| Scenario | Current Age | Retirement Age | Current Savings | Monthly Contribution | Desired Monthly Income Today | Other Income at Retirement | Illustrative Outcome |
|---|---|---|---|---|---|---|---|
| Balanced long-term plan | 35 | 65 | $150,000 | $1,200 | $5,000 | $2,200 | May support a multi-decade retirement with disciplined saving and moderate return assumptions. |
| Late saver catch-up | 48 | 67 | $80,000 | $2,000 | $6,000 | $2,500 | Needs stronger contributions or lower spending targets to improve funding coverage. |
Accumulation phase: Monthly savings growth follows Bm = Bm−1 × (1 + r/12) + Cm.
Contribution growth: Each new year increases the monthly contribution by the annual contribution growth rate.
Inflation adjustment: Retirement income need is estimated with Future Income = Today’s Income × (1 + inflation)^years.
Tax adjustment: Gross portfolio withdrawal = Net income gap ÷ (1 − tax rate).
Retirement drawdown: Each month uses New Balance = Old Balance × (1 + post-retirement return/12) − withdrawal.
Required retirement fund: The calculator reverses every modeled monthly withdrawal back to retirement start to estimate the minimum target balance.
Enter your current age, target retirement age, and life expectancy. These values define the saving period and the modeled retirement period.
Add your current savings and monthly contribution. Use the annual contribution increase field for planned raises or higher future saving rates.
Enter expected annual returns before retirement and during retirement. Then enter inflation to reflect rising living costs.
Provide your desired monthly retirement income in today’s money. Add any pension, rental income, or other monthly amount expected at retirement.
Enter the estimated tax rate on withdrawals. Submit the form to view your required fund, projected balance, income gap, yearly projection table, and chart.
This calculator focuses on the full retirement path instead of a single future value figure. It shows how saving years, contribution growth, inflation, taxes, portfolio returns, and spending needs connect to each other. That makes planning more realistic.
Many people estimate retirement by picking one target number. That shortcut can miss important details. Spending usually rises over time, taxes reduce usable withdrawals, and other retirement income sources may lower the portfolio burden. This calculator brings those moving parts together.
The saving phase uses monthly compounding and supports rising annual contributions. That helps model real behavior, especially when someone expects income growth before retirement. The retirement phase then tests whether the portfolio can keep up with withdrawals across the full life expectancy range.
The yearly projection table helps identify where a plan becomes stronger or weaker. The chart makes the path easier to understand. Export tools also make it easier to save results, compare scenarios, or discuss outcomes with family members or financial professionals.
You can test higher savings, lower retirement spending, delayed retirement, different return assumptions, or added income from pensions. Small changes often create large long-term effects. Using several scenarios usually gives a better planning view than relying on one estimate alone.
It estimates your retirement balance, required fund, monthly portfolio withdrawal, projected longevity of savings, and yearly balance path from today through life expectancy.
Inflation shows how much more income you may need later. A retirement target that looks comfortable today may become too small after several decades.
Portfolio growth often differs before and after retirement. Saving years may be more growth-oriented, while retirement years may use more conservative allocations.
It is income expected when retirement begins, such as pension payments, annuities, rent, or part-time work. It reduces the amount your portfolio must supply.
Taxes reduce spendable withdrawals. If you need a certain net income, the portfolio may need to distribute more than that amount before taxes.
Coverage ratio compares projected retirement savings with the estimated required fund. A value above 100% suggests your projected balance covers the modeled need.
Try increasing contributions, delaying retirement, lowering retirement spending, improving other income sources, or using more conservative withdrawal expectations.
Yes. Change one assumption at a time and compare results. That approach helps show which variables most influence retirement readiness.
