The RDN Debt Reality Calculator

Residual = Wage − Annual debt service − (Tax × Wage) − Annual cost of living

• Federal tranche: first $71,000 of total cost ($20,500/yr unsubsidized cap × a typical 3–3.5-year MS + supervised-practice sequence; the $100,000 lifetime cap binds later). Rate: AY 2025–26 graduate unsubsidized, 7.94%.
• RAP: the statutory applicable percentage of AGI by $10,000 band (1%–10%, $10/mo minimum). At $77,130, the >$70–80K band → 7% → $5,399/yr ($450/mo). The dependent-child offset ($50/mo per child) is not modeled — results are conservative for parents.
• Private tranche: remainder above $71,000, 10-year amortization at 9% (≤$50K), 10% ($50–150K), or 11% (>$150K) — consistent with current private graduate-loan pricing for typical credit profiles.
• Standard amortization: monthly = P·r(1+r)ⁿ / ((1+r)ⁿ − 1), n = 120.

• Wages: BLS Occupational Employment & Wage Statistics, May 2025 (released May 15, 2026). RDN = SOC 29-1031; state means from the same release. Peers: PT $105,280 · RN $101,420 · OT $101,280 · SLP $98,170 · RT $87,300 · NP $137,300 · PA $141,280.
• Law: One Big Beautiful Bill Act, P.L. 119-21 (signed July 4, 2025; loan provisions effective July 1, 2026). Grad PLUS elimination; $20,500/yr + $100,000 lifetime graduate caps ($50K/$200K professional); RAP replaces SAVE/PAYE/ICR for new borrowers.
• Professional-degree list: 34 CFR §668.2 — dietetics is not included (nor are PT, OT, SLP, nursing).
• Rates: AY 2025–26 graduate unsubsidized 7.94% (Federal Student Aid).
• Budgets: $35,000 conservative-urban and $42,000 major-metro locked-model anchors; 22% = tax-year-2025 federal marginal bracket for single filers ($48,475–$103,350, Rev. Proc. 2024-40); 28% inclusive sensitivity.
• Current cost-of-living presets: MIT Living Wage Calculator (2025 data, updated Feb 15, 2026), single adult, basic expenses excluding taxes — all 51 statewide values embedded (e.g., Florida $42,711; Ohio $36,886; West Virginia $33,999; California $51,416) plus metro examples: Orange County FL $44,633; San Francisco County $54,682; New York County $61,844 (livingwage.mit.edu). Statewide aggregates run below large-metro costs within the same state.
• Wage percentiles: BLS OEWS May 2025 national annual percentiles for SOC 29-1031 — 10th $49,090, 25th $63,080, median $76,400, 75th $89,340, 90th $103,720 (BLS OEWS Occupation Profiles).
• Pipeline context: ACEND (enrollment across all accredited program types 24,423 → 14,170, 2014–2024, −42% with FEM-reclassification caveat — the Didactic Program in Dietetics series alone is 17,719 → 7,732; 2,405 unfilled DI positions in 2024); master's requirement for CDR exam eligibility effective Jan 1, 2024.

At the national mean wage ($77,130), RAP on the federal tranche, 22% tax:

Cost ranges reflect the financed credential (tuition + supervised practice + financed living). The frequently cited $185,000–$336,000 figure is the all-in credential cost including undergraduate and opportunity cost — a different quantity from the financed principal modeled here.

For 2026, in many metros — yes, deliberately. The $35K/$42K anchors are the budgets used in the peer-review model, chosen lean on purpose: if the credential's math fails at a conservative budget, the conclusion is a lower bound that critics can't attribute to inflated living costs. Current data runs higher:

The MIT basket covers food, housing, transportation, medical, civic engagement, internet & mobile, and other necessities (taxes excluded here because the model subtracts taxes separately). Data updated February 15, 2026. Use the MIT presets above or enter your own number — at current metro costs, the residuals are worse than the locked model shows.

What the MIT basket can miss (read this if you're in Florida, Louisiana, or another high-insurance state): housing is a renter model built on county-level HUD Fair Market Rents — homeowners insurance, property taxes, flood coverage, and HOA fees are not in the basket, and insurance-driven rent increases flow in only with a lag. Auto insurance is included but only as a regional average (Consumer Expenditure Survey regions), so state outliers — Florida auto premiums being a prime example — are smoothed toward the regional mean. Medical premiums are state-specific; food is a national baseline. Net effect: in high-insurance states these budgets are floors. If your real costs run higher, enter them in the custom field — every number on the page updates instantly.

State means average everyone — including practitioners with 10–30 years of tenure. New graduates enter near the bottom of the distribution. BLS May 2025 national annual percentiles for SOC 29-1031:

The career-stage toggle estimates early-career pay as your state's mean × the national percentile-to-mean ratio (25th: ×0.818, 10th: ×0.636) — an approximation, since state-specific percentile distributions vary. The implication is direct: every result on this page is optimistic for a new graduate — the cohort actually facing the post-OBBBA loan architecture.

• Educational estimates in nominal dollars for a single filer — not financial, legal, or tax advice. Your loan terms, credit pricing, household structure, and state taxes will differ.
• RAP is a 30-year plan with eventual forgiveness; this model shows the annual cash cost during repayment, not lifetime cost or forgiveness value. PSLF (for qualifying nonprofit/government employment) is not modeled and can change the picture substantially.
• State wages are means, not entry wages — use the career-stage toggle for early-career estimates (national-ratio approximation; state percentile distributions vary).
• The RAP dependent-child offset is excluded (conservative). The 22%/28% toggles bracket the effective-tax question rather than computing a full tax return.
