Common questions

Pay Off Debt vs Invest Calculator FAQs

Is repaying debt a guaranteed return?

Interest avoided is generally predictable if the debt rate is fixed and there are no repayment penalties.

Should I invest without emergency savings?

The calculator cannot assess your cash buffer or personal risk.

Does this account for investment tax?

No. Enter a cautious return after expected fees and tax if relevant.
