Whether you are planning your first SIP, calculating whether a bank FD beats inflation, working out your home loan affordability, or deciding whether to stay on the Old Tax Regime for HRA benefits — these calculators give you precise answers with the correct Indian tax and financial rules applied.
TDS thresholds, DICGC limits, HRA section 10(13A), Old vs New regime — all built in.
Standard reducing balance EMI, compound SIP, and Section 10(13A) HRA formulas used by Indian banks and tax authorities.

Calculate the maturity value of a Systematic Investment Plan (SIP) over any period at any expected annual return rate. The step-up feature lets you model increasing contributions — for example, raising your SIP by 10% every year in line with salary increments. The tool shows a year-by-year growth chart, total invested amount, total returns, and final corpus. Also supports goal-based reverse calculation: enter your target amount to find the required monthly SIP.
Formula: M = P × ((1 + r)^n − 1) / r × (1 + r), where r = monthly rate, n = months
Calculate Fixed Deposit maturity amount, interest earned, and post-TDS payout for any bank FD. Supports quarterly, half-yearly, and annual compounding. Accounts for the senior citizen rate benefit (+0.50%) and TDS deduction at ₹40,000 threshold (₹50,000 for seniors). Shows year-by-year interest accrual and breakup of principal vs interest. DICGC insurance coverage note: up to ₹5 lakh per depositor per bank.
TDS: 10% with PAN / 20% without PAN above ₹40,000 interest per year (₹50,000 for senior citizens)
Calculate the monthly EMI for any loan using the reducing balance method. Enter loan amount, interest rate, and tenure to get the monthly instalment, total interest paid, and total repayment amount. Supports prepayment planning to see how lump-sum payments reduce total interest and loan tenure. Also includes a FOIR (Fixed Obligation to Income Ratio) affordability check and side-by-side loan comparison.
Formula: EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where r = monthly interest rate
Calculate your HRA tax exemption under Section 10(13A) of the Income Tax Act. Computes all three conditions: actual HRA received, actual rent minus 10% of basic salary, and 50%/40% of basic for metro/non-metro cities. Shows which condition gives the minimum (which becomes your exemption). Compares Old vs New Tax Regime to help you decide which results in lower total tax. Also calculates the minimum rent required to claim maximum HRA exemption.
HRA exemption = min(HRA received, rent paid − 10% basic, 50%/40% basic for metro/non-metro)
Calculate compound interest growth for any initial investment over any period at any rate, with daily, monthly, quarterly, half-yearly, or annual compounding. Shows total interest earned, effective annual rate (EAR), CAGR, and a year-by-year growth chart. Includes inflation-adjusted real returns so you can see the actual purchasing power gain. Compare with simple interest to see the compounding advantage.
Formula: A = P × (1 + r/n)^(nt), where n = compounding frequency per year
| Feature | SIP (Mutual Fund) | FD (Bank) | Compound Interest |
|---|---|---|---|
| Returns | 10–14% p.a. (variable) | 6.5–7.5% p.a. (fixed) | Depends on instrument |
| Risk | Market risk | Zero risk | Depends on instrument |
| DICGC Insurance | Not applicable | Up to ₹5 lakh | Not applicable |
| Tax on Returns | LTCG 12.5% (>₹1.25L) | Interest taxed as income | Depends on instrument |
| Minimum Investment | ₹500/month | ₹1,000 (varies by bank) | Any amount |
| Liquidity | T+3 redemption | Penalty on premature withdrawal | Depends |

The SIP calculator uses the standard compound interest formula for mutual fund SIP returns: M = P × ((1 + r/n)^nt − 1) / (r/n) × (1 + r/n). It assumes a fixed annualised return rate and monthly compounding, which is the industry standard for SIP projections. Actual returns vary based on fund performance — the calculator provides an estimate based on the rate you enter.
Step-up SIP (also called top-up SIP) means increasing your monthly SIP amount by a fixed percentage every year — for example, increasing from ₹5,000/month by 10% each year. This aligns with typical annual salary increments. The DDaverse SIP calculator has a step-up option where you enter the annual increase percentage to see the impact on total corpus.
Yes. The FD calculator includes TDS deduction based on the ₹40,000 threshold (₹50,000 for senior citizens as per current rules). It also accounts for the senior citizen rate benefit (+0.50% at most banks) and shows year-by-year interest growth. TDS is calculated at 10% if PAN is provided, or 20% without PAN.
HRA exemption under Section 10(13A) of the Income Tax Act is the minimum of three values: (1) actual HRA received from employer, (2) actual rent paid minus 10% of basic salary, and (3) 50% of basic salary for metro cities (Mumbai, Delhi, Chennai, Kolkata) or 40% for non-metro cities. The DDaverse HRA calculator computes all three conditions and shows the exempt amount.
HRA exemption is only available under the Old Tax Regime. Under the New Tax Regime (introduced in Budget 2020 and made default from FY 2023-24), HRA exemption cannot be claimed. The DDaverse HRA calculator shows the tax comparison between both regimes so you can decide which regime results in lower tax.
The EMI calculator uses the standard reducing balance formula: EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the principal loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the total number of monthly instalments. This is the formula used by all Indian banks for home loans, car loans, and personal loans.
CAGR (Compound Annual Growth Rate) is the annualised return rate that would take an investment from its starting value to its ending value over a period of years, assuming annual compounding. The compound interest calculator shows CAGR alongside the total return, so you can compare investments made over different time periods on an equal basis.
Use the DDaverse SIP calculator in reverse (goal-based) mode. Enter your target corpus (₹1 crore), expected return rate (typically 12% for equity mutual funds), and investment duration. The calculator will show the required monthly SIP amount. For example, to reach ₹1 crore in 20 years at 12% annual return, you need approximately ₹10,000/month.
Simple interest is calculated only on the principal amount. Compound interest is calculated on the principal plus the accumulated interest, so interest earns interest over time. For investments, compound interest grows wealth significantly faster over long periods — this is why Warren Buffett calls it the eighth wonder of the world. The DDaverse compound interest calculator shows both values side by side.
SIP in equity mutual funds typically offers higher long-term returns (10–14% p.a. historically) but comes with market risk. FD offers guaranteed returns (currently 6.5–7.5% p.a. at major banks) with zero risk, protected up to ₹5 lakh per depositor per bank by DICGC insurance. The right choice depends on your risk appetite, time horizon, and tax situation. Use both calculators to compare the projected corpus.
