A Retirement Calculator is a financial tool to estimate how much money you’ll need at retirement to ensure a steady income throughout non-working years. It considers your current age, planned retirement age, savings, and expected investment returns.
By inputting your financial details, you get a step-by-step calculation of the lump sum needed, inflation-adjusted, to maintain your desired lifestyle. The calculator projects whether your current savings and contributions align with your retirement go
The core formula estimates the future value of your investments: FV = PV × (1+r)n + PMT × [( (1+r)n – 1 ) / r ], adjusting for inflation. The required corpus is computed as the present value of inflation-adjusted income during retirement years.
| Sample Input | Projected corpus needed ₹ | Monthly Savings Required ₹ |
|---|---|---|
| Age 30, 2 lakhs saved, 10k/month, retire at 60, want 50k/month | 2,40,44,000 | 10,000 |
| Age 40, 5 lakhs, 12k/month, retire at 60, want 60k/month | 6,96,81,1000 | 19,500 |
| Age 35, 3 lakhs, 5k/month, retire at 58, want 40k/month | 1,12,40,000 | 7,300 |
This tool gives you a quick, accurate, and visual roadmap for retirement, personalized to your real-life inputs. It is entirely free, easy to use on any mobile device, and ensures you consider critical factors like inflation and returns.
