How big will my pension pot be at 67?
On a £35000 salary contributing 8% total (5% employee + 3% employer) starting at age 25: at 5% returns your pot reaches approximately £380000 by 67. At 7% returns: approximately £570000. Increasing your contribution from 5% to 8% (with 3% employer match = 11% total) boosts the pot to approximately £525000-£790000. Every 1% extra contribution adds approximately £60000-£100000 at retirement.
Is my workplace pension enough to retire on?
A £400000 pension pot can provide approximately £16000-£20000 per year plus your state pension (approximately £11500 for full entitlement). Total retirement income: £27500-£31500 per year. If your current spending is £35000+ per year you will need to either increase contributions reduce retirement spending or plan to work longer. The earlier you increase contributions the less it costs per month to reach your target.
How much should I contribute to my pension?
A common rule of thumb is to contribute half your age as a percentage starting from when you begin saving. If you start at 25 contribute 12.5% of salary. At 30 contribute 15%. At 40 contribute 20%. These targets assume retirement at 67. Contributing less means either a lower retirement income working longer or relying more heavily on the state pension which may not provide the lifestyle you want.
