What is this Savings Calculator?
This free savings calculator uses the compound interest formula to show exactly how your money grows over time — taking into account your initial deposit, regular monthly contributions (SIP), the annual interest or return rate, years of saving, and compounding frequency. The result includes a year-by-year growth chart so you can visually see the difference between what you put in and what interest adds on top.
Whether you are planning a home down payment, your child's higher education, an emergency fund, or your retirement corpus, this tool helps you understand what monthly saving commitment is required to reach your goal — and how much compound interest will work in your favour over time.
How to use this Savings Calculator — step by step
- Step 1 — Select currency: Choose ₹ (Rupee) for India or another symbol if planning for international goals. The currency symbol only affects how results are displayed — it does not change the calculation.
- Step 2 — Initial amount: Enter how much you already have saved or will deposit at the start. This can be ₹0 if you are starting fresh, or your existing FD/savings balance.
- Step 3 — Monthly contribution (SIP): Enter how much you will add every month. This is equivalent to a monthly SIP for mutual funds, a recurring deposit, or any systematic monthly saving amount. Set to ₹0 if you are making a one-time deposit only.
- Step 4 — Annual interest rate: Enter the expected annual return. For reference: savings accounts offer 3–4%, FDs offer 6–7.5%, PPF offers 7.1%, and equity mutual funds have historically delivered 10–14% over long periods.
- Step 5 — Years to save: Enter how long you plan to stay invested — 1 to 50 years.
- Step 6 — Compound frequency: Choose how often interest is compounded. Monthly is standard for SIPs and savings accounts. Quarterly matches most Indian FDs. Daily compounding is used by some savings products and gives the highest return.
- Step 7 — Click "Calculate growth": Instantly see your Future Value (total corpus), Total Invested amount, and Interest Earned — plus a line chart showing growth year by year.
Real savings goal examples with this calculator
- Home down payment in 5 years: Initial ₹1,00,000 + ₹25,000/month at 7% monthly compounding for 5 years → Future value ≈ ₹20.7 lakh. Total invested = ₹16 lakh. Interest earned ≈ ₹4.7 lakh.
- Child's higher education in 18 years: Initial ₹50,000 + ₹10,000/month at 9% for 18 years → Future value ≈ ₹60 lakh. Total invested = ₹22.1 lakh. Interest earned ≈ ₹37.9 lakh — compound interest contributes more than your own savings.
- Emergency fund in 2 years: Initial ₹0 + ₹15,000/month at 6.5% for 2 years → Future value ≈ ₹3.83 lakh — a solid 6-month expense emergency fund for most urban families.
- Retirement corpus in 30 years: Initial ₹0 + ₹10,000/month at 10% for 30 years → Future value ≈ ₹2.26 crore on a total investment of only ₹36 lakh. The remaining ₹1.9 crore is pure compound interest.

The power of compound interest — and the savings mistakes that waste it
Albert Einstein reportedly called compound interest the "eighth wonder of the world." Whether or not he said it, the math backs it up. Compound interest means your interest earns interest — and over decades, this creates an exponential snowball effect where the growth curve bends sharply upward. The problem is that this effect is invisible in the short term and therefore easy to underestimate. Most Indians who fall short of their financial goals do not fail because of low income — they fail because they start late, stop during market dips, choose low-return products, or never calculate what they actually need to save each month to hit their target.
Simple interest vs compound interest — the critical difference
With simple interest, you earn the same fixed amount every year. ₹1,00,000 at 8% simple interest for 20 years grows to ₹2,60,000. Your interest is always 8% of the original ₹1,00,000 = ₹8,000/year.
With compound interest (monthly), the same ₹1,00,000 at 8% for 20 years grows to ₹4,92,680 — nearly double. Why? Because in Year 2, you earn 8% not just on ₹1,00,000 but on ₹1,08,299 (your balance after Year 1). By Year 20, you are earning 8% on ₹4.56 lakh. The base keeps growing, and so does the interest. This calculator shows this curve precisely on the chart — notice how the gap between the blue line (total value) and the green line (contributions) widens dramatically in later years.
