Financial Calculators

Interactive Financial Planning Tools

SenticMoney includes four free financial calculators with interactive charts, scenario comparisons, and actionable insights to help you plan your financial future.

Free Feature: All calculators are available to every user at no cost, no license required.

Calculate your full monthly mortgage payment including principal, interest, taxes, insurance, and PMI.

Inputs
  • Home Price — Purchase price of the home
  • Down Payment % — Percentage of home price paid upfront (default 20%)
  • Interest Rate — Annual interest rate (e.g., 6.5%)
  • Loan Term — Length of loan in years
  • Property Tax Rate — Annual property tax as % of home value
  • Home Insurance — Annual insurance premium in dollars
  • Extra Payment — Additional monthly payment toward principal (optional)
What You Get
  • Monthly payment breakdown with donut chart (P&I, tax, insurance, PMI)
  • Total cost of the loan and total interest paid
  • Extra payment savings — interest saved and time shaved off
PMI (Private Mortgage Insurance) is automatically included when down payment is less than 20%.

See how long it will take to pay off a credit card balance and how much interest you'll pay.

Inputs
  • Balance — Current credit card balance
  • APR — Annual percentage rate (e.g., 22%)
  • Monthly Payment — How much you pay each month
What You Get
  • Total cost hero number with principal vs interest donut chart
  • Payment scenarios table — see how paying 1.5x, 2x, or the 12-month payoff amount saves you money
  • Progress bar showing what portion of payments goes to principal vs interest
Your monthly payment must exceed the monthly interest charge, otherwise the balance will never decrease.

Project how your savings will grow over time with compound interest and regular contributions.

Inputs
  • Initial Amount — Starting savings or investment balance
  • Annual Return Rate — Expected annual return (e.g., 7% for index funds)
  • Years — How long you plan to save
  • Monthly Contribution — Amount added each month (optional)
What You Get
  • Future value hero with growth percentage badge
  • Donut chart — contributions vs interest earned
  • Growth area chart — visual curve showing balance growth over contributions-only line
  • "What if you contributed more?" scenario table with 4 options
  • Milestone badges — when your balance crosses $10K, $25K, $50K, $100K, etc.
  • Year-by-year breakdown table with interest earned per year

Compare two popular debt payoff strategies to find which saves you more money.

Inputs
  • Debts — Add each debt with name, balance, APR, and minimum payment
  • Extra Payment — Additional monthly amount beyond minimums to accelerate payoff
The Two Strategies
  • Snowball — Pay off smallest balance first. Quick wins build motivation.
  • Avalanche — Pay off highest APR first. Minimizes total interest paid.
What You Get
  • Balance over time chart — two declining lines showing both strategies
  • Payoff timeline — horizontal bars showing when each debt gets eliminated
  • Strategy cards with first-win badges, total paid, and formatted time
  • Winner card showing which strategy saves more and by how much
When your smallest debt also has the highest APR, both strategies will be identical (a tie).
Tips for Using Calculators
  • Run the same calculator multiple times with different inputs to explore "what if" scenarios
  • Use the compound savings calculator to see the dramatic effect of starting early — even small contributions grow significantly over 20-30 years
  • For debt comparison, adding even a small extra payment (e.g., $50/month) can dramatically reduce total interest
  • All charts are interactive — hover over data points for exact values
