Investment Calculators
Stock return, CAGR, dividends, lump-sum & SIP growth, and bonds. Free, no signup, runs in your browser.
Stock return
Total return on a buy/sell, including fees and any dividends received.
CAGR (Compound Annual Growth Rate)
The steady annual growth rate that would turn a starting value into an ending value over N years.
Dividend yield & income
What a holding pays you per year, before and after tax.
Lump sum vs. monthly (SIP) growth
Compare investing a lump sum today against contributing the same total gradually every month, at the same assumed return. Uses the same monthly-compounding convention as the site's main SIP calculator.
This compares two ways of investing money you already plan to invest — it isn't a claim that either beats the other; markets don't move in a straight line, and the "lump sum" side assumes you have that full amount available today.
Bond price, yield & duration
Standard bond math: price from a yield, yield from a price, and interest-rate sensitivity (duration).
Modified duration is roughly the % change in price for a 1-percentage-point change in yield (in the opposite direction). No accrued interest is included (clean price).
Frequently Asked Questions
Why don't these calculators show live prices?
They don't need to — they compute results from numbers you enter. For a dated reference price on gold, silver or US Treasury yields, see the gold, silver and bonds pages.
What SIP convention does the growth calculator use?
The same one as fin·calc's main SIP calculator: monthly contributions compounding as an annuity-due (each contribution is assumed to be made at the start of its month), matching the number you'd get from the homepage tool with the same inputs.
Is this investment advice?
No. These are calculators and reference tools only — fin·calc doesn't recommend any stock, fund, bond or timing decision, and isn't a licensed financial adviser.
