Which tax regime saves more for ₹15 lakh salary?
Comparisons
Side-by-Side Comparisons
See how different options stack up, before you decide.
Choosing between two financial products is easier when you see them side by side. Each comparison highlights the key differences in returns, risk, tax treatment, and suitability so you can make an informed decision based on your own financial situation.
Should you invest a lump sum today or spread it across twelve monthly SIPs? Is the new tax regime better than the old one for your salary bracket? Does a fixed deposit still make sense when debt mutual funds offer indexation benefits? These are real questions that every Indian investor faces, and the answer depends on your income, goals, and risk tolerance. Our comparison guides walk you through each scenario with real numbers, tables, and calculator links so you can see the difference for yourself.
SIP vs Lumpsum
Spread entry vs all-at-once. SIP reduces timing risk.
New Tax Regime vs Old Tax Regime
Lower rates with fewer deductions vs higher rates with 80C, HRA.
FD vs Debt Funds
Guaranteed returns vs market-linked, both taxed at slab rate.
Flat SIP vs Step-Up SIP
Fixed vs annually increasing. Step-up can double your corpus.
NPS vs PPF
Market-linked pension vs sovereign-guaranteed savings.
Buy vs Rent
Ownership vs flexibility. Buy builds equity.

SIP
A Systematic Investment Plan (SIP) is a way to invest a fixed amount in a mutual fund at regular intervals, usually monthly, instead of a lump sum.
Mutual Fund
A mutual fund pools money from many investors and a professional manager invests it across stocks, bonds or other assets on their behalf.

The Public Provident Fund (PPF) is a government-backed savings scheme with a 15-year lock-in, tax-free interest and Section 80C tax deductions.
NPS

EPF
The Employees' Provident Fund (EPF) is a retirement scheme where you and your employer each contribute 12% of your basic salary every month.

Net Asset Value (NAV) is the per-unit price of a mutual fund: its total assets minus liabilities, divided by the number of units outstanding.
ETF
An Exchange-Traded Fund (ETF) is a basket of securities, often tracking an index, that trades on a stock exchange like a single share at low cost.
