I knocked up this little spreadsheet to help people determine if they are on course to exceed the pension LTA:
https://docs.google.com/spreadsheets/d/1MT8CtQsNWSDkDlUFFUk4U-3bpxV3hab9qVaXFWdm_eQ/edit#gid=2069368132I think that there is a "danger" that too much focus on your pension too soon could quite easily result in hitting the LTA before you reach pension access age.
We know that money compounding at 7% doubles every 10 years, and money compounding at 10% doubles every 7 years. If you are, lets say, 40 years old and have been smashing the pension contributions for the last few years and have already amassed let's say £200k there.. you are still 18 years from retirement and it's quite conceivable that just a couple more years heavy contributions could put you on course to hit the LTA.
I mean, this is a nice problem to have in theory... but it is a problem nonetheless.
This is what I'm currently juggling with. While I still have 14 years until I can access my pension, and "only" about £227k in my pension right now but I figure that maybe as few as another 4 years of maxing out my pension, combined with the internal growth could put me on course to exceed the LTA.
You can also factor in the "free" £720/pa you can get by contributing £2880 which the govt will gross up to £3600 even if you are FI and with no income (so eg you can move money across from your ISA) which all helps at the margins.
This exercise has also completely convinced me against making any additional J-SIPP contributions, as while the idea of 58years' of compounding would be awesome, it also means that my child would basically never be able to get her own tax breaks, so I put solely into her J-ISA instead.
