Snowball calculators

MPEARSON

Does anyone know of a snowball calculator that correctly takes into account introductory / balance transfer offers?
I've tried the one on stoozing.com but I'm sure it's ignoring the 0% period.
Also tried whatsthecost.com

One of my cards has a £3k balance transfer of 0% for another 17 months. This cards "normal" APR is the highest of my debts, at 29.9%.

Disposable income of £500 set in the calculators.

Correct me if I'm wrong, but using these figures I could delay paying this card for another 11 months, while paying off other interest bearing debts. Then on month 11 start paying £500 until that particular card is cleared. Or wait until month 17 and start then.

But both of the above calculators says to pay this card first. All £500 from month 1 until it's paid off. It then moves on to the next highest standard APR, again disregarding it's 0% offer.

I could come up with a spreadsheet but if anyone knows one out there please let me know.

I find it easier to put 0% into the stoozing one and do a new calculation as that nears its end

Yeah probably easiest way thanks. One of my card has 6 different balance transfer amounts and various end dates, so it starts getting complicated with these calculators.
I'll just work it month by month with the highest interest rates.

I think the models are wrong as you also need to have a savings account included.

If there is a min payment and zero % then only the min payment should be made.

at the point the interest kicks in is the time it needs paying in the mean time cash should be accumulated or go to lower rate.

The issue is that the interest saved on a lower rate(above zero) over a period may be less than the interest on a higher rate later on.

Not sure if that would be an easy model without trying, probably starting with something a bit simpler and building up

What would be easier is to model the cashflow/interest paid and eyeball the point you need to swap from paying off a debt to saving to cover a higher rate later.

Also complicated by the chances of other low cost borrowing.
