Should You Pay Off Your Student Loans or Invest? What San Diego’s High Earners Often Get Wrong

Should You Pay Off Your Student Loans or Invest? What San Diego’s High Earners Often Get Wrong

June 25, 2026

Trying to decide whether to pay down debt or invest?

This is one of the first conversations we have with high earning professionals in a HENRY Strategy Session. If you want to walk through your situation with a clear framework, you can schedule a time here.

You have a $340,000 dental school loan at 6.8%.

You also have a bonus sitting in your checking account.

Your gut says pay down the debt. A colleague says you should be investing instead. Your CPA mentioned something about taxes, but you are not entirely sure how it applies.

This is one of the most common financial crossroads for high earning professionals in San Diego.

The challenge is that the appropriate answer is almost never the one that sounds simplest.

This post walks through the framework behind that decision, so you can approach it more clearly, and have a more productive conversation with your advisor.

Why This Question Doesn’t Have a Universal Answer

There is no one size fits all answer to the “pay off debt or invest” question.

  • The interest rate on your debt
  • Expected investment return assumptions
  • Whether your interest is tax deductible
  • Access to employer retirement matches
  • Your income trajectory
  • Your personal relationship with debt

The Math Starting Point, Interest Rate vs Expected Return

At a high level, this is an arbitrage question.

Debt RateGeneral Interpretation
3 to 4 percentOften favors investing over time
5 to 6 percentClose decision, depends on taxes and cash flow
7 to 8 percent or higherPaying down debt often becomes more compelling

The California Tax Consideration

  • Student loan interest deductions often phase out at higher income levels
  • Mortgage interest may still be partially deductible
  • Pre tax retirement contributions reduce taxable income

This is why coordination between tax strategy and financial planning becomes more important for high earners.

The Employer Match Exception

If your employer offers a match and you are not capturing it, that is typically the first place to start.

An employer match often represents a 50 to 100 percent return.

The Psychological Variable

Carrying large debt impacts behavior, risk tolerance, and decision making.

Paying down debt faster than required can be a rational choice if the psychological benefit is meaningful to you.

A Framework for San Diego’s High Earners

  • Capture the full employer match
  • Address high interest debt
  • Maximize tax advantaged accounts
  • Evaluate mid range debt alongside investing
  • Consider refinancing where appropriate
