Rules of Thumb – Chris Boyd and Jeff Perry dig into a variety of financial generalized rules of thumb when it comes to personal finance ratios. Chris starts off by questioning Jeff on his views about how much is too much regarding common family purchases such as home costs and automobile buying. Chris and Jeff debate the best way to approach student debt and student loans (they don't exactly agree). Jeff asks questions to Chris about common rules when it comes to how much one should be saving for retirement. Jeff next asks Chris for his view of how risk exposure to stocks changes as an investor grows older.
