Save or invest calculator

Compare cash savings with an illustrative investment one day at a time. Add deposits, withdrawals and rate changes on the dates they happen.

1

Starting point

Set the amount, date and length of the comparison.

2

Regular contributions

Use a negative amount to model regular withdrawals.

Contribution changes

Change the amount or frequency from any date.

3

Rates and growth

Enter AER for cash and an illustrative annual growth rate for investments.

Use lower, intermediate and higher return scenarios to explore a range of possible outcomes rather than relying on a single forecast. Which scenario is appropriate to focus on will depend partly on the level of investment risk you are comfortable taking and, importantly, your capacity to absorb losses if markets perform poorly. Higher potential returns generally involve accepting greater uncertainty and a greater risk of loss, so the return assumption should reflect the type of investment and your own circumstances rather than simply choosing the highest rate. For context, the FCA projection rules cap nominal illustration rates at 2%, 5% and 8% for certain tax-exempt and pension products. These are maximum illustration rates, not expected returns or recommendations, and different products may use different assumptions.

Dated deposits and withdrawals

Add deposits as positive amounts and withdrawals as negative amounts.

No dated changes added.

Savings rate changes

Each new rate applies from its selected date.

No dated changes added.
