HR Software Monthly and Annual Cost Estimator

This estimator turns a per-employee price range into a monthly and annual budget. Pick a plan type to load an illustrative range, or type the numbers from a written vendor quote. Then enter how many employees will be on the plan and any charges that do not scale with headcount, such as a monthly base fee, a flat-priced module or a support package.

Formula: monthly cost = (employees x price per employee) + fixed monthly charges. The low and high results use the low and high per-employee prices. Multiply by 12 for a yearly figure.

Worked example (illustrative): 25 employees at $8 to $20 per employee plus $80 in fixed charges gives a low of 25 x 8 + 80 = $280 and a high of 25 x 20 + 80 = $580 per month, or $3,360 to $6,960 per year.

Limits: the ranges are rough budgeting bands, not vendor prices, and actual pricing varies widely. The tool leaves out one-time setup, data migration, per-payroll-run fees, state tax filing fees, taxes, discounts and annual increases. Many vendors also set a minimum monthly charge, so a very small team may pay more than the formula suggests. Always compare against a written quote.
