Smart Calculator

Finally know what's
safe to spend

Simple Financials shows your real available balance — accounting for paychecks, holidays, recurring expenses, loans, and life’s surprises.

How does Simple Financials track income and expenses?

Simple Financials is built for how your money actually works — handling paycheck variations, annualized bills, auto-expiring loans, and multiple income sources, all in one place.

📅

Annualized Expense Splitting

Set a yearly due date, recurrence frequency, and installment frequency. The app divides the total and shows you exactly what to set aside each month — no surprises when that big bill arrives.

🏦

Loans That Auto-Expire

Enter your installment amount and remaining payment count. The loan disappears from your expense sheet the moment it’s paid off — your safe-to-spend number automatically improves.

🏦

Current Balance Baseline

Start by entering your current account balance. Everything flows from there — income adds, expenses subtract, and you always know your real number.

💵

Multiple Income Sources

Add as many income streams as you have — salary, freelance, side income. Each gets its own schedule and amount, all factored into your available balance automatically.

Can I forecast my bank balance for the week, month, or year?

Simple Financials projects your safe-to-spend balance across four time horizons — accounting for holiday pay reductions, loan payoffs, and installment schedules.
