Your inputs, not a promise. Late money is worked out at 8%; the law adds the Bank of England base rate, so the real figure is higher.
How it is worked out.
No hidden numbers. The same sums run as you move a slider.
- Hours back
- Each count times its minutes, added up, divided by 60.
- Value
- Hours back times your hourly cost.
- Plan
- The cheapest plan that covers the work, as on the pricing page: client emails and tasks need Growth.
- Difference
- Value of the hours minus the plan. Add-on agents are not included.
- Interest
- Money overdue times 8%, times days late, divided by 365. GOV.UK sets the rate at 8% plus the base rate.
- Fixed sum
- GOV.UK's fixed sum for each late invoice: £40 under £1,000, £70 up to £9,999.99, £100 from £10,000.
