🔢 Formulas & Calculation Logic
This **retirement savings longevity calculator** uses established financial principles to help you plan your future. Understanding these formulas is key to effective **retirement planning** and **financial forecasting**.
📌 Tab 1: Retirement Savings Goal Calculator
This calculator estimates the lump sum you need to save by retirement to cover your desired annual spending throughout your retirement years, accounting for inflation and investment returns.
Nominal Future Expense:
Your desired annual income will need to increase each year due to inflation to maintain the same purchasing power.
Expense$_t$ = Desired Income $\times$ (1 + Inflation Rate)$^t$
Where $t$ is the year in retirement.
Required Savings (Present Value of Withdrawals):
This is the total amount you need at the start of retirement. It's calculated by summing the present value of each year's inflation-adjusted withdrawal, discounted by your expected return rate.
Required Savings (PV) = $\sum_{t=1}^{\text{N}} \frac{\text{Expense}_t}{(1 + \text{Return Rate})^t}$
Where N is the retirement duration. This matches typical “savings projection” logic.
📌 Tab 2: Retirement Longevity Calculator
This calculator simulates your portfolio's balance year-by-year, showing how long your current savings will last given your annual withdrawals, expected investment return, and inflation.
Year-by-Year Simulation:
The simulation starts with your current savings. Each year, it subtracts the inflation-adjusted withdrawal amount and then applies the expected investment return to the remaining balance. This process continues until the balance hits zero or the planned withdrawal period ends.
Withdrawal$_t$ = Initial Annual Withdrawal $\times$ (1 + Inflation Rate)$^t$
Balance$_t$ = (Balance$_{t-1}$ - Withdrawal$_t$) $\times$ (1 + Return Rate)
The simulation stops when the balance reaches zero or the specified planned withdrawal period is met.
Sustainable Withdrawal Guideline:
A common guideline for sustainable withdrawals aims for an initial withdrawal of 4–5% of your portfolio's value in the first year of retirement, adjusted annually by inflation. This strategy is often cited by financial experts to help ensure your savings last throughout your retirement.

❓ FAQs: Retirement Savings & Longevity
Get quick answers to common questions about **retirement savings**, **longevity planning**, and **sustainable withdrawals**.
A: Our **retirement longevity calculator** estimates how many years your savings can support you. It considers your current balance, annual withdrawal rate (adjusted for inflation), and expected investment returns. Financial guidelines often suggest starting with a 4–5% initial withdrawal rate, adjusted annually for inflation, as a sustainable approach to make your savings last.
A: The **Retirement Savings Goal Calculator** tab estimates the lump sum needed to support your desired annual spending over a specified retirement period. This calculation factors in expected investment returns and the impact of inflation to give you a realistic target for your **retirement savings**.
A: Inflation erodes the purchasing power of money over time. Including an expected inflation rate (e.g., around 2.5%, as often assumed by financial experts like Fidelity in their planning models) ensures that your retirement income projections are realistic. It helps you understand how much more money you'll need in the future to maintain your current lifestyle, making your **retirement planning** more accurate.
A: Many financial authorities advise starting with an initial withdrawal of approximately 4% of your portfolio's value in the first year of retirement. This amount is then typically adjusted annually for inflation. This strategy aims to provide a high probability that your funds will last for a retirement period of 30 years or more, balancing income needs with portfolio longevity.
