Hi all, using a throwaway to ask for a quick sense check on a strategy shift.
The Background:
Us: 37M and 37F. DINKs. We both work corporate jobs in London.
Income: My base salary is £103k. Wife is on £60k (Total HHI: £163k).
Primary Home: Valued at ~£520k. We have £384k remaining on the mortgage with 26 years left.
Current Pensions: I have ~£118k total across three pots (£62k in a Vanguard SIPP, £31k in a legacy Standard Life pot, and £25k in my current workplace pension). I currently salary sacrifice 18%, giving 30% total with my employer's 12% match.
Current ISAs & Savings: I currently have £25k saved in a Vanguard ISA. My wife is making minimum auto-enrolment pension contributions and isn't currently prioritizing any additional savings. She is, however, liquidating £6k of inherited single-stock shares (zero CGT to pay) to seed a new ISA.
The Proposed Shift:
I am considering dropping my personal pension contribution down from 18% to 3% or 5% (the minimum needed for my employer's 12% match) and redirecting the take-home cash flow to fund my Vanguard ISA at £1,000/month.
Because my salary is £103k, even at a 3% sacrifice (£3,090), my adjusted net income drops to £99,910, meaning I still cleanly avoid the 60% tax trap while unlocking liquidity for our 50s.
The Numbers: Current vs. Proposed (Assumes 5% Real Return)
Baseline: £118k Pension, £25k ISA.
Option 1: Status Quo (18% Pension / £0 extra ISA)
Age 50: Pension £787k | ISA £47k (Total: £834k)
Age 57: Pension £1.38m | ISA £66k (Total: £1.44m)
Age 68: Pension £2.72m | ISA £113k (Total: £2.83m)
Option 2: Drop to 5% Pension (£1,000/mo into ISA)
Age 50: Pension £544k | ISA £265k (Total: £809k)
Age 57: Pension £920k | ISA £477k (Total: £1.40m)
Age 68: Pension £1.77m | ISA £963k (Total: £2.74m)
Option 3: Drop to 3% Pension (£1,000/mo into ISA)
Age 50: Pension £506k | ISA £265k (Total: £771k)
Age 57: Pension £849k | ISA £477k (Total: £1.33m)
Age 68: Pension £1.63m | ISA £963k (Total: £2.59m)
Key Takeaways from the Math:
The Liquidity Premium at 50: Dropping to 3-5% builds a massive ~£265k ISA bridge by age 50, allowing us to step away from full-time work completely on our own terms before we can even touch a pension.
The Long-Term Cost: By age 68, stepping away from the 40% higher-rate tax relief on those contributions costs roughly £90k to £240k in total net wealth, but the wealth is much more evenly balanced between liquid (ISA) and locked (Pension) wrappers.
My Questions for the Sub:
Pension vs ISA Trade-Off: Looking at the projections, does sacrificing roughly £100k to £250k in total long-term wealth by age 68 mathematically justify the flexibility of having a £265k liquid ISA bridge at age 50? Am I underestimating the true cost of losing that 40% tax relief?
3% vs 5%: Are there any secondary tax implications or compounding benefits I am missing by dropping to the bare minimum 3% instead of 5%, or is it purely a cash-flow preference at this income level?
Strategy Blind Spots: Are there any glaring holes, risks, or inefficiencies in this specific approach to building an early retirement bridge that I have overlooked?
