How to use Balance Transfer Savings Calculator
- Confirm the amount eligible for transfer, fee, promotional APR, end date, and post-promotion APR from the issuer's terms.
- Enter a payment that fits the budget and check whether it clears the balance before promotion expiry.
- Avoid adding new purchases unless their APR, grace period, and payment allocation are modeled separately.
Calculator guide
Understanding Balance Transfer Savings Calculator
A balance-transfer offer saves money only when the transfer fee, promotional interest, planned payments, remaining post-promotion balance, and later APR together cost less than the current-card payoff path.
Calculation method
How the calculation works
Add the transfer fee to the new balance, model the promotional window explicitly, and compare remaining post-promotion interest with the current-card payoff plan. Calculate the current fixed-payment payoff, add the percentage transfer fee to the new balance, amortize during the promotional window, and continue any residual balance at the post-promotion rate.
Transfer plan
Use the promotion as a fixed payoff deadline
The strongest transfer plan works backward from the expiry date.
Worked situations
Practical examples
- A 3% fee on a $10,000 transfer adds $300 before any interest.
- A 0% promotion can still be expensive when payments leave a large balance for the post-promotion APR.
- Estimated savings can be negative when the fee and later interest exceed current-card interest.
Better inputs
Useful tips
- Schedule automatic payments above the required minimum.
- Use the issuer's exact promotion end date rather than an assumed number of statement cycles.
- Keep the old account's residual interest and trailing charges in the payoff checklist.
Before relying on the result
Limitations and common mistakes
- Issuers may accrue daily interest, allocate payments differently, revoke promotions after late payment, or apply separate purchase and cash-advance APRs.
- Minimum-payment formulas and changing payments are not modeled.
- Credit approval, transfer limits, taxes, and credit-score effects are outside the calculation.
