FTE Calculations and Budget Variance Analysis Guide
Two sections of calculations, and the marks sit in what the assignment demands around them: the formula written out first, cited per formula, and a written interpretation of every result.

A maths assignment that is graded on the writing around the maths
Most of the failure in this assignment happens before any arithmetic. Read the instructions again and notice three rules that are unusual enough to be deliberate. Standard rounding applies, and it applies to the final answer rather than to every intermediate step, so carry decimals through and round once. Units must stay consistent, and the assignment says so because hours and FTEs are the single most common place people lose marks — a full-time equivalent is 2,080 paid hours a year or 40 hours a week, and converting in the wrong direction produces an answer that looks plausible and is wrong by a factor of forty. And every formula must be written out before the numbers go into it, with the source cited for that specific formula, not once at the top of the section. That last rule is stated explicitly with a worked example, which means it is being marked.
The second section, variance analysis, is where the writing matters more than the maths. Total variance decomposes into volume, efficiency and cost components, and the whole point of decomposing it is that the three tell different management stories. A volume variance means the census moved and the budget did not; that is a forecasting problem. An efficiency variance means hours per patient day drifted from target; that is a staffing or acuity problem. A cost variance means the rate paid per hour moved, which usually points at overtime or agency use. Say which one dominates, then say what a manager should actually do about it. Note also that a favourable variance is not automatically good news — coming in under budget on nursing hours while the census rose is a red flag, not a win, and saying so is the kind of interpretation this assignment is looking for.
Likely learning objectives
Inferred from the brief — check these against your own rubric.
- 01Convert accurately between hours, shifts and full-time equivalents.
- 02Project FTE requirements from a change in unit census.
- 03Decompose a total budget variance into volume, efficiency and cost components.
- 04Interpret each variance as a management problem rather than as a number.

Course-wide instructions that accompany this question
You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes. Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages. Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor. The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
Turn the brief into deliverables
- 01FTE calculations shown step by step.
- 02A projection of future FTE needs tied to census change.
- 03Variance calculations for the second scenario.
- 04A written interpretation of each section's findings.
- 05Every formula written out before its numbers, each cited to its own source.
FTEs first, then projection, then variance and its story
Setting up the units
State your FTE definition and the hours it implies before calculating anything.
Current FTE calculation
Work the multistep calculation for the unit as it currently runs.
Projecting FTE needs from census change
Scale the requirement to the projected census and state the assumptions.
Calculating the variances
Compute volume, efficiency and cost variance and check they sum to the total.
What the variance means for the manager
Interpret the dominant variance as an operational problem with an action.
Sourcing a formula, not just a number
Recommended databases
- The assigned Rundio budgeting text
- Healthcare Financial Management Association
- NCBI Bookshelf
- PubMed Central
Search sequence
- 1.Take each formula from the assigned text and record its page so the per-formula citation is easy.
- 2.Check any second source's definition of FTE against the one your course uses before mixing them.
- 3.Look for evidence on staffing levels and outcomes to support the interpretation sections.
- 4.Do not substitute a general finance formula where the course has given a nursing-specific one.

Review before submission
Common mistakes
- Rounding at every intermediate step instead of once at the end.
- Mixing hours and FTEs, or weekly and annual figures, inside one calculation.
- Citing the textbook once at the top instead of against each formula, as instructed.
- Reporting a favourable variance as good news without checking what the census did.
Submission checklist
- Is each formula written out in symbols before any numbers appear?
- Does every formula have its own citation?
- Are all units labelled — hours, FTEs, days, months?
- Does each section end with an interpretation, not just an answer?
