Free calculators

Free calculators for budgeting, debt payoff, savings goals, sinking funds, net worth and homeschool hours. No sign-up, nothing stored, works on any phone. Bloggers and teachers can embed any of them for free.

Net Worth Calculator

Your net worth is everything you own minus everything you owe. Type your numbers below and the total updates as you go. Nothing you enter leaves your browser.

50/30/20 Budget Calculator

The 50/30/20 rule splits your take-home pay into 50% for needs, 30% for wants and 20% for savings and extra debt payments. Enter your pay to see your numbers.

Debt Snowball Calculator

List your debts and how much extra you can pay each month. The calculator shows when you will be debt-free with the snowball method (smallest balance first) and the avalanche method (highest interest first).

Savings Goal Calculator

Pick a goal, such as an emergency fund, a down payment or a trip, and a deadline. The calculator shows how much to set aside each month, each paycheck and each week to get there on time.

Sinking Funds Calculator

A sinking fund is money you set aside a little at a time for a cost you know is coming. Add your upcoming expenses below to see the monthly amount for each fund and in total.

Homeschool Hours Calculator

If your state asks you to log instruction hours, this calculator shows whether your current schedule gets you there by the end of the school year, and how many hours a day you need if it does not.
