Free financial calculators and wealth planning tools designed for Indian investors. Calculate SIP returns, estimate income tax, plan your retirement, and set investment goals — all in one place.
SIP & Lumpsum Investment Calculator
Calculate the future value of your Systematic Investment Plan (SIP) or lumpsum investment. This tool accounts for expected returns and inflation to show your real purchasing power.
Income Tax Calculator (New Regime 2025-26)
Estimate your income tax liability under the New Tax Regime as per Union Budget 2025-26 rules. The new regime offers a standard deduction of &rupee;75,000 and revised tax slabs with lower rates.
How it works: Under the New Regime, a standard deduction of &rupee;75,000 is applied to your gross salary. If taxable income is up to &rupee;12,00,000, no tax is payable (rebate under Section 87A). For income above &rupee;12,00,000, slab rates of 5%, 10%, 15%, 20%, and 30% apply progressively. A 4% Health and Education Cess is added to the final tax amount.
Capital Gains Tax Calculator
Calculate tax on your equity investment profits. Long-term capital gains (LTCG) on listed equities held over 1 year are taxed at 12.5% above &rupee;1.25 lakh exemption. Short-term gains (STCG) on equities held less than 1 year are taxed at 20%.
Retirement SWP (Systematic Withdrawal Plan) Calculator
A Systematic Withdrawal Plan lets retirees draw a fixed monthly income from their mutual fund corpus. This calculator estimates how long your retirement corpus will last at an assumed 8% annual return, given your chosen monthly withdrawal amount.

Understanding the Power of Compounding in Mutual Fund Investments
Compounding is the process where the returns you earn on an investment also begin to earn returns of their own. When you invest in a mutual fund through a Systematic Investment Plan (SIP), each monthly installment starts earning returns immediately. Over time, these accumulated returns generate their own returns, creating an exponential growth curve that is often called the "snowball effect" of investing.
How SIP Compounding Works
Consider a practical example: If you invest &rupee;10,000 per month in a diversified equity mutual fund that delivers an average annualized return of 12%, here is how your wealth grows over different time periods:
| Duration | Total Invested | Estimated Corpus | Returns Earned |
|---|---|---|---|
| 5 Years | &rupee;6,00,000 | &rupee;8,25,000 | &rupee;2,25,000 |
| 10 Years | &rupee;12,00,000 | &rupee;23,50,000 | &rupee;11,50,000 |
| 20 Years | &rupee;24,00,000 | &rupee;1,00,00,000 | &rupee;76,00,000 |
| 30 Years | &rupee;36,00,000 | &rupee;3,53,00,000 | &rupee;3,17,00,000 |
Notice how the returns earned in the last 10 years (from year 20 to year 30) are nearly three times the entire invested amount. This is the real power of compounding — the longer you stay invested, the more dramatic the growth becomes.
The Impact of Inflation on Your Returns
While compounding grows your wealth, inflation quietly erodes the purchasing power of your money. If inflation averages 6% per year, a &rupee;1 Crore corpus accumulated after 20 years of SIP investment will only buy what approximately &rupee;31 Lakhs can buy in today's terms. This is why SmartInvest Pro calculates the Real Rate of Return, which adjusts for inflation to show you the actual purchasing power of your future wealth.
The real rate of return is calculated as: Real Return = ((1 + Nominal Return) / (1 + Inflation Rate)) - 1. For example, if your fund returns 12% and inflation is 6%, your real return is approximately 5.66%, not 6%. Understanding this distinction is essential for setting realistic financial goals.
Key Takeaways for Indian Investors
- Start early: Even a small SIP of &rupee;2,000-5,000 per month can grow into a substantial corpus over 20-30 years thanks to compounding.
- Stay consistent: Rupee cost averaging through SIP means you buy more units when markets are low and fewer when markets are high, smoothing out volatility over time.
- Think long-term: The real magic of compounding happens after the 10-year mark. Patience is the most powerful tool in an investor's toolkit.
- Account for inflation: Always factor in inflation when planning for goals like retirement, children's education, or buying a home.
Complete Guide to Income Tax Under the New Regime (FY 2025-26)
The Union Budget 2025-26 brought significant changes to India's income tax structure under the New Tax Regime. Here is everything you need to know about calculating your tax liability, understanding the new slabs, and deciding whether the new regime works for you.
New Tax Regime Slabs for FY 2025-26
| Taxable Income Slab | Tax Rate |
|---|---|
| Up to &rupee;4,00,000 | Nil |
| &rupee;4,00,001 - &rupee;8,00,000 | 5% |
| &rupee;8,00,001 - &rupee;12,00,000 | 10% |
| &rupee;12,00,001 - &rupee;16,00,000 | 15% |
| &rupee;16,00,001 - &rupee;20,00,000 | 20% |
| &rupee;20,00,001 - &rupee;24,00,000 | 25% |
| Above &rupee;24,00,000 | 30% |
Key Features of the New Tax Regime
- Standard Deduction: A standard deduction of &rupee;75,000 is available for salaried employees and pensioners.