The 5 biggest savings mistakes Indians make
Starting 10 years late
This is the single most expensive mistake in personal finance. Consider two people: Anita starts saving ₹5,000/month at age 25. Ravi starts ₹5,000/month at age 35. Both stop at age 60. At 10% returns, Anita retires with ₹1.91 crore. Ravi retires with ₹66 lakh — despite investing for 25 years vs Anita's 35. Those 10 extra years of compounding are worth over ₹1.25 crore. No raise, no investment trick, no side hustle can compensate for starting 10 years late.
Keeping everything in a savings account
A standard savings account in India offers 3 to 4% interest — lower than the CPI inflation rate of 5 to 6%. This means money kept in a savings account is actually losing purchasing power every year in real terms. ₹10 lakh in a savings account at 3.5% for 20 years grows to ₹19.9 lakh. The same amount at 10% (equity mutual fund historical average) grows to ₹67.3 lakh. The difference is ₹47.4 lakh — from choosing the right savings vehicle.
Stopping SIPs during market dips
When markets fall 20 to 30%, the instinct is to stop SIPs to "wait for stability." This is mathematically backwards. When your SIP buys units at lower NAV during a dip, you accumulate more units — and those units multiply in value during the eventual recovery. Studies of Nifty SIP data consistently show that investors who continued SIPs through the 2008, 2020, and other crashes significantly outperformed those who paused. Consistency beats timing every single time.
Not increasing SIP with income
A flat ₹5,000/month SIP has less real value every year as inflation erodes purchasing power. Most financial planners recommend a "Step-up SIP" — increasing your monthly contribution by 10 to 15% each year alongside salary increments. If you increase your ₹5,000 SIP by 10% each year for 20 years at 10% returns, your corpus is ₹1.23 crore vs ₹38.3 lakh from a flat ₹5,000 SIP. The step-up approach creates 3× more wealth on roughly the same lifestyle sacrifice.
Best savings options in India — with realistic return rates
Savings bank account (3–4% p.a.): Safe and liquid but returns below inflation. Use only for your emergency fund (3–6 months of expenses) that you need instant access to. Do not keep long-term savings here.
Fixed Deposit — FD (6.5–8% p.a.): Safe, guaranteed returns, available from 7 days to 10 years. Senior citizens get 0.25–0.5% extra. Good for short-term goals (1–5 years) where capital safety is priority. Interest is taxable as per your income slab. Use quarterly compounding setting in this calculator for FD projections.
Public Provident Fund — PPF (7.1% p.a., tax-free): Government-backed, 15-year lock-in, ₹1.5 lakh annual maximum. The 7.1% is effectively much higher after tax because the interest is completely tax-exempt under Section 10. Best for long-term, tax-efficient, guaranteed savings. Compounded annually — use annual compounding in this calculator.
National Savings Certificate — NSC (7.7% p.a.): Government scheme, 5-year tenure, interest compounded annually and added to principal (taxable but can claim 80C deduction on accrued interest). Minimum ₹1,000, no maximum. Use annual compounding in this calculator.
Equity Mutual Funds via SIP (10–14% p.a. historical average): Market-linked, so returns are not guaranteed, but over 10+ year horizons, large-cap equity funds have historically delivered 10–14% CAGR. ELSS (Equity Linked Savings Scheme) adds Section 80C tax benefit with 3-year lock-in. Use 10–12% in this calculator for conservative long-term projections; monthly compounding.
National Pension System — NPS (8–10% p.a. projected): Government-regulated pension fund, mandatory lock-in until age 60. Offers additional ₹50,000 deduction under Section 80CCD(1B) beyond the ₹1.5L 80C limit. At maturity, 40% must be used to purchase an annuity; 60% is tax-free. Use 9% with monthly compounding in this calculator for NPS projections.

Frequently asked questions
How does compound interest work in a savings calculator?
Compound interest means you earn interest not just on your original deposit (principal) but also on the interest that has already been added to your account. This creates a snowball effect — your balance grows faster each year because the base keeps increasing. For example: ₹1,00,000 at 8% simple interest for 10 years = ₹1,80,000. The same ₹1,00,000 at 8% compound interest (monthly) for 10 years = ₹2,22,039. That extra ₹42,039 is the compounding effect — and it becomes dramatically larger over 20–30 year horizons. The year-by-year chart in this calculator visually shows this acceleration — the gap between the blue total-value line and the green contributions line is your compound interest.
