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 Bank of England base rate +1% minimum interest, and the 5-year maximum term — flagging any breach in real time. Calculations are indicative; verify the current BoE Bank Rate at drawdown.

How the calculator validates HMRC compliance
Every calculation runs four real-time checks against the HMRC loanback framework set out in Pensions Tax Manual PTM121000:
- 50% asset rule: the proposed loan amount must not exceed 50% of net SSAS scheme assets at inception.
- Minimum interest rate: at least Bank of England base rate + 1%. The default 5.75% reflects current base 4.75% — verify on actual drawdown.
- 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 verify the other two HMRC rules (first legal charge security + full documentation), because those depend on the underlying assets and loan agreement — both are mandatory and explained in the full guide.
