Formula and worked example
For each option, multiply a monthly quote by 12 or use the annual quote once. Add each one-off charge once. Subtract the current total from the proposed total. The separate labour adjustment is 12 × change in monthly admin hours × hourly labour cost.
Example only. Current: £1,000 per month and £0 one-off. Proposed: £1,100 per month and £500 one-off. The 12-month totals are £12,000 and £13,700, a difference of £1,700 more. Saving two admin hours a month at £50 per hour gives a labour-adjusted difference of £500 more.
