Retirement Calculator
Plan every milestone — home, education, marriage, retirement — on one financial timeline. Inflation-adjusted & multi-goal.
Monthly expenses are inflated yearly to estimate retirement income needs.
About the Retirement & Life Roadmap Calculator
Most retirement calculators answer one narrow question: "how much do I need by 60?" Real life isn't that simple. Between now and retirement you'll buy a home, fund your children's education and marriage, travel, perhaps start a business — each pulling money from the same savings pool. This Retirement & Life Roadmap Calculator models your entire life journey as a single integrated plan. Use Age-Range Phases to model realistic retirement spending — for example, higher travel expenses at 60–70, then lower expenses at 70+ — while the year-by-year simulation shows exactly when your corpus is under pressure.
How to Use
- Enter your current age, retirement age, and life expectancy.
- Add your current savings, monthly investment, return and inflation rates.
- Choose Single Amount for a fixed monthly expense, or Age-Range Phases to define different spending at different life stages (e.g. ₹50K/mo at 60, ₹1.5L/mo at 70).
- Edit the pre-filled life goals or add your own — each in today's money.
- Click Build My Roadmap to see corpus trajectory, goal feasibility, and retirement sustainability.
Formula Used
The corpus grows month-by-month. In age-range mode, each year's withdrawal is determined by whichever phase is active — the monthly amount (in today's value) is inflated from today's age to the simulation year. All amounts are in today's money; the calculator inflates automatically.
Why goal-based planning beats a single retirement number
Frequently Asked Questions
What is a life roadmap or financial roadmap?
A financial roadmap maps every major money milestone — buying a home, funding education, marriage, starting a business, retirement — onto a single timeline. Instead of planning each goal in isolation, you see how each affects the others, allowing trade-offs and prioritisation.
How does inflation affect long-term goals?
At 5% inflation, a goal costing $100,000 today will cost $163,000 in 10 years and $432,000 in 30 years. Without adjusting for inflation, every long-term plan is dramatically under-funded. This calculator inflates each goal from today's value to its target year automatically.
What if my corpus runs out before my life expectancy?
The calculator flags this as "Plan needs strengthening." Fixes: increase monthly investments (highest impact), retire later (cuts both accumulation gap and decumulation period), reduce target amounts on flexible goals (dream vacation, new business), or improve returns by shifting more allocation to equity early in life.
How is this different from a generic retirement calculator?
A generic retirement calculator gives one number — the corpus you need at retirement. This roadmap models every withdrawal between now and life expectancy, so a $400k home purchase at 40 properly resets your compounding curve. The output is a year-by-year corpus trajectory, not a single magic number.
Can I use this for early retirement (FIRE) planning?
Yes. Set retirement age to your target (40, 45, 50) and life expectancy to 90+. The calculator will model 40–50 years of decumulation. The "Safe Monthly Income (4% rule)" stat is the FIRE community's standard sustainability benchmark — if it covers your inflated expenses, you have FI (financial independence).
What return rate and inflation should I use?
Use long-term averages for your region. Equity-heavy portfolios: US/global ~7–10%, India ~10–12%. Balanced: 6–8%. Inflation: US/UK/EU ~2–3%, India ~5–6%, emerging markets ~4–7%. Use conservative numbers — over-estimating returns is the #1 cause of failed retirement plans.
Why use age-range expense phases?
Real retirement spending isn't flat. Active early retirees often spend more; later years see lower discretionary spending. For example: ₹50,000/mo at ages 60–70 for travel, ₹1,50,000/mo at 70–80 for healthcare, ₹1,00,000/mo at 80+ for basic needs. Modelling phases prevents both over-saving and under-planning.
Important Note
This calculator assumes constant returns and inflation, which real markets rarely deliver. Use the year-by-year breakdown as a directional plan, then stress-test with lower returns and higher inflation to find your safety margin. For complex situations (multiple income streams, business equity, foreign-currency goals), consult a qualified financial planner.
