Education pays: a college degree adds an average of $1 million in lifetime earnings over a high school diploma, but the cost has tripled in real terms since the 1980s, and student loan debt in the U.S. has crossed $1.7 trillion. Education calculators help you model the long-term return on tuition investment, project college savings growth, plan loan payoffs, and convert grades across systems. Every formula is grounded in NCES, Federal Student Aid, and Common Data Set standards, and runs in your browser so academic records and financial data stay private.
How to choose the right education calculator
The college savings calculator (529 plan, Coverdell ESA, UGMA/UTMA) projects growth under different contribution scenarios. The student loan calculator estimates monthly payments under standard, graduated, and income-driven repayment plans. The GPA calculator converts between 4.0, 4.3, 5.0, and 10.0 scales, and computes weighted and unweighted GPAs. The tuition inflation calculator projects future college costs based on historical 5-6% annual increases. The financial aid calculator (FAFSA EFC, now SAI) helps estimate eligibility for need-based aid. The return on education calculator compares lifetime earnings by degree level and field of study to help you make a data-driven decision about whether a graduate degree pays off.
College savings: 529 plans, Coverdell, and UGMA
A 529 plan offers tax-free growth and tax-free withdrawals for qualified education expenses. The 2026 contribution limit is $19,000/year per donor ($38,000 for married couples) without gift tax, with 5-year forward gifting allowing up to $95,000 in one year. State tax deductions vary: 36 states offer income tax breaks on contributions. The college savings calculator projects balance at age 18 under different monthly contributions and assumed returns. The Coverdell ESA allows $2,000/year in contributions with broader expense coverage (including K-12) but lower income limits ($95K-$110K MAGI for full contribution, phase-out to $110K-$125K). The UGMA/UTMA accounts are flexible but count more heavily in financial aid calculations.
Student loans, repayment, and forgiveness
The federal student loan calculator uses the standard 10-year repayment formula: monthly payment = principal x [r(1+r)^n] / [(1+r)^n - 1], where r is the monthly interest rate and n is 120 months. The Income-Driven Repayment (IDR) calculator handles IBR, PAYE, REPAYE, and ICR plans that cap payments at 10-20% of discretionary income, with forgiveness after 20-25 years. Public Service Loan Forgiveness (PSLF) calculator models forgiveness after 120 qualifying payments while working for a qualifying employer. The student loan refinance calculator compares federal versus private rates, and the consolidation calculator shows the impact of combining multiple loans. Total and Permanent Disability (TPD) and Teacher Loan Forgiveness (TLF) are modeled as edge cases.
GPA, grades, and academic planning
The GPA calculator handles the four most common U.S. scales: 4.0 (standard), 4.3 (honors), 5.0 (weighted AP/Honors boost), and 10.0 (international IB and some Canadian schools). It computes both semester and cumulative GPA, including weighted grades for AP, IB, and honors courses. The grade converter translates between percentage, letter grade, and 4.0 GPA. The class rank calculator shows how GPA translates to percentile rank within your school. The college admissions calculator helps estimate chances based on GPA, test scores, and extracurriculars, using historical admit rates from Common Data Set. The study time calculator projects time required to raise your GPA by a target amount.
Return on education: degree ROI by field
The ROI of a college degree is field-dependent. STEM degrees (engineering, computer science, nursing) typically have 10-year ROIs of 200-400%. Liberal arts and education degrees have ROIs of 50-100% over a 20-year horizon. Graduate degrees generally pay off for law, medicine, MBA, and PhD fields, but not for some terminal master's programs. The return on education calculator compares lifetime earnings by degree level and field using BLS, Census, and NCES data. The break-even calculator finds the age at which higher education costs are recovered through higher earnings, typically 30-40 for bachelor's degrees, 35-45 for graduate degrees. The salary premium calculator shows the wage gap between degree levels in your specific field.

Frequently Asked Questions
How much should I save for my child's college? ▾
A common target is 50% of projected four-year costs, with the rest covered by current income, grants, scholarships, and student loans. For a child born in 2026, a four-year public college could cost $200,000-$300,000 in 2044; private could exceed $500,000. The 529 calculator projects savings growth under different monthly contributions.
How do I pay off student loans faster? ▾
Pay more than the minimum: even $50 extra per month on a $30,000 loan at 6% saves $2,000 in interest and 1.5 years. Refinancing to a lower rate works if you have good credit and stable income. Income-driven repayment plans lower monthly payments but extend the term; consider refinancing only after you have a stable job and good credit.
What is PSLF and is it worth it? ▾
Public Service Loan Forgiveness forgives remaining federal student loan debt after 120 qualifying payments (10 years) while working full-time for a qualifying employer (government, 501(c)(3) non-profit, public service). The PSLF calculator shows your specific forgiveness amount and break-even point.
How is weighted GPA calculated? ▾
Weighted GPA adds extra points for advanced courses. A typical scale: regular courses on 4.0 scale (A=4.0), honors on 4.5, AP/IB on 5.0. A 4.0 in a regular class and 4.0 in an AP class have different weight: the regular A counts as 4.0, the AP A counts as 5.0. The GPA calculator handles all common weighting schemes.
Is college still worth it? ▾
On average, yes: bachelor's degree holders earn 65% more than high school graduates over a lifetime. But the ROI varies hugely by field, school, and career path. The return on education calculator shows the specific break-even age and lifetime earnings premium for your chosen field and school.
