Frequently asked questions
What is DecidePlan?
It's a decision-support tool that turns "how much should I spend on X?" into a specific, personalized spending range. It covers 20 major purchase categories, from weddings and home renovation to cars and laptops.
Is DecidePlan free?
Yes. The calculator that gives you a Comfortable, Sweet Spot, and Stretch range is free to use, with no account required. A paid Digital Decision Kit ($19 as of 2026) is available per category for a full line-item planning system — see the category page for current pricing.
How is my spending range calculated?
Each category uses a deterministic model, not an AI guess: it takes your income, savings, debt, and category-specific factors, then computes a range using sourced benchmark data and an affordability model. The same inputs always produce the same output.
Does DecidePlan sell financial advice?
No. It's a decision-support tool, not a financial advisor and not a price-comparison or coupon site. It is not a licensed advisory service.
Are the recommended ranges influenced by affiliate commissions?
No. Some outbound links are affiliate links and may earn DecidePlan a commission, but this never changes the calculated Comfortable, Sweet Spot, Stretch, or Above-This numbers a user sees.
