THE BIG PICTURE
Final portfolio value
What portfolio value results from your assumptions? See how contributions, reinvestment and price development play their part.

DIVIENTAPlan your dividends
Explore how your portfolio and dividends could develop based on your assumptions. Plan contributions and reinvestment while keeping gross dividends, net dividends and taxes in view.
Scenario model – not investment advice
THE IDEA
DIVIENTA is a scenario calculator for long-term dividend planning. You define your starting point and choose how contributions, dividends, reinvestment, price development and taxes should evolve within the model.
The native app then calculates, year by year, what development would result from those assumptions. It does not analyse individual securities or use market data to make predictions.
Start with your current portfolio and contribution plan.
Define dividends, reinvestment, price development and tax model parameters.
See what your assumptions could mean for portfolio value, dividends and capital structure over time.
YOUR ASSUMPTIONS
Your portfolio is the starting point. Add your contribution plan and assumptions. Each factor is considered separately, then brought together in your scenario.

How many years do you want to model?
What is your portfolio worth today? Which contributions, reinvested dividends and capital gains are already included?
How much will you invest each year, and by what amount should that annual contribution increase?
What initial yield and dividend growth do you assume? What share of net dividends will you reinvest?
What long-term price development should the scenario assume?
What tax rate and available annual tax allowance should the model use?
THE RESULTS
Understand how dividends, taxes, reinvestment, contributions and price development interact.
THE BIG PICTURE

ONE PARTICULAR YEAR
Gross income, net income and taxes clearly separated. See how much is reinvested and what remains available to withdraw.
THE COMPONENTS
Your own contributions, reinvested dividends and capital gains or losses, including the amounts already in your starting portfolio.
THE SUM OF THE YEARS
All modelled dividends and taxes, total reinvestment and withdrawals across the forecast years.
A CONCRETE EXAMPLE
One starting portfolio. Ten years. Clearly defined assumptions. Here is how development could look within this model.
The starting point
10 years2027–2036
Previously reinvested dividends and existing capital gains are included in the starting portfolio.

Scenario model – not investment advice
Net dividend yield is based on portfolio value before reinvestment at the end of the year.
Net dividend in the final year divided by twelve. Actual monthly distributions may vary. With 100% reinvestment, nothing is withdrawn in this example.

The values shown result solely from the assumptions listed above. They are not a prediction of actual market developments or future returns. Values are rounded independently to two decimal places. Rounding differences may occur.
YEAR BY YEAR
Follow the development over time. In the app, open an individual year to understand how contributions, dividends, taxes and reinvestment work together.
Your own annual contribution plus dividends reinvested during the year make up the total annual investment.
Cumulative own contributions, invested capital including reinvestment and portfolio value remain clearly distinguishable.

KEEP YOUR SCENARIOS
Save your assumptions as individual scenarios and return to them later. Scenarios can be loaded, renamed and updated.
Your data stays on your device.
PRIVATE BY DESIGN
DIVIENTA does not require an account or a cloud service. Your scenarios are stored locally on your iPhone or iPad.
Use the app without creating a user account.
You do not need an internet connection to calculate your scenarios.
Your saved scenarios remain on your device.

This website takes the same restrained approach: no tracking, cookies or external fonts.
Read the website privacy noticeHOW DIVIENTA CALCULATES
DIVIENTA calculates in annual steps. Your contribution is invested at the beginning of each forecast year. The model price and dividend per model unit develop according to your assumptions. Modelled taxes are deducted from the gross dividend, and the selected share of net dividends is reinvested at the end of the year.
Add contribution

Update price and dividend
Calculate gross dividend
Model taxes
Calculate net dividend
Reinvest the selected share

Model units purchased from reinvested dividends begin generating dividends from the following forecast year.
CURRENT STATUS
The app is currently in development. This website offers a look at its concept, features and calculation model. Actual app screenshots will be added once the interface is sufficiently finalised.
