How to use it

  2. Press Calculate to see the result.
  3. Read the formula, variables, assumptions and source below the result before you rely on it.

Formula

Retainer fee = Included hours × Standard rate × (1 − Discount); Effective rate = Retainer fee ÷ Included hours

Common questions

Formula, source and verification

The retainer is the discounted value of the hours it reserves, with the effective rate shown so the discount is explicit.

The question it answers: What should a monthly retainer cost, and what do extra hours cost?

The formula

Retainer fee = Included hours × Standard rate × (1 − Discount); Effective rate = Retainer fee ÷ Included hours

HIncluded hours
(h). Hours reserved each month.
RStandard rate
(currency/h). Rate charged outside a retainer.
dRetainer discount
(%). Optional discount for committing to the retainer.
VOverage rate
(currency/h). Optional rate for hours beyond the retainer.
KMonthly delivery cost
(currency). Optional cost of delivering the retainer.

Units: Hours; currency per hour; currency; percentages.

What kind of calculation this is

Business input model. The answer depends on business figures only you can supply, such as your own costs, rates or volumes. No market or benchmark values are assumed for you.

Method

The discount and every rate are entered by the firm. When no overage rate is given the standard rate is shown, and the profit line is left uncalculated unless a delivery cost is entered.

Assumptions built into the result

  • Mathematical: The included hours are reserved whether used or not.

Figures this calculator will never guess for you

  • No industry-average rate, margin, overhead or ticket volume is inserted.
  • No optional component is filled in on the user's behalf.
  • No standard retainer discount is assumed.

Limitations

  • Prices the commitment, not the value delivered; unused hours policy has to be agreed separately.
