How the calculation works

Each annual contribution is treated as a separate fixed-term investment. Interest accrues on a simple basis during the term. At maturity, tax is applied to the interest only. The net maturity proceeds are then reinvested, allowing one term's return to become part of the capital base for the next.

Your capital is at risk. You may lose all the money you invest. Returns are not guaranteed and past performance is not a reliable indicator of future results. This calculator is for illustrative and educational purposes only and does not constitute financial, investment or tax advice. It does not represent a projection of actual returns. Tax treatment depends on individual circumstances and may be subject to change. The calculation assumes the stated rate, term, tax treatment and immediate reinvestment remain unchanged throughout the selected period. If you are in any doubt as to whether an investment is appropriate for you, seek independent financial advice from a person authorised by the Financial Conduct Authority.
