Debt-to-Income (DTI) Calculator
All monthly debt payments against income — the lender's headline ratio and your borrowing headroom.
Formula
DTI is the gate to every loan — lenders cap total obligations around 40-50% of income (FOIR in India). Below 36% you borrow on the best terms; above 43% doors close. Unlike net worth, DTI measures cash-flow strain, not wealth — high earners with high EMIs can still be fragile.
