Work out your SSAS loanback in seconds
Enter your scheme’s net assets, proposed loan amount, interest rate and term below. The calculator works out the annual repayment, total interest paid back to your pension, and a full year-by-year amortisation — and flags any breach of the five HMRC loanback rules in real time.
The SSAS loanback calculator below computes your annual repayment, total interest paid, and full amortisation under HMRC’s loanback rules. It validates against the 50% net-asset limit, the interest rate of 1% above the average of the base lending rates of six named high-street banks, and the 5-year maximum term — flagging any breach in real time. Calculations are indicative; check the six banks' rates on the day of drawdown .

How the calculator validates HMRC compliance
Every calculation runs checks against the HMRC loanback framework set out in Pensions Tax Manual PTM123200 :
- 50% asset rule: the proposed loan amount must not exceed 50% of net SSAS scheme assets at inception.
- Minimum interest rate: at or above the HMRC prescribed rate (you confirm). The prescribed rate is 1% above the average base lending rate of six leading UK banks, rounded up to the nearest 0.25%. There is no single published figure: check the six banks' rates on the day of drawdown. The default in the calculator is illustrative only.
- Maximum 5-year term: the loan must be repaid in equal annual instalments over no more than 5 years.
- Equal-instalment validation: the “Total payment” column shows the same figure every year, confirming compliance with the “equal annual instalments of capital and interest” rule under Finance Act 2004 Schedule 30.
The calculator doesn’t check security or loan documentation, because those depend on the loan agreement. The loan must be secured. We work through the options with you.
