Am I saving enough to retire? This calculator grows your current savings and monthly contributions to your retirement age, then applies the 4% safe-withdrawal rule to show the yearly income your nest egg can sustain. It compares that against the income you want — kept in today's dollars — and tells you exactly how much more to save each month to close any gap.

Your savings grow at your expected return ABOVE inflation each year until retirement — so every figure stays in today's dollars (real purchasing power).
Each monthly contribution is grown the same way and summed — this future-value of a series is your contributions' share of the nest egg.
The 4% rule turns the nest egg into income: a safe yearly withdrawal ≈ nest egg × your withdrawal rate (4% by default).
The nest egg you need is simply your desired income ÷ the withdrawal rate (25× your spending at 4%). The difference vs your projection is your surplus or shortfall, and we solve for the extra monthly saving that erases a shortfall.
A common rule of thumb is 25× your desired annual spending (the inverse of the 4% rule). This calculator does it for you: it inflates the income you want to your retirement year and divides by your withdrawal rate to show the target nest egg.
What is the 4% rule?
The 4% rule says you can withdraw about 4% of your portfolio in the first year of retirement, then adjust for inflation each year, with a high chance the money lasts ~30 years. Lower the withdrawal rate for a longer or more conservative retirement.
Does this include Social Security or CPP/OAS?
No. The projection is from your own savings only — government benefits like US Social Security or Canada's CPP and OAS are NOT included. Any benefits you expect reduce how much you personally need to save, so treat the shortfall as a conservative, savings-only figure.
Are the results in today's dollars?
Yes. We grow your savings at your return ABOVE inflation, so your nest egg, safe income, and goal are all in today's purchasing power — $50,000 of income means $50,000 of today's spending power. A higher inflation assumption means lower real growth and a smaller projected nest egg.
