Project what your ISA could be worth, see how much of the current UK allowance you are on track to use, and estimate the monthly amount needed to fully use it by the tax-year deadline.
Use the amount already paid into any cash ISA, stocks and shares ISA, innovative finance ISA or lifetime ISA this tax year.
Based on the current UK tax year. The annual ISA allowance is shared across all adult ISAs.
This is a planning estimate, not personalised financial advice. Actual investment returns, provider rules and subscription timing can change your result.
Allowance rule: The annual ISA limit is shared across your adult ISAs, so a cash ISA contribution reduces what is left for a stocks and shares ISA.
Lifetime ISA: If you use a LISA, its payments still count towards the wider annual ISA allowance.
Deadline: The UK tax year normally resets on 6 April. If you are close to the cap, check provider cut-off times for transfers and same-day top-ups.
