The 25x rule says you need roughly 25 times your annual spending saved to retire comfortably, which is the inverse of a 4% withdrawal rate. If you expect to draw $40,000 a year from your portfolio after Social Security and other income, your target is about $1 million; need $60,000, and the goal climbs to $1.5 million. The math is a planning shortcut, not a guarantee, because it assumes a roughly 30-year retirement and steady returns. This calculator applies the 25x rule automatically: it subtracts your Social Security and other income streams from your spending, multiplies the remaining gap by 25, and compares it to your projected portfolio to produce a readiness score. Enter your numbers to see your personal target and how close your current savings rate gets you to it.

A Monte Carlo simulation tests your plan against many possible market outcomes instead of assuming one fixed return every year, which never happens in reality. Two retirees with the same average return can end up very differently depending on whether a downturn hits early or late, so a single straight-line projection can be misleadingly optimistic. This calculator runs 400 simulations, applying random swings to your expected return during both your saving years and retirement, then reports the percentage of scenarios in which your money lasts. Planners generally treat an 85% or higher success rate as comfortable and anything under 70% as high-risk. You also see worst-case, median, and best-case ending balances rather than one number. Adjust your savings rate, retirement age, or spending and watch the success rate respond to find a plan that holds up across market conditions.

The 4% rule is a guideline that says withdrawing 4% of your portfolio in your first year of retirement, then adjusting that dollar amount for inflation each year after, gives your savings a strong chance of lasting about 30 years. On a $1 million portfolio that is $40,000 the first year. The rule comes from historical market research and is a starting point, not a promise. This calculator lets you choose the 4% rule, a variable 3 to 5% rate, or a fixed dollar amount, and it shows your actual withdrawal rate based on the income gap your portfolio must cover. When that rate climbs above 4.5%, the tool flags it because the risk of running out of money rises sharply beyond that point. Compare strategies side by side to find a sustainable withdrawal level for your situation.

Using 2024 IRS limits, you can contribute up to $23,000 to a 401(k) and $7,000 to an IRA, whether Traditional or Roth, with an HSA capped at $4,150. Once you reach age 50, catch-up contributions raise those ceilings to $30,500 for a 401(k) and $8,000 for an IRA, giving older savers room to accelerate. This calculator tracks each account against its limit with a contribution-utilization bar so you can see how close you are to maxing out, and it switches on catch-up limits automatically at 50. It also models employer matching as additional annual savings and flags it as free money you should not leave on the table. Add your accounts, enter your monthly contributions, and the tool shows whether you are fully using your tax-advantaged space or have room to save more.

Required minimum distributions, or RMDs, are mandatory withdrawals the IRS forces from tax-deferred accounts like a Traditional 401(k) or Traditional IRA once you reach age 73. They exist because those accounts grew tax-deferred, and the government eventually wants its share. The amount is calculated by dividing the account balance by an IRS life-expectancy factor, so it grows as a percentage of your balance as you age. Missing an RMD historically carried a steep penalty on the amount you failed to take. Roth IRAs are not subject to RMDs during the original owner's lifetime, which is one reason savers value them. This calculator estimates your first RMD at age 73 by projecting your Traditional balance forward, helping you anticipate the taxable income it adds. Model your accounts to see how RMDs affect your retirement tax picture.
