Withdrawal cash-flow simulator
Separate principal, realized gain, estimated tax and spendable cash—year by year
Last updated: Built by the IndepAI team
Estimate gross and spendable cash flow
A deterministic projection disposes aggregate basis proportionally. Unknown basis keeps the portfolio path visible but withholds gain, tax and net-cash figures.
After inflation, before tax. This deterministic path does not model sequence risk.
Enter your own assumption. This is not a verified country, treaty or account rule.
Planning estimate · Limited
Cost basis is applied proportionally, but the tax rate is your illustrative assumption. Verify residency, treaty, account treatment and pension tax before relying on net cash.

Why withdrawal is not the same as taxable gain
A sale normally contains returned principal and gain. Treating every euro withdrawn as gain can materially overstate tax, while treating unknown basis as zero tax can materially understate it.
This tool disposes a known aggregate cost basis proportionally. When basis is unknown, it continues the gross portfolio projection and marks gain, tax and net cash as unavailable.
The rate is your explicit illustration, not a verified personal tax rule. Residence, treaty, account wrapper, losses, exemptions, wealth taxes and pension treatment require professional review.

Frequently Asked Questions
Why does cost basis matter?
Cost basis represents invested principal. A sale can return both principal and gain, so tax should not automatically apply to the full cash withdrawal.
What happens when my basis is unknown?
The gross withdrawal and ending-balance path remain available, but realized gain, estimated tax and net cash are withheld rather than guessed.
Is the lowest modeled-tax sequence tax advice?
No. It is an educational comparison under your own flat-rate and access assumptions. It does not prove residence, treaty, wrapper or filing treatment.
Does this model sequence risk and inflation?
Cash-flow mode accepts a constant real-return assumption. Optimization mode compares withdrawals without market returns. Neither measures sequence-risk failure probability.
Where this data comes from
City cost estimates are AI-modeled from curated price anchors and cross-checked against World Bank price-level data. Refreshed daily (incremental) and re-modeled in full every two months. Tax figures are modeled per country and currently being verified country-by-country against primary sources.
