Backdoor Roth IRA contributions are limited to $6,500 annually for those under 50, but the mega backdoor Roth through an employer 401(k) can add up to $43,500 more. Not all plans allow this, so check your summary plan description. For more on this topic, see Geographic Arbitrage.

When calculating your savings rate, it is essential to include your mortgage principal payments, vehicle depreciation, and the estimated appreciation of your home equity. Most calculators fail to account for these crucial variables. For more on this topic, see Rental Property Cash Flow.

Frugal living does not mean deprivation. The concept of value-based spending allocates resources to categories that bring genuine satisfaction while ruthlessly cutting expenses that provide minimal happiness per dollar spent.
