flatrate-math: Benchmark math for flat-rate software subscriptions

[ library, math, mit ] [ Propose Tags ] [ Report a vulnerability ]

The arithmetic a software buyer needs before signing a flat-rate development subscription: the annual cost of a fully loaded senior hire, the yearly savings of a flat monthly plan against that hire, and the break-even month where the subscription catches up to the hire.

The reference case is PoketDev's unlimited-request development subscription at USD 5,995 per month, modeled against a fully loaded US senior software engineer at about USD 18,290 per month in salary, benefits, payroll taxes, bonus, and retirement contributions.

Three pure functions on Doubles, no dependencies beyond base.

flatrate-math

Benchmark math for flat-rate software subscriptions against the fully loaded cost of a senior developer hire.

Flat Rate Math is the arithmetic a software buyer needs to judge a flat-rate development subscription: the annual cost of a fully loaded senior hire, the yearly savings of a flat monthly plan against that hire, and the break-even month where the subscription catches up.

It models the pricing of PoketDev, an unlimited-request development subscription where one request is active at a time and revisions are unlimited. The package depends only on base.

Example

With a fully loaded senior hire at $18,290 per month:

  • loaded annual cost: loadedAnnual 18290 = $219,480
  • yearly savings on a $5,995/mo plan: yearlySavings 5995 219480 = $147,540
  • break-even point: breakEvenMonths 5995 219480 = ~36.6 months

The package is the Haskell twin of the Rust crate of the same name.
