What a finance charge is
A finance charge is the cost of borrowing. It is the interest added to a balance. So it is what credit costs you each period. Cards and loans add it on a cycle. The rate is usually set per month. This tool puts a number on it.
How it is calculated
The tool takes your balance. It multiplies it by the periodic rate. So a bigger balance means a bigger charge. A higher rate raises it too. The result is your finance charge. The calculator runs the numbers for you.
What the result tells you
The result shows your finance charge. A two thousand balance at one point five percent costs thirty. A bigger balance raises it. A higher rate raises it too. So it shows the cost for the period. It reads clearly at a glance.
The balance
Your balance is the amount you owe. It is the sum the rate applies to. A bigger balance lifts the charge. So this number sets the base. Use the balance for the cycle. It drives the entire result here. Enter your balance.
The periodic rate
Your periodic rate is the rate per cycle. It is often a monthly figure. A higher rate lifts the charge. So this number drives the cost. Use the rate on your statement. It is smaller than the yearly rate. Enter your periodic rate.
Why finance charges matter
A finance charge is the real cost of carrying debt. It adds up every single cycle. So a balance left unpaid keeps costing. The charge can snowball over time. It is why paying in full helps. Watch it on every statement.
How to lower it
You lower the charge by cutting the balance. Pay more than the minimum each cycle. So less balance means a smaller charge. A lower rate also helps a lot. Move debt to a cheaper card if you can. Every dollar paid cuts the next charge.
Periodic rate versus APR
The periodic rate and APR are linked. The APR is the yearly headline rate. So the periodic rate is the APR split by cycles. A monthly rate is the APR over twelve. Both describe the same cost. Check which one your card shows.
How to use it
Enter your balance first. Add the periodic rate. Read the finance charge in your chosen currency. Then try a lower balance. Compare two rates. Plan your next payment. Use it to cut your costs.
A final tip
Use this to see the cost of a carried balance. Remember the charge repeats every cycle. Paying in full avoids it entirely. A small balance still adds a charge. Aim to clear the balance fast. Do not let it build over months. Less debt means a smaller charge.
