It is important to understand that the calculator only gives an estimate. Many factors are unknown and assumptions have been made. It is designed to show how making a few small changes can make a difference to your retirement. It does not provide a pension illustration.

The calculator doesn’t consider the current Lump Sum Allowance (LSA), or Lump Sum and Death Benefit Allowance (LSDBA) or any restrictions on tax free cash that can be taken from a pension.

We provide a pension illustration when you apply to open a SIPP account. We provide further illustrations annually and at other important times, such as when benefits are accessed. These are based on individual circumstances and the rules and assumptions set out by the Financial Conduct Authority.

How our SIPP can help you meet your retirement goals

A SIPP (Self Invested Personal Pension) puts you in control of your retirement planning. You get to choose how and where your pension is invested, with a range of flexible drawdown options available at retirement.

  • With ii, you will have access to more investment options than any other provider in the market. We have a choice of over 40,000 UK, US and international shares, funds, trusts, ETFs, bonds and gilts, and VCTs.
  • Or if you’re not sure where to start, our Quick Start Funds can get you up and running.
  • Our low, flat fees could give you thousands more in retirement. Most other providers charge percentage fees that grow with your pension value.
  • We don’t charge for regular investments into your SIPP – many other providers do. 
  • Our SIPP gives you flexibility over contributions. You can top it up with regular personal and employer contributions, or simply make one-off payments. The choice is yours.
  • Simplify your pensions: consolidating old pensions into one SIPP can make it much easier to keep track.
  • Our SIPP is Which? Recommended.

Which? Recommended SIPP

Please remember, SIPPs are aimed at people happy to make their own investment decisions. Investment value can go up or down and you could get back less than you invest. You can normally only access the money from age 55 (57 from 2028). We recommend seeking advice from a suitably qualified financial advisor before making any decisions. Pension and tax rules depend on your circumstances and may change in future.
