Retirement planning is the most consequential financial journey of your life. A 25-year-old who invests $500/month at 7% will accumulate over $1.3 million by age 65 - the same person starting at 35 builds only $610,000. Time is the most powerful ingredient in retirement math. Use these calculators to model your accumulation, plan your income, and test withdrawal strategies.

The 401k Calculator projects balance at retirement with employer match and compound growth (the 2024 employee contribution limit is $23,000, $30,500 with catch-up) - always contribute at least enough to capture the full employer match, since it is an immediate 50-100% return. The IRA and Roth IRA Calculators compare pre-tax versus tax-free growth side by side, with the 2024 IRA limit at $7,000 ($8,000 age 50+) and Roth income phase-outs starting at $146,000 (single).

The eight annuity calculators cover every direction of the same core time-value-of-money math: the Annuity Calculator is the foundational tool for ordinary annuities and annuities-due, while the Future Value and Present Value of Annuity Calculators isolate each direction specifically for 401(k)/IRA projections and pension valuations respectively. The Immediate and Deferred Annuity Calculators model the two ways an insurance annuity converts a lump sum into income - immediately, or after an accumulation phase. The Growing and Variable Annuity Calculators add complexity real products have: payments that escalate over time, or returns that vary with market scenarios net of insurer fees.

The Retirement Calculator is the comprehensive readiness tool, scoring your projected nest egg against your income goal as a percentage. The Early Retirement (FIRE) Calculator applies the same 25x-expenses logic to a much shorter accumulation window. The Retirement Withdrawal and Savings Withdrawal Calculators solve the decumulation side - how long money lasts, or what withdrawal rate a balance can sustain indefinitely. The Rule of 72 Calculator is the fast mental-math shortcut behind all of the above: divide 72 by your return rate to estimate doubling time. The NPS Calculator is the India-specific tool, covering the mandatory 40% annuitization rule, 60% tax-free lump sum, and the Section 80CCD(1B) additional deduction unique to India’s National Pension System.

Who Uses These Calculators

Salaried employees in the US use the 401(k), IRA, and Roth IRA calculators to optimize contribution strategy and employer match capture. Financial planning clients and DIY retirement planners use the comprehensive retirement calculator and FIRE calculator to set and track a target nest egg. Retirees and near-retirees use the withdrawal calculators to structure a sustainable decumulation strategy and avoid outliving their savings. Insurance agents and annuity buyers use the eight annuity calculators to compare immediate versus deferred products and evaluate variable annuity fee drag. Indian salaried employees and NPS subscribers use the NPS calculator for Tier I corpus projection and tax deduction planning under Section 80CCD(1B).

Frequently Asked Questions

How much do I need to retire comfortably?

The 25x rule: multiply your annual expenses by 25 (based on the 4% safe withdrawal rate). If you spend $60,000/year, you need $1.5 million. Factor in Social Security income - a $2,000/month benefit reduces the required portfolio by $600,000 at 4% SWR. Use the Retirement Calculator to run your specific numbers.

Should I choose a 401k, Traditional IRA, or Roth IRA?

Max your 401k to capture the full employer match first - that's an immediate return. Then decide between Traditional and Roth IRA based on your current vs. expected retirement tax rate. Roth is generally better for younger, lower-bracket workers; Traditional may be better for high earners in peak earning years. Many advisors recommend both for tax diversification. Compare outcomes with the IRA Calculator and Roth IRA Calculator.

What is the 4% safe withdrawal rate?

William Bengen's 1994 research found that a 50/50 stock/bond portfolio could sustain a 4% annual withdrawal (inflation-adjusted) for at least 30 years through any historical market cycle. For early retirees needing 40–50 years, use 3–3.5%. Test your specific situation with the Retirement Withdrawal Calculator.

How does employer matching work in a 401k?

A common match formula is "50% of contributions up to 6% of salary." On an $80,000 salary contributing 6% ($4,800), the employer adds $2,400 - a 50% immediate return on that money. Never leave employer match on the table. Use the 401k Calculator to see how match accelerates your balance.

What is the FIRE number?

Your FIRE (Financial Independence, Retire Early) number is 25x your annual expenses - the portfolio size that sustainably funds your lifestyle at a 4% withdrawal rate. For $50,000/year in expenses, the FIRE number is $1,250,000. Use the Early Retirement Calculator to find your number and years to reach it.

What is the difference between an immediate and a deferred annuity?

An immediate annuity (SPIA) starts paying income right away - typically within a month of the lump-sum purchase - and is used to convert a retirement lump sum directly into guaranteed lifetime income. A deferred annuity has an accumulation phase first, where the lump sum grows tax-deferred for years or decades, followed by a payout phase that starts later, usually at retirement. Use the Immediate Annuity Calculator if you need income now, and the Deferred Annuity Calculator if you are purchasing years before you need the income to start.

How does the NPS 60% tax-free rule work at retirement?

India's National Pension System requires that at least 40% of the accumulated corpus be used to purchase an annuity providing regular pension income; the remaining 60% can be withdrawn as a lump sum, and that lump sum is entirely tax-free under current rules. The annuity portion is taxed as regular income when received. The NPS Calculator models both pieces together - the tax-free lump sum and the resulting monthly annuity income from the mandatory annuitized portion.
