Return on investment31.82%

ROI compares net gain or loss with all entered costs. It includes the final value and income received, and represents the whole investment outcome rather than an annual return.

Method

Total cost C = initial cost + additional costs. Net gain G = final value + income − C. ROI = (G/C) × 100%, with C greater than zero.

How this calculation works

Measure total profit or loss against all costs you enter, including additional acquisition or project costs. Income received during ownership is added to the final value. This is a whole-period return: it cannot distinguish earning the same profit in one year from earning it in ten.

Total cost C = initial cost + additional costs. Net gain G = final value + income − C. ROI = (G/C) × 100%, with C greater than zero.

Worked example

This example uses illustrative inputs. Your current result is shown above.

An asset costs ₹1,00,000 plus ₹10,000 in additional costs, finishes worth ₹1,40,000 and pays ₹5,000 income. Total cost is ₹1,10,000; gain is ₹35,000; ROI = ₹35,000 ÷ ₹1,10,000 × 100 = 31.82%.

Assumptions and limits

  • All entered costs and receipts belong to the same investment.
  • Income is counted once and is not automatically reinvested.
  • There is no timing, annualisation or tax adjustment beyond costs you explicitly enter.

Questions people ask

Should dividends or rent go in final value?

Put cash income already received in the income field and the ending sale or market value in final value. Do not include the same receipts in both.

Should I compare investments with different holding periods using ROI?

Whole-period ROI alone hides the time taken. CAGR can compare an uninterrupted starting and ending balance; XIRR is better suited to several dated deposits or withdrawals.
