Pelayanan kontrasepsi IUD dan implants selain berdampak pada penurunan fertilitas juga berdampak pada pembiayaan terutama biaya bersumber dari pemerintah. Oleh karena itu perlunya dilakukan evaluasi ekonomi untuk mengetahui efektifitas biaya metode kontrasepsi IUD dan implant dengan menggunakan metode CEA (cost effectiveness analysis) karena metode CEA merupakan instrumen yang optimal untuk mengetahui efektivfitas biaya suatu program.Penilitian ini merupakan penelitian kuantitatif untuk memperoleh nilai CER (cost effectiveness ratio) metode kontrasepsi IUD dan implant, desain penelitian cross sectional untuk memperoleh data biaya secara bersamaan pada provider dan acceptor. Perhitungan biaya provider dilakukan dengan metode ABC (activity based costing) dan distribusi sederhana.Penelitian ini menghasilkan informasi provider mengeluarkan biaya untuk pelayanan kontrasepsi IUD dan implant masing-masing sebesar 55,2% dais 44,48% dari total biaya provider. Akseptor mengeluarkan biaya untuk menggunakan metode kontrasepsi IUD dan implant masing-masing sebesar 46.8% dan 53,2% dari total biaya akseptor. Komponen biaya provider terbesar adalah biaya operasional 99,95% dan komponen biaya akseptor terbesar adalah biaya retribusi jasa medis, alat kontrasepsi dan obat 76,34%.Sebelum dan setelah dilakukan analisis sensitihtas, nilai CER (cost effectiveness ratio) metode kontrasepsi IUD tetap lebih kecil dibanding implant. Berarti metode kontrasepsi ND tetap lebih cost efektif. Agar pelayanan kontrasepsi di puskesmas lebih efektif, perlunya meningkatkan efektifitas dan efisiensi penggunaan biaya dan manajemen pelayanan kontrasepsi.
