Retirement Calculator — A Spending Plan for Your Next Chapter
Connect the money you save today with the life you want after work. Estimate your target fund, solve a monthly saving amount, test a retirement budget or see when a spending shortfall begins.
Planning estimate in Indian rupees. All rates are editable assumptions. A result does not guarantee that savings will last for life.
Retirement Calculator
Choose a mode, then set your retirement assumptions.
Where the money goes
The spending fund excludes your separate reserve. A shortfall is an unfunded expense, not a negative bank balance.
| Period | Contributions | Model growth | Closing savings |

| Period | Expenses | Pension / income | Funded withdrawals | Unfunded expenses | Closing spending fund |

Two phases. One explicit model.
The inputs describe a scenario rather than a product recommendation.
Before retirement
Existing savings compound monthly. A fixed contribution is added at each month-end; it does not rise with salary or inflation.
After retirement
Living costs rise monthly at the annual inflation assumption. Pension offsets that month’s expenses. Any positive gap is withdrawn at month-end, after model growth.
Corpus and saving
The living corpus is the present value of each positive monthly spending gap. Add the separate reserve to get the target; Monthly Saving solves the fixed contribution needed to reach it.
Budget and runway
Retirement Budget solves a first-month household spending limit, with later spending rising by inflation. Fund Runway counts fully funded months up to your chosen end age; it does not predict lifespan.
Monthly factor = (1 + annual rate / 100)1/12. First-month retirement expense = today’s monthly expense × (1 + inflation / 100)years to retirement. Living corpus = Σ max(expensek − incomek, 0) / return-factork. Returns are nominal annual effective rates; no separate inflation subtraction is applied. Extra pension income is not invested.
A zero-rate example you can check by hand
Illustration only: retire now at 60, plan to 80, no inflation, no return and no pension.
The spending requirement
₹30,000 a month for 240 months needs ₹72,00,000 for living costs. A ₹5,00,000 separate reserve makes the total target ₹77,00,000.
The pension difference
With spendable pension of ₹10,000 a month and no pension increases, the monthly gap becomes ₹20,000. Living corpus is ₹48,00,000; including the same reserve, target is ₹53,00,000.
Start with your household situation
An account balance and a reliable monthly income solve different parts of the plan.
| Your situation | Input choice | What to check |
|---|---|---|
| I will retire soon | Use Fund Runway | Check spendable balances and the first shortfall; reducing the saving horizon limits the impact of new contributions. |
| I have no fixed pension | Enter pension as zero | Do not assume EPF, NPS or a future annuity gives a specific monthly benefit without a separate verified estimate. |
| My spouse retires later | Use a combined scenario carefully | This model has one retirement start and one income-growth path. Staggered incomes, survivor benefits and changing household costs need separate scenarios. |
| My home is my largest asset | Exclude it from existing savings | It is not spendable investment money unless your plan explicitly converts it to available cash. Future rent or sale proceeds are not modeled. |
| I want an emergency fund and inheritance | Use the separate reserve | The reserve is held outside the spending model in retirement-date rupees. It is not a simulation of future emergencies or a guaranteed bequest. |
Build a retirement file before choosing investments
Gather the records that let you enter usable figures.
Audit your spending
Review 12 months of household costs. Separate recurring expenses from a home purchase, wedding or other one-off commitments; those cash flows are not scheduled here.
Reconcile your balances
Use current EPF, NPS, PPF, deposit and investment statements. Count each available balance once and check when it can actually be accessed.
Verify your income
Keep pension statements, annuity quotes and rental records. Enter spendable income after your allowance for costs and tax, without treating a quote as a guaranteed entitlement.
Test the fragile assumptions
Repeat the calculation with a lower post-retirement return, higher spending inflation and a later end age. Review health insurance and reserves separately; this tool does not price insurance or medical treatment.

Plan early and leave room for emergencies
SEBI’s investor education explains the value of early saving, emergency provision, insurance and diversification. The reserve input makes one part of that planning visible. Read SEBI’s retirement guidance ↗
Use purchasing power, not just rupees
SEBI explains that inflation reduces what money can buy. This calculator therefore grows expenses through both the saving and retirement phases. Read SEBI’s inflation explanation ↗

Honest by Design
Know what the number means before using it to make a decision.
What this calculator does
Models monthly saving and retirement spending with editable constant returns, inflation, pension growth and a finite end age. Shows shortfalls and a separate reserve explicitly.
What it does not do
Does not simulate market volatility, sequence-of-returns risk, longevity probabilities, tax law, annuity eligibility, EPF/NPS withdrawal conditions, benefit revisions or changing income start dates.
What a funded result means
The chosen expenses are covered through your chosen end age only under the entered assumptions. It is not a probability of success or a lifetime-income guarantee. Inputs are processed in this calculator’s browser code; they are not uploaded by this code.
Retirement planning questions
Answers about this calculator’s scope and assumptions.
Is the target corpus an exact amount?
No. It is the amount required by the selected mathematical scenario. Changes in inflation, returns, spending or retirement length change the result.
Which return should I enter?
Use a nominal annual effective scenario after your allowance for fees and taxes. The calculator does not recommend a rate or deduct tax automatically. Default rates are examples.
Can I use this if I am already retired?
Yes. Set current age and retirement age to the same whole-year age and enter current spendable savings. Monthly Saving needs a future retirement age; the other modes support immediate retirement.
Why is my emergency reserve excluded from the chart?
The model sets it aside at retirement. It is not invested, withdrawn or inflated afterward in this calculation. If projected savings cannot cover it, the result flags the reserve shortfall.
Why can pension be greater than a month’s expenses?
The model shows the full pension but withdraws only a positive spending gap. Surplus pension is not saved into the fund, so a larger pension does not automatically create a larger balance.
Does a full-horizon result mean I can retire safely?
It means the entered cash flows are funded to the selected end age in a constant-return model. Real markets, health costs and household circumstances can differ; review those separately.
