Frequently asked questions

This tool gives you an idea of the return you could earn over the lifetime of a gilt, assuming you hold it to maturity. 

Here’s how to use the Gilts return calculator: 

  1. Select the gilt you’re considering investing in from the dropdown list. 
  2. Enter the current market price. You check this in your Freetrade app or by clicking 'Check live price'. 
  3. Enter the amount of cash you’re thinking of investing in the gilt. 

The calculator will show you the total estimated return you could get if you bought the gilt at the inputted price and held it to maturity. 

It’ll also show you: 

  • How much of this estimated return will come from coupons
  • How much of this estimated return will come from the gain or loss realised at maturity
  • The running yield
  • The yield-to-maturity

Gilts are government bonds. 

When you buy a gilt, you’re lending money to the UK government. When the gilt matures, the government repays you the face value, or nominal value, of the gilt. 

Throughout the life of the gilt, the government also pays you coupons. These are regular dividends paid out every six months at a pre-determined rate. 

Let’s say you hold £1,000 nominal of £TR28 - 6% Gilt 2028. It matures on 7th December 2028, and offers an annual dividend rate of 6%. 

You’d receive £30 every six months until December 2028, at which point the government would pay you one final dividend of £30, as well as repaying you the £1,000 principal. 

Gilts are not subject to Stamp Duty Reserve Tax (SDRT) or capital gains tax. 

The coupons, however, are subject to income tax. Unless, of course, you hold them in an ISA or SIPP. Then you won’t pay any tax on the dividends. 

As a Freetrade Standard or Plus customer, you can buy gilts in your ISA, pension, or general investment account. 

Also known as the coupon, this is the fixed annual interest rate paid to gilt holders, expressed as a percentage of the gilt’s face value. The rate is quoted annually, but paid semi-annually. 

The annual dividend divided by the current market price of the gilt.

The annual return you'll receive if you buy a gilt at the current market price and hold it o maturity. As gilt prices rise, yields fall, and vice versa.

Important information

With gilts, market prices fluctuate. Your return will vary depending on the timing of your trades and market interest rates.

ISA and SIPP rules apply. Tax treatment depends on your personal circumstances and current rules may change.

A SIPP is a pension designed for people who want to make their own investment decisions. You can normally only access your money from age 55 (57 from 2028).

Freetrade currently only supports Uncrystallised Fund Pension Lump Sums (UFPLS) for SIPP withdrawals.

Seek professional advice if you need help with your pension.

How this SIPP calculator works

About this calculator

This calculator estimates how your pension pot may grow based on the information you enter, including your current pot, monthly contributions, investment period, assumed annual growth rate, and fees. It shows two projections: one for Freetrade and one for your selected provider, or Others if you enter custom fees.

This comparison assumes a like-for-like portfolio and charging basis. Although note that your current portfolio may include investments not currently supported by Freetrade. The illustration assumes up to 12 UK share trades per year in GBP only and does not include FX costs. Growth is compounded monthly using an effective monthly growth rate, and monthly contributions are assumed to be made at the start of each month.

Each month, the model adds your contribution, applies growth, and then deducts trading fees (where applicable), percentage-based platform fees (charged monthly), and any fixed monthly fees. Tax relief is added separately every three months (at the end of months 3, 6, 9, 12, and so on), after growth and before fees in those months. Results are shown annually.

Results are shown as a range of plus or minus 10% around the calculated projection to reflect uncertainty. This range is illustrative only and does not represent a guaranteed minimum or maximum outcome. Trading fees use a fixed trade count and do not reflect individual trading behaviour. The illustration excludes fund ongoing charges, bid-offer spreads, fund dealing charges, and any exit or transfer fees. Investments can fall as well as rise in value, and you could get back less than you invest.

Tax relief assumptions

This calculator assumes basic rate pension tax relief of 20% is added under relief at source. The monthly contribution you enter is treated as a net contribution, and tax relief is modelled as being added in 3-monthly batches (at the end of months 3, 6, 9, 12, and so on). If the illustration ends part-way through a 3-month batch, any earned-but-not-yet-paid tax relief is added to the final value shown (without additional growth applied to that extra amount).

This calculator does not assess your income, tax position, or eligibility for pension tax relief, including annual allowance restrictions, tapered allowance, money purchase annual allowance, or relevant UK earnings rules

Already have a pension? You can transfer your pension to Freetrade

Reasons to transfer

  • Your pension’s value is being eaten away by high costs and commissions.
  • You don’t have visibility on what your pension is invested in.
  • You’ve changed jobs and lost track of your pensions, so you want to consolidate them under one plan.
  • Your investment choices are limited and not aligned with your personal needs.
  • You want a simple, intuitive platform where you can manage your pensions easily.

SIPP rules apply. Tax treatment depends on your personal circumstances and current rules may change. 



A SIPP is a pension designed for people who want to make their own investment decisions. You can normally only access your money from age 55 (57 from 2028). Freetrade currently only supports Uncrystallised Fund Pension Lump Sums (UFPLS) for SIPP withdrawals.

Before transferring, check for any exit fees or loss of benefits from your current provider. Pensions transferred to Freetrade may lose any protected pension age benefit, meaning you may not be able to draw the money until age 57. Seek professional advice if you need help with your pension.

Tax relief

Contributions into your SIPP benefit from 20% - 48% tax relief, depending on your taxpayer rate.

How tax relief boosts your pension

When you contribute to your pension, we automatically claim 20% basic-rate tax relief for you and pay it into your Freetrade SIPP. This usually arrives within 6 to 11 weeks.

For example, if you put in £80, the government tops it up by £20, making £100 in your pension.

If you are a higher or additional rate taxpayer, you may be able to claim extra tax relief through your tax return. This is on top of the 20% basic rate tax relief already added to your pension. Depending on your rate, the total relief can be up to 40% or 45%, or 48% in Scotland.

Pension and tax rules can change, benefits depend on your circumstances, contribution limits apply, and pension access is normally from age 55 (rising to 57 from 2028).
