Description
Return cash total return and either final price plus cash dividend or final price×(1+dividend/reinvestmentPrice).
A simple return is a change relative to an initial value, while a gross return is a wealth multiplier and a log return uses a logarithm of that multiplier. Dividend, split, fee and currency conventions change what is included.
Return cash total return and either final price plus cash dividend or final price×(1+dividend/reinvestmentPrice).
When to use this tool

How to use the tool and how it works
- Enter initialPrice, finalExDividendPrice, dividend, reinvested, reinvestPrice. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read cashTotalReturn, finalWealth. Use the output convention below.
Require positive initial/reinvestment prices and nonnegative ex-dividend price/dividend. Return cash total return and either final price plus cash dividend or final price×(1+dividend/reinvestmentPrice).1

}Limitations and assumptions
- Final wealth is for one initial share; reinvestment price is required even when unused. Cash return is not recomputed as a reinvested return, and fees/taxes are absent.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