- Tax Rebate: Under Section 87A, if your total taxable income (after standard deduction) does not exceed &rupee;12,00,000, your entire tax liability is waived — effectively making income up to &rupee;12,75,000 tax-free for salaried individuals.
- Health & Education Cess: A 4% cess is levied on the calculated tax amount.
- No exemptions: Most exemptions and deductions (like 80C, 80D, HRA) are not available under the new regime. This simplifies filing but may not suit taxpayers with significant deduction claims.
Example Calculation
For a salaried individual earning &rupee;15,00,000 per year:
- Gross Salary: &rupee;15,00,000
- Standard Deduction: &rupee;75,000
- Taxable Income: &rupee;14,25,000
- Tax on &rupee;4,00,001 - &rupee;8,00,000 at 5% = &rupee;20,000
- Tax on &rupee;8,00,001 - &rupee;12,00,000 at 10% = &rupee;40,000
- Tax on &rupee;12,00,001 - &rupee;14,25,000 at 15% = &rupee;33,750
- Total Tax: &rupee;93,750
- Plus 4% Cess: &rupee;97,500

Capital Gains Tax on Equity Investments in India: What Every Investor Should Know
When you sell shares or equity mutual fund units at a profit, the gains are subject to capital gains tax. The tax treatment depends on how long you held the investment.
Long-Term Capital Gains (LTCG) on Equities
If you hold listed equity shares or equity-oriented mutual fund units for more than 12 months before selling, the profit qualifies as long-term capital gain. As per current tax rules:
- LTCG up to &rupee;1,25,000 in a financial year is fully exempt from tax.
- LTCG above &rupee;1,25,000 is taxed at a flat rate of 12.5% (plus applicable cess).
- No indexation benefit is available for listed equity LTCG.
Short-Term Capital Gains (STCG) on Equities
If you sell your equity investments within 12 months of purchase, the profit is classified as short-term capital gain and taxed at a flat rate of 20% (plus cess), irrespective of your income tax slab.
Tax-Saving Tips for Equity Investors
- Hold for the long term: By holding for more than 12 months, you benefit from the lower LTCG rate of 12.5% instead of the 20% STCG rate, plus the &rupee;1.25 lakh annual exemption.
- Harvest gains annually: Consider booking profits up to &rupee;1.25 lakh each year to take advantage of the LTCG exemption limit. This technique, called "tax-loss harvesting," can help reduce your overall tax burden over the years.
- Use ELSS funds: Equity Linked Savings Schemes offer tax deduction under Section 80C (in the old regime) along with equity market exposure, though they come with a 3-year lock-in period.
Retirement Planning in India: Building a Sustainable Withdrawal Strategy
Retirement planning is one of the most critical aspects of financial management, yet it is often the most overlooked. Many Indians depend primarily on their provident fund and pension, which may not be sufficient to maintain their pre-retirement lifestyle, especially considering rising healthcare costs and increasing life expectancy.
What is a Systematic Withdrawal Plan (SWP)?
A Systematic Withdrawal Plan allows retirees to withdraw a fixed amount from their mutual fund investment at regular intervals (usually monthly) while the remaining corpus continues to earn returns. Unlike a fixed deposit that offers a fixed interest rate, an SWP in a balanced or debt mutual fund can potentially deliver higher returns (typically 7-9% annually), making your retirement corpus last significantly longer.
How Long Will Your Corpus Last?
The sustainability of your retirement corpus depends on three key factors:
- Corpus size: The total amount you have accumulated at the time of retirement.
- Monthly withdrawal: The fixed amount you need each month for living expenses.
- Return on remaining corpus: The annual return your invested corpus continues to earn.
For example, with a &rupee;50 lakh corpus earning 8% annual returns and a monthly withdrawal of &rupee;30,000, your corpus would last approximately 25 years. Reduce the withdrawal to &rupee;25,000, and it could last over 38 years. Use the SWP calculator above to plan your specific scenario.
Tips for Building a Sufficient Retirement Corpus
- Start your SIP early: Beginning at age 25 instead of 35 can nearly double your retirement corpus thanks to the extra decade of compounding.
- Increase SIP annually: A step-up SIP where you increase your investment by 10% each year can dramatically accelerate wealth accumulation.
- Diversify your portfolio: Allocate across equity, debt, and hybrid funds based on your risk tolerance and retirement timeline.
- Plan for healthcare: Medical expenses tend to increase significantly after age 60. Ensure you have adequate health insurance and a dedicated medical emergency fund.
