Flat-Rate EMI vs Reducing-Balance Loan
**Flat-rate** loans charge interest on the original principal for the full term—EMI looks low but effective APR is higher. **Reducing-balance** (standard amortizing) interest drops as principal is paid down—this matches most mortgages and auto loans in the U.S.
Step by step
1. Ask for reducing-balance APR
Compare effective rate, not just advertised flat %.
2. Sum total interest
Multiply flat EMI × months and subtract principal—compare to amortizing total.
3. Check prepayment rules
Flat products may penalize early payoff more aggressively.

- Flat rate: Simpler quote; higher true cost on long tenures.
- Reducing balance: Standard amortization; fairer interest on declining principal.
