Are You On Track? Retirement Gap Checker
Compare the nest egg you need for your desired retirement income against what your current plan projects. The gap is simply needed − projected — and we show the extra monthly savings required to close it.
Your Details
A 4%–8% planning range is typical. Returns are assumptions, not guarantees.
4% is the classic safe-withdrawal rule.

How the gap is calculated
Target nest egg = desired annual income ÷ withdrawal rate. Projected savings compounds your current balance and monthly contributions at the assumed return. Gap = target − projected (zero if you are already ahead). The extra monthly savings solves the future-value annuity formula for the amount that closes the gap by your retirement age. All figures are estimates — test a conservative return too.

Frequently asked questions
What does "on track" mean here?
You are on track if your projected savings at retirement meet or exceed the nest egg your desired income implies (desired income ÷ withdrawal rate). The calculator shows the exact gap and the extra monthly savings needed if you are behind.
What withdrawal rate should I use?
The classic 4% rule assumes a ~30-year retirement with inflation-adjusted withdrawals. More conservative planners use 3–3.5%. It is a planning heuristic, not a guarantee — adjust for your health, longevity, and bequest goals.
Why is my gap different from other retirement calculators?
Gaps depend entirely on the return assumption, withdrawal rate, and current savings you enter. Small changes in assumed return compound over decades, so always test a conservative scenario alongside an optimistic one.

No. CompoundFig provides educational estimates only. Outcomes depend on market returns, fees, taxes, and inflation — none of which are guaranteed. Consult a licensed financial advisor before making decisions.
