日本新 NISA 試算
Project how your money could grow in Japan's New NISA (started 2024). Enter a monthly contribution, an assumed annual return and a number of years to see the future value — plus how much tax you save, since NISA gains are tax-free while a regular account is taxed at about 20.315%.
以固定報酬率估算，並非投資建議。實際結果會有變動。新 NISA：每年 360 萬日圓、終身 1,800 萬日圓，收益免稅。
常見問題
What is the New NISA?+
It is Japan's tax-free investment account, renewed in 2024. It has an accumulation frame (¥1.2M/year) and a growth frame (¥2.4M/year) — up to ¥3.6M per year and ¥18M over your lifetime — and investment gains stay tax-free indefinitely.
How is the tax benefit calculated?+
A regular taxable account in Japan is taxed about 20.315% on investment gains. This simulator shows that tax — which the New NISA lets you keep — as the tax-free benefit.
Is this investment advice?+
No. It is an estimate based on a constant assumed return and is not investment advice. Real returns vary; make your own decisions.
