Reviewed by Calculator Editorial Team

Determining what percentage of your 401k to keep in a bank account requires careful consideration of your financial goals, risk tolerance, and investment strategy. This guide explains how to calculate the optimal percentage to keep in a bank while maximizing growth potential.

Introduction

A 401k is a retirement savings plan offered by employers, and it's important to diversify your investments beyond just the plan. Keeping a portion of your 401k in a bank account provides liquidity and safety, while the rest can be invested for long-term growth.

The percentage you should keep in a bank depends on factors like your age, retirement timeline, and risk tolerance. Generally, younger individuals can afford to take more risk with their investments, while those nearing retirement should prioritize safety.

How to Calculate

To determine what percentage of your 401k to keep in a bank, follow these steps:

  1. Assess your financial goals and timeline for retirement.
  2. Determine your risk tolerance based on your age and investment horizon.
  3. Calculate the percentage of your 401k that should remain in a bank account for liquidity and safety.
  4. Use the calculator below to get a personalized recommendation.

Formula

The percentage of your 401k to keep in a bank can be calculated using the following formula:

Bank Percentage = (Total 401k Balance × Safety Factor) / Total 401k Balance

The safety factor is determined by your age and risk tolerance.

Factors to Consider

Several factors influence the percentage of your 401k you should keep in a bank:

  • Age: Younger individuals can afford to take more risk with their investments.
  • Retirement Timeline: Those closer to retirement should prioritize safety.
  • Risk Tolerance: Higher risk tolerance allows for more aggressive investment strategies.
  • Liquidity Needs: Immediate financial needs may require a higher percentage in a bank.

Consult with a financial advisor to tailor your investment strategy to your specific needs and goals.

Example Calculation

Let's say you have a $100,000 401k balance and you're 35 years old with a moderate risk tolerance. Based on standard financial planning guidelines, you might decide to keep 20% of your 401k in a bank account for safety and liquidity.

Using the formula:

Bank Percentage = ($100,000 × 0.20) / $100,000 = 20%

This means you should keep $20,000 in a bank account and invest the remaining $80,000 in other investment vehicles.
