Bar length is proportional to year-end balance. Each year: beginning balance grows by 7% (interest), then your $10,000 contribution is added.

Showing first 5 of 30 years. The chart above shows the full accumulation phase.

Future Value

Standard FV formula combining a present sum and recurring annual contributions: FV = PV(1+r)^t + PMT × [((1+r)^t − 1) / r].

Monthly Withdrawal

See the sustainable monthly income your nest egg can support throughout retirement, divided evenly across all withdrawal months.

Inflation-Adjusted

Set an inflation rate (default 3%) and instantly see today's purchasing-power equivalent of your future monthly income.

Growth Chart

Year-by-year accumulation table shows starting balance, interest earned, contribution, and ending balance from now until retirement.

How is the total at retirement calculated?

Using the future-value formula for a present sum plus an ordinary annuity: FV = PV × (1 + r)^t + PMT × [((1 + r)^t − 1) / r], where PV is current savings, PMT is annual contribution, r is the annual return as a decimal (e.g. 0.07 for 7%), and t is years until retirement (retirementAge − currentAge).

What is the inflation-adjusted monthly income?

It is the nominal monthly withdrawal discounted back to today's dollars using the inflation rate you set: monthlyReal = monthlyNominal / (1 + inflation)^t. This tells you what your future income is actually worth in current purchasing power.

Should I use nominal or real (inflation-adjusted) return?

Either works. If you enter a nominal expected return (e.g. 7%) and a 3% inflation rate, the inflation-adjusted income will reflect today's purchasing power. If you enter a real return (e.g. 4%) and set inflation to 0%, the nominal and inflation-adjusted figures will match.

How does the growth chart work?

Each year the calculator applies your expected return to the starting balance (investment growth) then adds your annual contribution. The chart shows how compounding accelerates in later years as the balance grows.
