AAR32 - Listener Q&A: How to Calculate Your Real Savings Rate

What It Covers

Evan Ray explains how to accurately calculate savings rates by converting pretax 401k contributions to after-tax equivalents, and provides a framework for building emergency funds scaled to individual circumstances including home and vehicle maintenance costs.

Key Questions Answered

• •401k Savings Calculation: Convert pretax 401k contributions to after-tax values by finding your effective tax rate from last year's federal return, then reducing 401k amounts by that percentage to compare accurately against other post-tax spending and savings categories.
• •Emergency Fund Target: Maintain six months of expenses in a high-yield savings account as a baseline, then add one to three percent of home value annually for maintenance reserves, scaling up based on age and condition of property and vehicles.
• •Tax Rate Approximation: Google your effective tax rate using your taxable income and state, or manually calculate bracket-by-bracket through current IRS tables. This percentage applies only to pretax accounts like traditional 401ks and HSAs, not Roth accounts or taxable savings.
• •Emergency Expense Strategy: Use high-yield savings first for unplanned costs, credit cards only as short-term bridges under one month, then consider HELOCs or home improvement loans for larger expenses. Avoid withdrawing from Roth IRAs which interrupts compounding growth permanently.
