SIP and lumpsum calculators for mutual fund planning

A SIP calculator shows how small monthly investments compound over time. Enter your monthly amount, expected annual return and duration to see invested amount, estimated returns and maturity value. If you have a large amount to invest at once, the lumpsum calculator shows how a one-time investment can grow. Remember that mutual fund returns are market-linked and not guaranteed.

Loan EMI calculator for personal, home and car loans

Before you borrow, check your monthly instalment with our loan EMI calculator. It uses the reducing-balance method and shows total interest and the full repayment schedule. A small change in interest rate or tenure can change your total cost by a large amount, so compare a few options first.

Credit card payoff, crypto tax and freelance rates

The credit card payoff calculator shows how long clearing your balance will take at different monthly payments. The crypto tax calculator helps estimate tax on virtual digital asset gains under Indian rules. Freelancers can use the freelance rate calculator to turn annual income goals and expenses into an hourly rate.

Compare demat accounts and loan apps

Choosing a platform matters as much as choosing an investment. Our best fintech apps comparison covers demat account charges, brokerage and personal loan app fees. Read our review methodology to see how we evaluate and how affiliate links are disclosed.

Frequently Asked Questions

TechFin Review is a free website with financial calculators for SIP, lumpsum, loan EMI, credit card payoff, crypto tax and freelance rates, plus comparisons of demat and loan apps.
Yes. All calculators are free to use, with no signup or subscription.
Calculations run in your browser, and the figures you enter are not sent to our servers. No login is needed.
We use the future value of an annuity-due formula: M = P × ([(1 + i)^n − 1] / i) × (1 + i), where P is the monthly investment, i is the monthly rate and n is the number of months. Actual returns vary with the market.
EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the loan amount, r is the monthly interest rate and n is the tenure in months. Your lender’s final EMI may differ slightly due to fees and rounding.
Gains from virtual digital assets are generally taxed at a flat 30% plus cess, with 1% TDS on transfers, and losses cannot be set off against other income. Tax rules change, so verify with the Income Tax Department or a chartered accountant.
Add your target annual income, business expenses and taxes, then divide by the hours you can realistically bill. Our freelance rate calculator does this for you.
No. Our tools and articles are for education only and are not investment, tax or legal advice. Please consult a qualified professional before making decisions.
