Tuition Per-Credit vs Flat-Rate Calculator
Compare paying tuition per credit hour against a flat full-time rate and find the break-even course load.
How it works
Per-credit total = credits × cost-per-credit · Break-even credits = flat rate ÷ cost-per-credit
Many colleges bill part-time students per credit but charge a single flat rate once you cross a full-time threshold. The flat rate is a fixed cost, so its per-credit value falls the more credits you take — which is why heavy course loads favor the flat plan and light ones favor per-credit billing. The break-even point is simply the flat rate divided by the per-credit price: below it, per-credit is cheaper; above it, the flat rate wins and every extra credit is effectively free.
Worked example
At $450 per credit, 15 credits cost $6,750 — more than a $6,000 flat rate, so the flat rate saves $750. The break-even is $6,000 ÷ $450 ≈ 13.3 credits, so anyone taking more than about 13 credits is better off on the flat plan.
Frequently asked questions
When is per-credit tuition cheaper?
When you take fewer credits than the break-even load. Below that point you pay only for what you take, so a light schedule costs less than the fixed flat rate.
What is the break-even course load?
The number of credits at which both options cost the same: flat rate ÷ cost per credit. Above it the flat rate is cheaper; below it per-credit billing is.
Are fees included?
This compares tuition only. Mandatory fees, lab charges and full-time-only fees can shift the comparison, so add them to each side before deciding.
