How the calculator works: the monthly repayment is calculated using the standard amortising-loan formula at a fixed interest rate, with all fees added to the total cost of credit but not amortised into the monthly figure. Real GGS quotes typically include the arrangement fee in the loan principal — so your actual monthly figure can be marginally higher than the model.

How to interpret your GGS calculator output

A few things worth understanding before you use the calculator output for budget planning:

  • The monthly repayment is amortising capital and interest, just like a residential mortgage. Each month a slightly larger portion is capital and a slightly smaller portion is interest.
  • The 2% BBB scheme fee is paid once, at drawdown. We’ve modelled it as a one-off cost added to the total cost of credit but not built into the monthly repayment.
  • The arrangement fee is whatever the lender charges — from zero on some specialist non-bank facilities up to ~3% on some high-street bank deals. In practice many lenders fold it into the loan principal, in which case the actual monthly repayment will be marginally higher than the modelled figure.
  • The interest rate here is a representative APR. Real lender quotes are issued at a specific personal rate following formal underwriting.

FAQs

GGS calculator — FAQs

Is this the same calculator the British Business Bank uses?

No — this is a representative repayment calculator built around our broker panel’s observed pricing for the Growth Guarantee Scheme in 2026. It uses the standard amortising-loan formula. The BBB does not publish a public lender-side calculator.

Why is the actual lender quote slightly different?

Real lender quotes apply a personalised interest rate following underwriting, may roll the arrangement fee into the loan principal, may apply a slightly different repayment basis (e.g. monthly in arrears with first repayment in month 1 vs month 2), and will reflect any pre-agreed payment-holiday or interest-only period.

Does the calculator include the 2% BBB scheme fee?

Yes — if the “Include 2% BBB scheme fee” checkbox is ticked, we add 2% of the loan amount as a one-off scheme fee to the total cost of credit. Untick to compare like-for-like with a non-scheme commercial loan.

Can I model a variable-rate facility?

Not directly — the calculator assumes a fixed rate over the whole term. To approximate a variable-rate RCF (Bank Base Rate + margin), use today’s effective rate as the input figure. Bear in mind a real RCF reprices with changes in BBR.
