Proximate determinants influence level of fertility in a society. The aim of this study were to estimate the total fertility rate (TFR) for a given level of contraceptive prevalence rate (CPR) and estimate the CPR, some indices and factors for achieving the target TFR. For this, data were extracted from Bangladesh contraceptive prevalence survey, Bangladesh fertility survey and Bangladesh demographic and health survey. Linear regression analysis and revised Bongaarts’ models were used to estimate proximate determinants for achieving target TFR. The regression coefficient demonstrated that TFR has been decreasing while CPR increasing during the investigated period with highly negatively associated between TFR and CPR (p<0.01). The results indicate that to achieve replacement level of fertility at 2.1 births per woman it should be increased the CPR, singulate mean age at marriage, duration of breastfeeding and amenorrhea period at 68%, 20.80 years, 37 months and 2.37 months respectively.
