How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Use the result with context

Results are estimates for planning and education. Confirm rates, taxes, fees, and legal requirements with the relevant institution or a qualified professional before making a financial decision.

Formula and method

Four consecutive quarterly amounts of 100, 200, 300 and 400 sum to a trailing total of 1,000.

Trailing total = Q1 + Q2 + Q3 + Q4; P/E = share price / trailing EPS; EV/EBITDA = enterprise value / trailing EBITDA.

Worked example

Enter these known values and leave the other values blank.

Assumptions and limitations

  • Use four consecutive non-overlapping quarters, all under consistent accounting conventions. Fiscal quarters need not be calendar quarters.
  • Dividend mode divides aggregate dividends by the entered share count before calculating yield. Enter aggregate dividends rather than per-share dividends in that mode. Valuation denominators must be nonzero.
  • Enter all money amounts in one currency. The retained currency conversion menu uses captured historical conversion factors, not current exchange quotes.
  • Clear an unknown editable field before solving an inverse; fixed selections and output-only fields cannot be inferred.

Common questions

Use four consecutive non-overlapping quarters, all under consistent accounting conventions. Fiscal quarters need not be calendar quarters.
