About Shorstory — Your Financial Analysis Platform
Shorstory is a dedicated financial calculation platform designed for professionals who need accurate, transparent, and privacy-respecting analytical tools. Every calculator is implemented in client-side JavaScript with publicly documented methodologies — from progressive tax bracket calculations using current IRS tables to defined-benefit pension formula modelling using standard actuarial approaches.
Our philosophy is grounded in financial transparency: the numbers should speak for themselves, and the methodology should be open to scrutiny. We do not obscure calculation logic behind black-box algorithms, nor do we collect, store, or transmit your financial data. Every input you enter — salary figures, tax parameters, service years — remains exclusively on your device, processed in your browser tab and never sent to any server.
Our target users include compensation and benefits professionals conducting offer analysis, HR practitioners modelling severance scenarios, freelance and gig economy workers optimizing rate structures, retirement planners stress-testing pension adequacy, and any individual who prefers data-driven financial decisions over rule-of-thumb estimates.

How Our Calculators Work — Transparent Methodology, Absolute Privacy
Every calculator on Shorstory is built as a client-side JavaScript application with fully transparent calculation logic. When you enter salary data into the tax calculator or service years into the pension estimator, that information is processed exclusively within your browser session. It is never transmitted to any server, stored in any database, or collected by any analytics service. This architecture is a deliberate design choice that eliminates the privacy and security risks inherent in server-based financial tools.
The performance advantage is equally significant: there are no API round-trips, no database queries, no waiting for server-side computation. Results appear instantaneously as the calculations execute locally, enabling rapid what-if scenario modelling that would be impractical with server-dependent architectures.
Our tax engine uses the published 2024 IRS tax brackets, standard deduction amounts, and FICA wage base limits, alongside state-level tax rates that are reviewed and updated annually. The severance module implements the standard N+1 and 2N statutory formulas used across multiple jurisdictions, with configurable parameters for vacation payout and notice-period compensation. The pension estimator applies the conventional defined-benefit formula: salary basis × years of pensionable service × accrual rate, with optional adjustments for plan type and cost-of-living provisions.
Beyond the calculators, our Blog provides in-depth analytical content covering corporate finance, financial accounting, compensation strategy, and retirement planning — written for professionals who want to understand the underlying principles behind the numbers.
