Recommendation: use this page as the public calculator and as a smarter bridge into the signed-in portal.

For visitors, it works from manual inputs. For signed-in users, it can prefill from Tsang Portal data that already exists: base currency, monthly expenses target, financial freedom multiple, recent income and expenses, cash balances, and investment records. Missing assumptions such as age, retirement age, pension income, passive income and volatility remain explicit, because they are personal planning choices rather than ledger facts.

This is still planning information, not regulated financial advice. The best use is comparing scenarios and seeing which variables move the result most.

Turn the estimate into a tracked plan.

Tsang Portal can keep your net worth and goal progress current from your own ledger, without bank linking.
