Yield on cost is an important metric for dividend investors because it represents the return on their initial investment in a particular holding.
It allows investors to track how their dividend income has increased or decreased over time, and helps them evaluate the performance of their portfolio over the long term.
​
​Since the update 2.35.0 we show the YoC for your portfolio!

To calculate the yield on costs for portfolio, we use the following formula:

Yield on Costs = (Total Dividends Paid in the last 12 Months) / (Total Cost Basis of Portfolio)

Total Cost Basis = Sum of average Buy ins + Transactions costs + paid taxes for buys

Example:

Your investment is 1000€ (997€ invested for stocks + 2€ transaction cost + 1€ buy taxes)

You got 100€ dividends in the 12 months.

Yield on Costs = 100€ divided by 1000€ = 0.1 or 1%
