    Ad Budget Planner Calculator for Channel Spend and Target ROAS

    How to Calculate Allocate Spend by Channel with the Ad Budget Planner Calculator

    Plan an advertising budget from revenue goals, target ROAS, channel performance, and expected returns. Compare scenarios before allocating paid media spend.

    Formula

    Budget = target conversions x CPA; funnel revenue = spend / CPC x rates x value

    How to use the result

    Compare channels on expected contribution profit and uncertainty, not reach or ROAS alone.

    Forecasts assume entered rates remain stable as spend changes; real channels often have diminishing returns. Inputs and calculations stay in this browser.

    Plan your advertising budget, allocate spend across channels, and maximize your marketing ROI.

    Budget from Revenue Goal

    Calculate the ad budget needed to achieve your revenue target.

    Budget Formula

    Ad Budget = Revenue Goal ÷ Target ROAS

    Example: To generate $1M revenue with 4x ROAS, you need $250K in ad spend.

    Channel Budget Allocation

    Allocate your budget across advertising channels and forecast revenue.

    Channel ROI Comparison

    Compare the revenue potential of two advertising channels.

    Budget Optimizer

    Calculate how much budget you need to increase to hit a revenue target.

    Note: This assumes linear scaling at your current ROAS. In practice, ROAS often decreases as you increase spend due to audience saturation.

    Ad Budget Planning Best Practices

    Start with Goals, Not Budgets

    Define your revenue targets first, then work backward to determine the required ad spend. This ensures your budget is tied to business objectives.

    Diversify Your Channels

    Don't put all your budget in one channel. Diversification protects against algorithm changes and platform-specific issues.

    Account for Diminishing Returns

    ROAS typically decreases as spend increases. When scaling budgets, expect efficiency to drop and plan accordingly.

    Reserve Budget for Testing

    Allocate 10-20% of your budget for testing new channels, creatives, and audiences. This helps you discover new growth opportunities.

    What is an ad budget planner?

    An ad budget planner helps you translate business targets (like revenue goals) into a realistic advertising budget. Instead of guessing spend, you model the required budget from your expected ROAS, then stress-test different mixes and scaling scenarios.

    How to use the Ad Budget Planner

    Budget from Goal

    1. Enter your Annual Revenue Goal.
    2. Set a Target ROAS based on recent performance (use a conservative number for planning).
    3. Use the output to estimate the total ad budget needed to hit the goal.

    Channel Allocation

    1. Allocate your budget across channels with Allocation (%).
    2. Adjust Expected ROAS per channel to reflect differences in efficiency.
    3. Use the results to build a diversified mix rather than relying on one channel.

    ROI Comparison

    1. Compare multiple spend/ROAS scenarios (channels, creatives, or audiences).
    2. Prioritize the scenario with better expected return and acceptable risk.

    Budget Optimizer

    1. Enter current spend and current ROAS as your baseline.
    2. Set a target revenue and review the required spend and implied increase.
    3. Plan for diminishing returns as you scale, especially on saturated audiences.
