Your Future Deserves More Than a SIP Calculator.

Most retirement planning tools tell you how much money you might accumulate. They do not tell you whether your retirement survives.

Traditional Calculator

  • Fixed assumptions
  • Single straight-line projection
  • Ignores market crashes
  • Ignores inflation uncertainty
  • No life event planning
  • No probability analysis

RetireOS

  • Dynamic simulations
  • Inflation modeling
  • Multiple asset classes (EPF, Stocks, Real Estate)
  • Withdrawal strategies
  • Manual life event overrides

Built Around Indian Financial Reality

Calculate your own unique inflation rate based on your lifestyle, rather than relying solely on generic government CPI and WPI numbers.

Provident Funds

Model EPF, VPF, and PPF as custom asset classes with tax-free compounding rates.

Pension Schemes

Track NPS accumulation and map it as a custom retirement asset.

Equity & Funds

Simulate Direct Equity, Mutual Funds, and ELSS with volatile accumulation phases.

Real Estate

Model physical property (House, Flat, Land, Farm House) and REITs with yield growth.

Fixed Income

Add Fixed Deposits as stable, predictable income sources and emergency buffers.

Employee Benefits

Project the vesting schedule and valuation of your RSUs and ESOPs over time.

Alternatives

Include Gold and other alternative assets in your diversified long-term portfolio.

Cash Buffers

Plan multi-year liquid buffers to survive severe market downturns without selling equity.

How It Works

Build at your own pace, plan, iterate and improve

Step 1: Build your custom model

Add your income streams, custom asset classes, and upcoming life events. Create a comprehensive picture without dealing with complex spreadsheet formulas.

Step 2: Stress-test your assumptions

What if your personal inflation rate is higher? What if you take a career break at 45? Adjust your inputs manually and see the impact instantly.

Step 3: Visualize your timeline

Track your projected net worth year-over-year. See exactly when your corpus peaks or starts depleting based on your unique numbers and lifestyle choices.

Questions RetireOS Helps You Answer.

What happens if I take a 2-year career break at age 45?

→ "Add a 'Career Break' life event and watch your projected net worth chart adjust instantly."

How does 8% inflation affect my retirement runway compared to 6%?

→ "Change your personal inflation rate and see exactly how many years it shaves off your corpus."

At what age will my money run out if my expenses double later?

→ "Model a custom expense life event and visualize the exact age your net worth drops to zero."

How does changing my asset allocation change my trajectory?

→ "Adjust the returns on your custom asset classes and see your new portfolio peak."

Watch a Retirement Plan Come Alive.

This is what clarity looks like.

A Note from the Founding Team

We developed RetireOS because we saw a massive gap in how Indians plan for their financial independence.

Most tools available today are either generic calculators that ignore the realities of Indian inflation and asset classes, or they are lead-generation traps built by institutions trying to cross-sell you products you don't need.

We wanted something different. A tool that provides absolute clarity on exactly when you can stop working. A tool that respects your privacy—running entirely in your browser so your sensitive financial data is stored as encrypted objects and never goes to a database.

We built the exact tool we needed for our own retirement planning. We hope it brings you the same peace of mind it brought us.

Frequently Asked Questions

Is my financial data safe?
Your data is encrypted at rest and processed locally. We never sell or share your financial data with third parties. We have no advertising partners.
What if it's not right for me?
Not for you? Full refund within 7 days — no questions asked.
What makes RetireOS different from retirement calculators?
Traditional calculators use a single, straight-line assumption for growth and inflation. RetireOS is a dynamic simulation engine that allows you to model real-life complexity: market crashes, varying inflation, specific life events (like buying a house or sending a kid to college), and multiple distinct asset classes simultaneously.
Can I model EPF and PPF?
Yes. RetireOS specifically includes parameters for Indian sovereign debt instruments, allowing you to model employer matches, compounding interest, and withdrawal rules unique to EPF and PPF.
