Common choices include:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><strong>Direct Labor Costs\u00a0<\/strong>\u2013 Often used for fringe and overhead<\/li>\r\n\r\n\r\n\r\n<li>Total Cost Input (TCI)\u00a0\u2013 Frequently used for G&amp;A<\/li>\r\n\r\n\r\n\r\n<li>Direct Labor Hours\u00a0\u2013 Useful if you have labor-driven contracts<\/li>\r\n\r\n\r\n\r\n<li>Modified Total Direct Costs (MTDC)\u00a0\u2013 Used in some federal agreements<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>Choosing the correct base is critical. It must reflect the activity that drives the cost pool, it\u2019s a compliance issue if it doesn\u2019t.<\/p>\r\n\r\n\r\n\r\n<p>Step 3: Do the Math<\/p>\r\n\r\n\r\n\r\n<p>Here\u2019s the simplified formula you\u2019ll use for each indirect rate:<\/p>\r\n\r\n\r\n\r\n<p>Indirect Rate (%) = (Projected Indirect Costs) \u00f7 (Projected Allocation Base)<\/p>\r\n\r\n\r\n\r\n<p>Let\u2019s break it down with an example for your\u00a0G&amp;A Rate:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Projected G&amp;A Costs: $300,000<\/li>\r\n\r\n\r\n\r\n<li>Projected TCI Base: $2,000,000<\/li>\r\n\r\n\r\n\r\n<li>G&amp;A Rate\u00a0= 300,000 \u00f7 2,000,000 =\u00a015%<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>This 15% would be your provisional G&amp;A rate, applied to your invoices until a final indirect cost rate is established after year-end.<\/p>\r\n\r\n\r\n\r\n<p><strong>Step 4: Prepare Your Supporting Documentation<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Under FAR 42.704, PBRs must be supported by reasonable, auditable projections. That means:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>You should have\u00a0justifications and assumptions\u00a0for each number.<\/li>\r\n\r\n\r\n\r\n<li>Prior year actuals can be used, but they must be adjusted for changes (e.g., growth, headcount, new contracts).<\/li>\r\n\r\n\r\n\r\n<li>Be prepared to explain why your selected base is appropriate.<\/li>\r\n\r\n\r\n\r\n<li>If DCAA requests a billing rate proposal, follow\u00a0<a target=\"_blank\" rel=\"noreferrer noopener\">DCAA\u2019s ICE model guidelines<\/a>\u00a0for documentation format.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p><strong>Why This Process Matters<\/strong><\/p>\r\n\r\n\r\n\r\n<p>Too often, GovCons submit incomplete or unsubstantiated rates leading to delays, disapprovals, or even payment holds. Misaligned PBRs create downstream problems like:<\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li>Underbilling\u00a0that hurts cash flow<\/li>\r\n\r\n\r\n\r\n<li>Overbilling\u00a0that triggers audit findings<\/li>\r\n\r\n\r\n\r\n<li>Invoice rejections\u00a0that slow down your revenue<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p>By calculating your rates methodically and aligning with FAR 42.704 guidance, you\u2019ll not only ensure compliance you\u2019ll gain billing predictability and strengthen your relationship with your Contracting Officer or DCAA point of contact.<\/p>\r\n\r\n\r\n\r\n<p><strong>What\u2019s Next in the Series?<\/strong><\/p>\r\n\r\n\r\n\r\n<p>We\u2019re just getting started.
