Getting Started 🧮🌴 Retirement Savings Calculator

Introducing the PortfolioGPT Retirement Savings Calculator

The Retirement Savings Calculator helps you quickly see whether you’re on track for retirement and how much you may need to save each month to hit your future income or nest-egg goal. It projects your savings forward using your current balance, ongoing contributions, years until retirement, and an assumed long-term investment return so you can turn vague “someday” plans into a clear retirement savings roadmap.

Similar to leading online retirement tools, the calculator compares your projected retirement balance with an estimated amount needed to support your desired lifestyle, then highlights any gap and suggests a savings level to help close it. This gives Gen Z and Millennial investors an intuitive way to experiment with different savings rates, retirement ages, and goals—without spreadsheets or complex math.

What the Calculator Takes into Account

To keep the experience simple but powerful, the calculator focuses on a small set of high-impact inputs: your current age, target retirement age, total current retirement savings, and how much you're saving monthly or annually. It then uses compound growth to estimate your future balance and benchmarks that against a retirement spending target or income replacement percentage (for example, 70–80% of your current income).

Behind the scenes, the engine applies reasonable default assumptions for long-term investment returns, inflation, and retirement length that you can optionally refine via “advanced settings.” This keeps the main UI approachable while still allowing more advanced users to tune the modeling to their preferences when needed.

Key Outputs You'll See

Once you run a calculation, the tool surfaces a projected retirement balance at your chosen retirement age alongside an estimated amount required to support your desired level of spending. You'll see at a glance whether you appear to be on track, ahead, or behind based on those assumptions.

The calculator then suggests a monthly or annual savings target that would move you closer to your goal. Many users interact with this like a sandbox: adjusting retirement age, savings rate, or spending target and immediately seeing how those changes impact the projection. In PortfolioGPT, this savings target becomes a natural input into your downstream portfolio construction flows.

Step 1: 🎯 Set Your Retirement Timeline

Start by entering your current age and the age you'd like to retire. This defines your investing time horizon—the number of years your contributions can compound before you start drawing down your portfolio. A longer horizon generally means each dollar has more time to grow, reducing how much you may need to save each month.

Step 2: 💰 Enter Current Savings

Next, enter the total of all accounts you've earmarked for retirement—such as 401(k)s, IRAs, and brokerage accounts dedicated to long-term retirement investing. This sets your starting point so the calculator can project growth from your existing nest egg plus future contributions.

Step 3: 📈 Add Your Ongoing Contributions

Tell the calculator how much you're contributing toward retirement each month or year. You can include your own savings plus any employer match from workplace plans for a more realistic projection. The tool compounds these contributions over your full time horizon to estimate your balance at retirement.

Step 4: 🏡 Define Your Retirement Lifestyle

Specify your target retirement lifestyle by either entering a desired annual spending level in today's dollars or selecting an income replacement percentage (for example, targeting 75% of your current pre-tax income). This becomes the benchmark the calculator uses to decide how large your nest egg should be at retirement.

Step 5: ⚙️ Review Advanced Assumptions (Optional)

For users who want more control, expand the advanced settings to adjust the default assumptions for long-term investment returns, inflation, and years in retirement. Tweaking these levers lets you stress-test more conservative or more optimistic scenarios while keeping the core interaction simple.

Step 6: 🚀 Run the Calculation and Explore

Click the "Calculate" button to generate your projection. The calculator will display your estimated balance at retirement, how that compares to your required amount, and a suggested savings level to help close any gap. Use sliders or inputs to increase contributions, change retirement age, or adjust your goal and instantly see how your trajectory changes.

From here, PortfolioGPT can take your target savings level and plug it directly into AI-generated portfolio ideas tailored to your risk tolerance, time horizon, and preferred asset classes—turning a simple retirement projection into an actionable investing plan.
