The Method
How We Calculate Compound Growth
Future Value with Regular Contributions
FV = P × (1+r)^n + PMT × [((1+r)^n − 1) ÷ r]
P = initial deposit, PMT = monthly contribution,
r = monthly interest rate, n = number of months
Worked Example
Step-by-Step Example
₹50,000 initial deposit, ₹5,000/month, 7% annual interest, over 10 years.
Monthly rate: 7% ÷ 12 = 0.583% per month
Number of months: 10 years × 12 = 120 months
Initial deposit grows to: ₹50,000 × (1.00583)^120 ≈ ₹99,900
Contributions grow to: ₹5,000/month compounding ≈ ₹8,64,000
Total future value: ≈ ₹9,63,900 (₹6,50,000 contributed + ₹3,13,900 interest earned)
Quick Reference
Rule of 72: How Fast Your Money Doubles
A quick mental-math trick — divide 72 by your interest rate to estimate how many years it takes your money to double (with no further contributions).
| Interest Rate | Years to Double |
|---|---|
| 4% | 18 years |
| 6% | 12 years |
| 7% | ~10.3 years |
| 8% | 9 years |
| 10% | 7.2 years |
| 12% | 6 years |

Tips for Growing Your Savings Faster
Start Early
Time in the market matters more than timing — an extra 5 years of compounding often outweighs a higher contribution started later.
Automate Contributions
Setting up automatic monthly transfers removes the temptation to skip a month.
Increase Contributions with Raises
Bump your monthly savings amount every time your income increases, even by a small percentage.
Compare Compounding Frequency
More frequent compounding (monthly vs annual) slightly increases your effective return over time.
Review Your Progress
Check your savings plan every few months and adjust contributions if your goals or income change.
Avoid Unnecessary Withdrawals
Keeping your savings invested allows compound growth to work without interruption.

Saving in India: what to know
The calculator works for any savings plan. A few points matter specifically for savers in India:
- Fixed deposits: most Indian banks compound FD interest quarterly. This calculator compounds monthly, so for the same rate its result can be slightly higher than your bank's FD maturity amount.
- Deposit insurance: DICGC insures bank deposits up to ₹5 lakh per depositor, per bank, covering principal and interest together.
- Small savings schemes: the government revises PPF and other small savings rates every quarter. Check the current rate before you plan.
- Tax: FD and RD interest is taxable at your income tax slab, and banks may deduct TDS. Your post-tax return is lower than the rate on the deposit.

Questions
Frequently Asked Questions
Compound interest is interest calculated on both your original deposit and the interest it has already earned, which causes your balance to grow faster over time compared to simple interest.
A fixed deposit calculator typically assumes a single lump sum with no further contributions. This calculator supports both a lump sum and ongoing monthly contributions, which better reflects how most people actually save.
Use the actual annual interest rate offered by your savings account, fixed deposit, or investment. For a general estimate, many savings accounts in India offer 3-7%, while long-term diversified investments have historically averaged higher, with more risk.
No, this calculator shows gross growth before tax. Interest income is typically taxable depending on your jurisdiction and account type — factor this in separately for a post-tax estimate.
A quick estimation trick: divide 72 by your annual interest rate to approximate how many years it takes a lump sum to double, assuming no further contributions.
It works backwards from your target amount, initial deposit, interest rate, and time frame to solve for the exact monthly contribution needed to reach your goal.
Generally yes for growth, but higher returns usually come with higher risk. Guaranteed savings products offer lower but more predictable rates than market-linked investments.
This calculator assumes consistent monthly contributions. Missing a month in real life will result in a slightly lower final balance than projected — the impact is usually small if it's occasional.
It assumes monthly compounding, which aligns with monthly contributions and is common for savings accounts and recurring deposit products.
Yes, it works well for long-term projections, though for detailed retirement planning you should also account for inflation, changing contribution amounts, and withdrawal strategy.
No, results are shown in nominal (today's) currency value. Inflation will reduce the real purchasing power of your future balance — for long time horizons, consider this separately.
Simple interest is calculated only on the original principal. Compound interest is calculated on the principal plus previously earned interest, so your growth accelerates over time.
Yes — with 0% interest, the calculator simply totals your initial deposit plus all contributions, with no growth added.
Compound interest grows exponentially, not linearly — money invested early has more compounding periods to grow, often outperforming larger contributions started later.
It can give a rough estimate using an assumed average annual return, but stock market returns fluctuate year to year and aren't guaranteed like fixed savings rates — treat results as an approximation, not a promise.
It's mathematically precise based on your inputs, assuming consistent monthly contributions and a constant interest rate throughout — real-world rates and contributions may vary.
Yes — use "Reach a Goal" mode with your target tuition amount and the number of years until you'll need the funds to see the required monthly savings.
No. All calculations run entirely in your browser — nothing you enter is sent to or stored on our servers.
No. It's a mathematical projection tool only. For personalised financial planning, consult a licensed financial advisor.
