Free FIFO Inventory Calculator for Accounting Students
Calculator for a textbook exercise—remove.bg, but for homework help.

Instant, no-login CGPA projections with support for multiple national scales and school-specific grade tables — exactly the feature set students actually need during exam season. The shareable result card + PNG export and per-module inputs are practical touches; what it lacks are import/save features (CSV/transcript, scenario saving) and a few power UX flows for counselors or batch use.
Students (undergraduate/college), academic advisors and counselors, exchange/scholarship applicants
It also lets you estimate cumulative results from current CGPA, completed credits, and expected semester grades. It’s free, no sign-up, and mobile-friendly.
I’d really value feedback on:
missing grading scales or country systems confusing parts of the UX features that would make this more useful for students/counselors
Calculator for a textbook exercise—remove.bg, but for homework help.
Nice, focused feature set — salary slider, Scotland tax bands, student loan options, pension relief and employer-cost math are all surfaced without burying the user in jargon. It doesn't invent a new category, but the tax-band visualization and advanced options (tax codes, employer NI) show care; I'd want export/print and privacy/version notes before recommending it widely.
The landing nails the pitch — enormous headline, neon dollar and a single clear CTA make the product instantly understandable. The form intelligently asks age (with a generation-based estimate), country and daily screen time so the friction is minimal; the tradeoff is that the site leans on industry averages without publishing the underlying rates. Useful for a quick viral stat or awareness piece, but it needs a transparent methodology and per-channel breakdowns to feel rigorous.
