Premium Bonds vs Savings Accounts
Premium Bonds offer tax-free prizes, but an individual return is uncertain and can be zero. A savings account pays interest under its stated terms. Compare the same amount and period, a current provider rate, access needs, tax position and your need for certainty. This page provides general information and scenarios, not a product ranking or personal recommendation.
How they differ
| Situation | Next step |
|---|---|
| Premium Bonds | Capital is backed by HM Treasury, while prizes are random and individual returns can be zero. |
| Savings account | Interest follows the account terms; access, tax and protection depend on the product and your circumstances. Check the provider and FSCS position for the specific account. |
Expected return is not a savings rate
The Premium Bonds prize-fund rate describes the whole prize fund, not the return each holder receives. Expected value is a long-run average across many possible outcomes. The median outcome can be lower, and an individual may win nothing during the period. A savings account’s stated AER follows its terms rather than a prize draw.
Build a like-for-like scenario
- Use the same starting balance and the same start and end dates.
- For savings, record the current AER, whether it is fixed or variable, when interest compounds, and any withdrawal restrictions.
- For Premium Bonds, use the calculator’s dated odds and prize-fund assumptions, then consider both no-prize and higher-prize outcomes rather than only the average.
- Compare the end balance, access conditions, tax treatment and your need for certainty.
Tax scenarios to check
| Situation | Next step |
|---|---|
| Interest within your available allowance | Savings interest may be covered by your Personal Savings Allowance, depending on your tax position and other interest. |
| Interest above your available allowance | Tax can reduce the net savings return. Use current GOV.UK rules or professional advice for your own calculation. |
| Tax-free account or prizes | Premium Bonds prizes are tax-free. Some savings wrappers may also be tax-free but have separate eligibility and contribution rules. |
