Variance analysis

A method of budgetary control that compares actual performance against plan, investigates the causes of the variance and takes corrective action to ensure that targets are achieved.

Return on Total Assets Ratio

A measure of the percentage return earned on the value of the
assets in the company. It is calculated by dividing the net income
available for distribution to shareholders by the book value of all
assets.

Total Asset Turnover Ratio

A measure of the utilization of all of a company's assets to
generate sales. It is calculated by dividing the sales figure for the
period by the book value of the net fixed assets.

Total Debt to Total Assets Ratio

See debt ratio

Variance

The weighted average of the squared deviations from the
expected value

the difference between total actual overhead
and budgeted overhead based on standard hours allowed
for the production achieved during the period; computed
as part of two-variance overhead analysis; also
referred to as the controllable variance

controllable variance

the budget variance of the two variance approach to analyzing overhead variances

achieved multiplied by the standard rate to establish
a value for efficiency (favorable) or inefficiency (unfavorable)

(actual mix X actual hours X standard rate) - (standard mix X actual hours X standard rate);
it presents the financial effect associated with changing the
proportionate amount of higher or lower paid workers in production

the actual rate (or actual weighted average rate) paid to labor for the period minus the standard rate multiplied by all hours actually worked during the period;
it is actual labor cost minus (actual hours X standard rate)

(standard mix X actual hours X standard rate) - (standard mix X standard hours X standard rate);
it shows the monetary impact of using more or fewer total hours than the standard allowed

material price variance

total actual cost of material purchased
minus (actual quantity of material  standard
price); it is the amount of money spent below (favorable)
or in excess (unfavorable) of the standard price for the
quantity of materials purchased; it can be calculated based
on the actual quantity of material purchased or the actual
quantity used

material quantity variance

(actual quantity X standard price) - (standard quantity allowed  standard price);
the standard cost saved (favorable) or expended (unfavorable)
due to the difference between the actual quantity
of material used and the standard quantity of material
allowed for the goods produced during the period

material mix variance

(actual mix X actual quantity X standard price) - (standard mix X actual quantity X standardprice);
it computes the monetary effect of substituting a nonstandard mix of material

material yield variance

(standard mix X actual quantity X standard price) - (standard mix X standard quantity X standard price);
it computes the difference between the
actual total quantity of input and the standard total quantity
allowed based on output and uses standard mix and
standard prices to determine variance

noncontrollable variance

the fixed overhead volume variance;
it is computed as part of the two-variance approach to overhead analysis

overhead efficiency variance

the difference between total budgeted overhead at actual hours and total budgeted
overhead at standard hours allowed for the production
achieved; it is computed as part of a three-variance analysis;
it is the same as variable overhead efficiency variance

overhead spending variance

the difference between total actual overhead and total budgeted overhead at actual
hours; it is computed as part of three-variance analysis; it
is equal to the sum of the variable and fixed overhead

and is unfavorable if actual is greater than standard

variance analysis

the process of categorizing the nature (favorable or unfavorable) of the differences between standard and actual costs and determining the reasons for those differences

the difference between budgeted fixed overhead and fixed
overhead applied to production of the period; is also referred
to as the noncontrollable variance

Covariance

A measure of the degree to which returns on two assets move in
tandem. A positive covariance means that asset returns move together; a
negative covariance means they vary inversely.

Variance

The dispersion of a variable. The square of the standard deviation.

the unit cost of each item, excluding all other variables.

The difference between the amount of time that was budgeted
to be used by the direct labor staff and the amount actually used, multiplied
by the standard labor rate per hour.

The difference between the actual and standard direct labor rates
actually paid to the direct labor staff, multiplied by the number of actual hours
