ladders that suit their investment objectives and time horizon.
