Uses the compound interest formula A = P(1 + r/n)^(nt) — or A = Pe^(rt) for continuous compounding — with monthly contributions distributed across periods. Investment returns vary; this is a deterministic projection, not a guarantee.

टूल परिचय

Project how a starting amount and optional monthly contributions grow over time under compound interest. Choose the compounding frequency — from daily to continuous — and see the year-by-year balance, total contributions, and interest earned.

टूल अवलोकन

Compound interest is interest that earns interest: each period, the balance is multiplied by 1 + r/n (or e^(r/n) in the continuous limit), so growth is exponential rather than linear. This calculator treats principal plus optional regular contributions the same way a savings account, fixed deposit, SIP, or index-fund projection would. Results are deterministic — real investment returns fluctuate — so treat the output as a planning estimate, not a guarantee.

उपयोग के मामले

  • Plan a retirement, emergency-fund, or down-payment target
  • Compare a lump-sum investment to a systematic monthly plan
  • Estimate future value of a fixed deposit or index fund
  • Quantify how compounding frequency changes the final balance

अक्सर पूछे जाने वाले प्रश्न

What is the compound interest formula?+
A = P · (1 + r/n)^(n·t), where P is principal, r is the annual rate, n is the number of compounding periods per year, and t is time in years. For continuous compounding the formula is A = P · e^(r·t).
How are monthly contributions handled?+
Contributions are converted to a per-period amount (for example, $500/month becomes $1,500/quarter when compounding is quarterly) and added at the end of each period before the next compounding step.
Is this a SIP (Systematic Investment Plan) calculator?+
Yes — use the monthly-contribution field and pick monthly compounding to model a typical SIP at an assumed annualized return.
Does compounding frequency matter much?+
At typical savings rates the difference between daily and continuous compounding is small, but over long horizons or higher rates it is noticeable. Try the same inputs across frequencies to see the gap.
