Timing matters: same refund, different month
What this refund actually does
The catch: this assumes every dollar of the refund goes to debt, not savings or lifestyle. If you plan to split it (say, 70% to debt, 30% to emergency fund), reduce the amount above to match — the result below is based on debt-applied dollars only.

Track every payment against your real plan

The Unburden app lets you log your refund, watch your debt-free date jump forward, and see your Burden Score drop in real time.

Common Questions

Is it better to pay off debt with my tax refund or save it?
If your debt interest rate is above 7–8% (most credit cards, personal loans, payday loans), applying the refund to debt gives you a guaranteed return equal to your APR — better than almost any investment on a risk-adjusted basis. Exception: if you have no emergency fund, keep 1–2 months of essential expenses in savings first, then apply the rest to your highest-rate debt.
How much does timing actually matter?
A lot — because interest compounds on the remaining balance every month. A $2,000 refund applied today saves roughly $180 more on a $10,000 credit card at 22% APR than the same refund applied six months from now. Use the "timing matters" section above to see what your own numbers look like across different months.
What is the average tax refund?
The average 2024 US federal tax refund was about $3,200 (IRS data). The average Canadian refund is around $2,100. If you get a big refund every year, you're lending the government your money interest-free — adjust your W-4 or TD1 to lower withholding and you'll have more per paycheck to apply to debt immediately instead of waiting.
Should I split my refund between debt, savings, and spending?
A common framework for people carrying high-interest debt: 10% fun (so you don't feel deprived), 20% emergency fund top-up (if your fund is under one month of expenses), 70% highest-interest debt. If your emergency fund is already solid and your debt APR is above 15%, putting the full refund toward debt is almost always the highest-return move.
Does this work for bonuses, inheritances, or stimulus payments?
Yes. The math is identical for any one-time windfall — a year-end bonus, gift, inheritance, tax refund, stimulus payment, or lump-sum side-hustle earnings. Only the label says "refund" because that's the most common scenario.
What if I have multiple debts — which one do I hit with the refund?
Mathematically, apply it to the debt with the highest APR (the "avalanche" approach) — that's where interest is burning you fastest, so that's where the dollar saves the most. Psychologically, some people do better wiping out the smallest balance first ("snowball") for the momentum. If you have more than one debt, try the full multi-debt calculator — it runs both strategies side by side.
