❓ Frequently Asked Questions

How much retirement corpus do I need? +
A common rule is 25× your annual expenses (4% withdrawal rule). Inflation-adjusted calculators like ours give more accurate figures based on your specific situation.
What is the 4% withdrawal rule? +
Research shows you can safely withdraw 4% of your corpus annually in retirement without depleting it over 30 years, assuming balanced investment returns.
Should I account for inflation in retirement planning? +
Absolutely. Inflation of 5% means your expenses double every 14 years. A plan that ignores inflation will fall dangerously short.
At what age should I start planning retirement? +
Start at 25 if possible. Thanks to compounding, investing $200/month from age 25 builds a larger corpus than $500/month starting at 40.

Why Retirement Planning Starts Today — Not Later

Retirement planning is the single most important long-term financial decision you will make, yet most people delay starting it. The reason to start immediately — regardless of your age or income — is compounding. Every year you delay costs you far more than just one year of contributions.

If you start investing $300/month at age 25 and stop at 35 (investing for only 10 years, contributing $36,000 total), at 8% annual returns you will have approximately $472,000 by age 65. If instead you start at 35 and invest $300/month for 30 years ($108,000 total), you will have approximately $408,000. The person who invested less, earlier, ends up with more money. This is the extraordinary power of compounding time.

How Much Do You Need to Retire?

The most widely used retirement planning framework is the 4% Rule. It states that if you withdraw 4% of your retirement portfolio in year one, then adjust for inflation annually, your money should last at least 30 years with high probability.

This means to retire comfortably, you need a portfolio of roughly 25 times your annual retirement expenses. If you need $40,000/year to live comfortably, your target retirement corpus is $1,000,000. Use our calculator above to see how monthly contributions and investment returns affect when you can reach your target.

Keep in mind that retirement expenses differ from current expenses — you may spend less on commuting, work clothes, and mortgage (if paid off), but more on healthcare and leisure. Many planners use 70–80% of current income as the retirement income target.

Retirement Savings Vehicles Around the World

USA: 401(k) and IRA. Employer-sponsored 401(k) plans allow pre-tax contributions up to $23,000/year (2024), reducing your taxable income now. Many employers match contributions — always contribute enough to capture the full match, as it is essentially free money. Roth IRA allows after-tax contributions with tax-free growth and withdrawals.

India: EPF, NPS, and PPF. Employee Provident Fund (EPF) deducts 12% of basic salary automatically and is employer-matched. National Pension System (NPS) offers additional tax benefits and flexible investment options. PPF offers tax-free returns with a 15-year horizon.

UK: Workplace Pension. Auto-enrollment means all eligible employees are automatically enrolled. Minimum total contributions are 8% of qualifying earnings (employee + employer combined).

Global principle. Regardless of country, the principle is the same: start early, contribute consistently, maximize employer matching, and increase contributions as income grows.

The Impact of Inflation on Retirement

Inflation is retirement planning's silent enemy. If inflation averages 3% per year, your purchasing power halves in approximately 24 years. This means the $50,000/year you plan to live on at retirement may feel like only $25,000 in purchasing power 24 years into retirement.

This is why your retirement portfolio must continue growing even after you retire — keeping a portion in growth assets like equities or index funds, not just bonds and fixed deposits. A portfolio of 60% equities and 40% bonds is a common starting point for retirees, gradually shifting more conservative over time.

Always factor an assumed inflation rate of 3–4% into your retirement projections. Our calculator accounts for this so your estimated corpus reflects real purchasing power, not just nominal figures.
