The Ad Budget Optimizer is a free online tool that splits a total advertising budget across multiple channels — such as Google Ads, Facebook, Instagram, LinkedIn, and TikTok — to maximize the conversions or revenue you can expect from your spend. Instead of dividing money evenly or by gut feel, you describe each channel with its pricing model (CPC per click or CPM per 1,000 impressions), its conversion rate, and its average order value. The optimizer then weights every dollar toward the channels with the highest expected return and shows you a recommended split. You can add or remove channels, pick a currency, choose whether to optimize for conversions or ROAS, reserve a slice for testing, and compare the optimized plan against a plain equal split. For each channel you get the projected budget, clicks or impressions, conversions, revenue, and ROAS, plus blended totals and a budget-split chart. Everything runs in your browser with no signup.
Building an optimized multi-channel plan takes only a minute:
Splitting a budget evenly wastes money on weak channels and starves the ones that actually convert. By weighting spend toward each channel’s expected return — derived from its cost model, conversion rate, and order value — the optimizer points your money where it works hardest while keeping the math transparent. The optimized-versus-manual comparison shows exactly how many extra conversions the smarter split is worth, so the recommendation is easy to defend to a client or a manager. A testing reserve lets you keep funding experiments without risking the whole budget, and the currency selector and ROAS view make the plan usable for any market or revenue goal. Because every change recalculates instantly, you can model several scenarios in seconds. All calculations happen locally in your browser, so your budget and performance figures stay private.
With a $10,000 budget, set each channel’s CPC, conversion rate, and average order value, then optimize for revenue. The tool funnels more budget to high-ROAS channels and projects total revenue and blended ROAS.
Model display or video channels on a CPM basis and search or social on CPC. The optimizer normalizes both to expected conversions per dollar so they compete on the same footing.
Set a 15% testing reserve so that slice is spread evenly across channels for experimentation, while the remaining 85% is optimized by expected return.
It estimates each channel’s expected return per dollar from its pricing model, conversion rate, and average order value, then allocates budget in proportion to those returns for the goal you pick — conversions or revenue.
CPC is the cost per click and CPM is the cost per 1,000 impressions. The tool converts both into expected conversions and revenue per dollar so channels priced differently can be compared fairly.
Manual is a plain equal split of the budget across channels. Optimized weights the spend by expected return. The summary shows how many more conversions the optimized plan is projected to deliver.
Yes. Add or remove any number of channels, name them whatever you like, and choose your currency. The projections and chart update for whatever mix you enter.
No. All calculations happen inside your browser, so your budget, costs, and performance figures are never uploaded or saved on a server. Your data stays private.
