What this calculation is for
A retirement-savings projection translates today’s balance and recurring contributions into a possible future fund. It is most useful as a range of scenarios rather than a single promise. Try lower returns, a later contribution start and higher inflation before deciding whether a plan is resilient.
How the method works
The model compounds the entered balance, adds scheduled contributions and compares nominal dollars with an inflation-adjusted balance. An illustrative withdrawal percentage converts the projected balance into annual income. Neither the return nor the withdrawal percentage is guaranteed.
A worked example
A projected $1,000,000 portfolio supports a $40,000 first-year draw at a 4% assumption before tax. If retirement is many years away, $40,000 then has less purchasing power than $40,000 today.
Assumptions and real-world differences
Constant returns hide market volatility and sequence risk. Contribution limits, tax treatment, benefit eligibility and future Social Security payments are not automatically determined. Employer contributions are included only where the tool provides a matching field.
Frequently asked questions
- Is the 4% illustration a safe-income guarantee?
- No. Outcomes depend on time horizon, markets, fees, taxes and spending flexibility.
- Why show today’s dollars?
- It separates projected nominal growth from the purchasing power lost to inflation.
