Three levers to pull

  1. Monthly contribution — biggest effect over short-to-medium goals.
  2. Starting balance — biggest effect if you can route a lump sum from elsewhere.
  3. Interest rate — matters more over longer horizons.

What rate to use

Easy-access savings: 3-5%. Cash ISA: 3-5% (tax-free). Fixed-rate bond: 4-5%. Short-horizon goals (under 5 years) should use cash-level rates, not equity returns.

Common goals and realistic timelines

Frequently asked questions

What rate should I use for a 2-year house deposit?

A cash rate (3-5%), not an equity return. Equity exposure is inappropriate for sub-5-year goals due to volatility.

Does this account for tax?

No — the output is gross interest. Outside a Cash ISA and above your PSA, interest is taxed.