Can I use this to calculate SIP returns?
Yes — this is one of the primary use cases. Enter your monthly SIP amount in the "Monthly contribution" field, set your expected annual return rate (use 10–12% for equity mutual funds over long periods, 7–8% for balanced funds, 6.5–7.5% for FD/RD), choose Monthly compounding, and enter the investment duration in years. Set Initial Amount to ₹0 if you have no existing corpus. The calculator then shows your total corpus (Future Value), total amount invested, and total interest/returns earned. Note: mutual fund SIP returns are based on NAV fluctuations, not a fixed rate — so treat this as a projection, not a guarantee. Use 10% for a conservative equity SIP estimate and 12% for an optimistic scenario.
What compounding frequency should I use for different savings products?
Match the compounding frequency to your actual savings product for the most accurate estimate: Monthly — savings bank accounts, recurring deposits, and mutual fund SIPs; Quarterly — most bank Fixed Deposits (FDs) in India compound quarterly; Annually — PPF, NSC, and some small savings schemes compound annually; Daily — some high-yield savings accounts and liquid funds use daily compounding. If you are doing general long-term planning and are not sure, use Monthly as the default — it is the most common and gives results close to the actual for most products. The difference between monthly and daily compounding on most amounts is small, but the difference between annual and monthly compounding on long-term investments is significant.
How much do I need to save monthly to reach ₹1 crore?
It depends entirely on your return rate and time horizon. Here are reference figures at 10% annual return, monthly compounding: 10 years → ₹48,822/month; 15 years → ₹24,041/month; 20 years → ₹13,168/month; 25 years → ₹7,532/month; 30 years → ₹4,417/month. Notice how starting earlier dramatically reduces the required monthly amount — at 30 years you need less than 1/10th of what you'd need for a 10-year plan. For a higher return of 12% (aggressive equity), the 20-year figure drops to ₹10,109/month and the 30-year figure drops to ₹2,862/month. Use this calculator with your own starting amount to find your exact monthly target after accounting for existing savings.
What is the difference between FV (Future Value), Total Invested and Interest Earned?
Future Value (FV) is the total amount of money you will have at the end of the savings period — your starting amount, all your monthly contributions, and all compound interest added together. This is the final corpus number. Total Invested is how much money you personally put in — your initial deposit plus all your monthly contributions over the years. This is your out-of-pocket cost. Interest Earned = Future Value − Total Invested. This is the money the bank, fund, or scheme gave you as a return — it is the reward for saving and the measure of how hard your money worked for you. A well-structured long-term savings plan should have Interest Earned significantly exceed Total Invested. In the 30-year retirement example above (₹10,000/month at 10%), Total Invested = ₹36 lakh and Interest Earned = ₹1.9 crore — compound interest contributes over 5× more than the saver themselves.
Does this calculator account for inflation and taxes?
This calculator projects nominal future value — meaning it does not automatically adjust for inflation or tax deductions. To account for inflation informally, subtract the expected inflation rate from your return rate. For example, if you expect 10% returns and 6% inflation, use 4% as your "real return rate" to see inflation-adjusted growth. For taxes: FD interest is fully taxable at your income slab rate (20% for most working-age savers), which can reduce effective post-tax FD returns from 7.5% to ~6%. PPF and ELSS (after 3 years) are tax-exempt on returns — so their effective rate is higher than the nominal rate for tax-paying investors. For major financial decisions like retirement planning, always consult a SEBI-registered financial advisor who can run projections that account for inflation, taxation, and your full financial picture.
Is this savings calculator accurate for real financial planning?
This calculator uses the standard compound interest formula (A = P(1 + r/n)^nt) and the future value of annuity formula for monthly contributions — the same formulas used by financial institutions, AMFI SIP calculators, and banking software. Results are mathematically accurate for the inputs given. However, real-world savings have variable factors this calculator cannot model: mutual fund SIP returns fluctuate with market performance, FD interest rates change with RBI policy, PPF rates are reviewed quarterly by the government, and inflation erodes purchasing power. Use this calculator for goal-setting, scenario comparison, and understanding the power of compound interest — then refine your actual investment plan with a qualified financial advisor for binding decisions.
