Example Data
Use this sample to understand inputs and outputs.
| Input | Example |
|---|---|
| Lump Sum Amount | ₹ 10,000 |
| Annual Return | 10% |
| Period | 8 years |
| Compounding | Monthly |

Formula Used
Future value with compounding: FV = P × (1 + r/m)m×t
- P is invested amount after upfront fee.
- r is annual return, m is compounds per year, t is years.
- Annual fee is deducted from year-end balance (prorated for fractional years).
- Tax: max(FV − P, 0) × taxRate, applied at the end.
- Real value: Value ÷ (1 + inflation)t.

Lump Sum Growth Mechanics
For a single deposit, growth is driven by time and the effective periodic rate. If you invest ₹100,000 at 10% for 10 years, simple annual compounding yields about ₹259,374 before fees and taxes, assuming constant returns. Small changes in rate can dominate results more than small changes in timing.
Impact of Compounding Frequency
More frequent compounding slightly increases future value when the annual rate is the same. At 10% for 10 years, annual compounding gives 2.5937× the principal, while monthly compounding gives roughly 2.7070×, a difference of about 4.4% on the ending balance.
Fees and Drag on Returns
Annual management fees reduce the base that compounds next year. A 0.50% yearly fee on a ₹250,000 balance is ₹1,250, and that missing amount no longer earns returns. Over long horizons, even small fees can reduce net outcomes by several percent. An upfront fee works immediately: a 2% upfront fee on ₹100,000 invests only ₹98,000, so the entire growth curve starts from a lower base.
Taxes on Capital Gains
This calculator applies tax to total gains at the end of the period, which mirrors many simplified planning models. If your invested amount is ₹100,000 and the ending value is ₹260,000, the gain is ₹160,000. At 10% tax, the tax bill is ₹16,000. If the tax rate is 20%, the same gain reduces your ending value by ₹32,000.
Inflation and Real Wealth
Nominal money grows, but purchasing power depends on inflation. With 4% inflation, ₹200,000 in 10 years is worth about ₹135,000 in today’s terms. The inflation-adjusted net value helps compare goals like education funding or retirement spending. When inflation is higher than expected, “real” progress can stall even if the nominal balance rises.
Using the Yearly Schedule
The schedule shows start balance, investment gain, fee impact, and the inflation-adjusted end for each year. Use it to spot when compounding accelerates, quantify fee drag, and export results for discussion with a planner or for tracking progress against your target. A practical review step is to compare the last two years’ gains, because increasing gains often indicate compounding is doing the heavy lifting.
FAQs
1) What return should I use?
Use a realistic long-term estimate based on your asset mix. Many planners model multiple scenarios, such as conservative, base, and optimistic returns, to understand the range of outcomes.
2) Why do fees matter so much?
Fees reduce your balance every year, and that reduced balance compounds forward. Over long periods, a small annual fee can create a noticeable gap versus a no-fee projection.
3) How is tax calculated here?
Tax is applied to total gains at the end: max(FV − invested, 0) × tax rate. This is a planning simplification and may differ from your local rules or yearly taxation.
4) What does inflation-adjusted mean?
It converts future money into today’s purchasing power by discounting with inflation over time. It is useful for goal planning because expenses also rise with inflation.
5) Can I model daily compounding?
Yes. Select “Daily” under compounding. The difference versus monthly is usually small at typical rates, but it can matter for higher rates or longer horizons.
6) Is this a guarantee of performance?
No. The calculator is an estimation tool. Real markets vary, and fees, taxes, and returns can change. Use it for planning scenarios, not as a promise of results.
