How it works

The Retirement Gap Calculator helps you identify the difference between your projected retirement income and your expected expenses. To estimate your needed retirement income, we start with your current income and apply a replacement rate, which represents the percentage of your income you aim to maintain in retirement. For example, if your current income is $80,000 and you choose a replacement rate of 80%, your needed retirement income would be $64,000 annually. Next, we factor in your sources of retirement income, including Social Security, pensions, and portfolio income. In this case, if you expect to receive $24,000 from Social Security and $30,000 from your portfolio, your total projected income would be $54,000. The annual retirement gap is calculated by subtracting your projected income from your needed retirement income. Here, it would be $64,000 (needed) - $54,000 (projected) = $10,000. This gap indicates how much more you need to save or adjust your plans to ensure a financially secure retirement.

Tips

  • Review your expenses regularly to ensure your retirement income projections remain accurate.
  • Consider increasing your savings rate if your projected income falls short of your retirement needs.
  • Explore additional income sources, such as part-time work or investment options, to bridge any gaps.
  • Stay informed about changes in Social Security benefits and retirement account rules that could impact your planning.
