Frequently Asked Questions

Crawlable FAQ content for humans and AI agents. See how the simulation logic works before installing.

What does the simulation do each year?

It computes yearly inflows, outflows, and asset growth. If outflows are higher than inflows, the app performs drawdown based on your configured order.

How does Drawdown Order work?

Drawdown order defines which source is used first when money is needed (for example: cash, savings, investments, tradeable assets). If one source is not enough, the next source is used automatically.

When are taxes applied?

Taxes are applied only on sell events (drawdown or forced liquidation), not on unrealized gains. Taxes are off by default until you configure and enable them.

What is the difference between tax treatments?

Standard uses a global tax rate on gains only. Tax-Free has no tax on sale. Custom uses a custom rate on gains only. Tax-Deferred taxes the full withdrawn amount, not just gains.

What is Cost Basis (optional)?

Cost basis is the amount originally paid for an asset. It helps estimate the gains portion on sale. Tradeable assets let you set a custom cost basis; if not provided, the app defaults to the asset value at creation time.

Are savings withdrawals taxed?

In most countries, interest on savings is taxed when your bank credits interest, not when you withdraw. The savings growth rate you enter should already be net of any interest tax.
